MOMENTUM 4 Wireless Noise Cancelling Headphones Bluetooth Headset for Crystal-Clear Calls with Adaptive Noise Cancellation, Up To 60HR Playtime, Folding Design, Black/Copper

TL:DR While they may have some idiosyncracies, they are totally worth learning to manage as the sound, battery, and general functionality is excellent I've been using these for the past 5 months and can honestly say they are one of the best pairs of headphones I've used in a VERY long time. While they might not be "perfect" in all areas, they are excellent in enough to assuage the issues. The sound quality via bluetooth is absolutely EXCELLENT, they have a -very- wide soundstage compared to a fair number of bluetooth headphones I have tried, and also have a very clean, separated sound, all the elements are clear and distinct to the point I've heard things in songs and videos that I had not before even listening through my monitor set up. I've not tried them wired, where they could be even better because the BT is so good (YMMV I spend time shaping the EQ in the app which is well worth the time) Battery life is top tier, I wear them while commuting and on breaks, and often wear them of an evening connected to my PC and seem to only have to charge them every few weeks. They also have a neat function were they pause the music when you take them off and seem to go into sleep mode until you put them back on They can be connected to multiple devices, although this is where some minor issues start to appear. I have mine connected to my phone and my pc via a bluetooth dongle - unless you don't manually put the headphones to sleep using the power button, you can sometimes have devices register a connection to the headphones, which can pause things you're listening to through speakers. They come with a sturdy headphone case that has spaces for, and includes, relevant cables e.g. USB and headphone, and the headphones fit very nicely in to it, which is useful as they do not fold in any way. They are portable with some planning.. or a thin neck I guess! The touch controls are a great idea and work really well in principle... but as alluded to I have a thick neck, and it is tremendously easy to "press play" on the earcap with my chin 😅Also the double tap for ANC doesn't register as well as it should, but the increasing/decreasing ANC motion does. There is an app that seems expected to get, but is also totally worth the download. Has its own equaliser to be configured, as well as other ANC controls, being able to configure sound zones using the ANC microphones and others beside. I got them with a fairly good discount in a sale, but would not have been disappointed if I had paid full price

The very first thing you need to do is update the app that is downloaded to control the headphones, improves the sound quality and offers more flexibility of settings. The second thing is to fit the cooler ear padding that are on offer not only are they a much better fit but actually improve performance and sound quality. Straight out the box I found these to be overwhelming in the bass and quick to heat up making them uncomfortable but after the update app and fitting the cooler pads they are extremely comfortable and sound amazing with a flat response that can easily adjust to your preferred liking. Changing the ear pads is a bit of a struggle but well worth the improvements they bring, highly recommended once updated my only complaint is the clunky volume control which needs improvement Sennheiser take note and update your app again.

The Sennheiser MOMENTUM 4 Wireless headphones bring significant upgrades to Sennheiser's premium line, competing directly with top-tier noise-canceling headphones from brands like Sony and Bose. Controls: The MOMENTUM 4 employs intuitive touch controls on the ear cups for play/pause, volume adjustments, and track navigation. Sennheiser has also included wear-detection sensors, pausing playback when you remove the headphones and resuming when you put them back on. Connectivity and App Integration: Equipped with Bluetooth 5.2, the MOMENTUM 4 offers a reliable, high-quality connection. The Sennheiser Smart Control app provides customization options, including EQ settings and a sound personalization feature that adjusts based on your listening preferences. Battery Life: With a remarkable 60-hour battery life (at moderate volume with ANC on), these headphones outlast most competitors in the category. Quick-charging provides about six hours of playback with just a 10-minute charge. Noise Cancellation (ANC) and Transparency Mode: The Adaptive Noise Cancellation is quite effective, especially in noisy environments like planes or public transport. Transparency Mode allows external sounds in, which is useful for conversations without removing the headphones. Sound Quality: Sennheiser is known for its audio fidelity, and the MOMENTUM 4 stays true to this legacy. It delivers a clear, balanced, and rich sound profile, which can also be customized in the app. Here’s a breakdown of its performance across sound characteristics: Bass: Deep, punchy bass without being overbearing, making it suitable for genres like hip-hop, electronic, and pop. Mids and Highs: Vocals and instruments are detailed, and highs are crisp without becoming harsh. This makes it ideal for everything from classical and jazz to rock. Soundstage: The MOMENTUM 4 has an impressively wide soundstage for closed-back headphones, allowing for excellent separation and positioning of sounds. The headphones also support high-quality codecs, including aptX Adaptive and AAC, which enhance sound quality over Bluetooth. Pros: Outstanding battery life (up to 60 hours) with fast-charging capabilities. Exceptional sound quality that’s clear, detailed, and customizable. Effective Adaptive Noise Cancellation that competes well with top ANC models. Comfortable and lightweight design, suitable for extended use. Stable Bluetooth 5.2 connectivity with support for high-quality codecs. Cons: Less distinctive design compared to previous MOMENTUM models, which may disappoint fans of the original look. Touch controls can be somewhat sensitive, occasionally leading to accidental triggers. ANC isn’t industry-leading; while it’s very good, it’s slightly less effective than Sony’s and Bose’s top models in extremely noisy environments. Final Verdict: The Sennheiser MOMENTUM 4 Wireless headphones are an excellent choice for listeners who prioritize sound quality, comfort, and long battery life. They strike a great balance between premium audio performance and advanced features like ANC and transparency mode, making them versatile for daily use, travel, and dedicated listening sessions.

I'll start with the most egregious negative first; I'm on my second pair of Momentum 4's. The original pair I sent back to Sennheiser for RMA, because they started crackling in the left earcup. Now, this pair has started crackling, also in the left ear cup. I bought my original pair for £209 on October 9th 2024. I am writing this October 21st 2025. That makes two pairs of headphones, exhibiting the same fault in just over ONE YEAR. I won't bother RMA-ing this pair, since I expect I'll just get the same issue in another 6 months. To be clear, I've used them with factory settings, apart from enabling AptX HD. They haven't been exposed to water, and I listen at about 30-40% volume. If you're still considering buying these for some reason, the pros and cons are as follows. Pros: * The sound quality is decent, though not amazing given the price. * The companion app is surprisingly functional (and doesn't require sign-in, amazing!), with a 5 band EQ, access to ANC settings, and an option to prefer AptX HD when using Bluetooth. * The battery life is decently long, I can't give an exact number, but I found I only needed to charge every 5-7 days or so, with on and off usage, and the headphones are decently comfortable. Cons: * The headphones are 100% plastic, including the earcup hinges, which creak if you dare move while wearing them. * The active noise cancellation is present, but more noise reduction than cancellation. Fortunately, you can disable wind reduction in the app, which improves the noise cancellation, but, unsurprisingly, increases wind noise. On a positive note, the transparency mode is surprisingly transparent! * The Bluetooth playback in AptX HD mode is weirdly spotty, sometimes it's rock solid, staying connected through multiple walls, and sometimes it hitches at less than a meter away. I've found that the Qualcomm Wi-Fi/Bluetooth chipset in my laptop is more reliable than the Realtek one in my ThinkPad, and most surprisingly, better even than the BTD600 dongle. * The final issue; sometimes, the controls decide they don't want to work properly. Sometimes, both the volume up and down gestures *increase* the volume. Sometimes, taking the headphones off doesn't pause the currently playing media, but putting them back on does. Sometimes, tapping the right earcup (the play/pause gesture) when connected to two devices - a selling point of these headphones - doesn't pause the currently playing content, but starts whatever was last playing *on the other device*. Even ignoring the quality (control?) issues, I probably wouldn't recommend these headphones. The build is subpar, the ANC - again, a selling point - is *far* behind the competition, and the Bluetooth is far flakier than other headphones I've tried, and that's saying something.

It was between MOM4's and the Sony's WH-XM5's. It was either the quality of the sound vs the ANC's so I opted for the MOM4's due to the quality of the sound and I made the right choice. I brought these on Prime Day and had a £100 voucher so I got them dead cheap. The case is smaller then I expected and the fabric which covers it makes it look that extra premium. It's sturdy and easy to carry. The extra's are the C-Type USB cable, AUX cable and airplane adapter. The headphones look exceptionally premium with the same fabric covering the top part of the head frame and fake leather underneath giving it an extra cushion feel. The ear cups fit well against my ears and are very comfortable. I can keep them on for hours without any issues. There is a hard button to turn the device on/off but I have never used it. As soon as I pull them out of the case, they turn on; when I have finished using them they auto turn off which can be set via the app. Everything else is touch controlled and it's sensitive, maybe a little too much causing it to pause, skip tracks. The sound it is not the loudest so I expected more for the price but these are very big on bass and exactly what I needed. I'm not so keen on ANC and I can barely tell if it's in use or not because I always have the volume on max so I can't hear anything anyway. I've had these for a couple of month's now and I've charged them once or twice, the battery life is great. The app is certainly required to adjust the settings and it makes a difference to how they sound, which is better than straight from the box. Overall, made the right choice purchasing the MOM4's and for the price at less than £125, it was a no brainer.

I spent some time considering the Sennheiser Momentum 4 and the Sony WH-XM4. Both excel as over-the-ear, sound-cancelling headphones. I eventually opted for the Momentum 4, and I have to say the quality and richness of the sound surprised me. Sony is well known for heavy bass, but Sennheiser takes the same punchy bass but delivers it with precision. It's impressive. The build quality feels robust. The ear pads can also be replaced should the leatherette deteriorate. The headphones are easily adjusted. I feel I have quite a large head, and each cup can easily be extended. I do find the clamping force a bit stronger on the Momentum 4 compared to my Sony WH-XM3, but it is light enough for extended use. The case included with the headphones is equally sturdy and likely to offer good protection. I find it slim, but slightly bulky, yet still slides into my bag without much fuss. It does include the necessary cables if you do not plan to use wirelessly. Admittedly, the 2.5mm jack on the headset took me by surprise. I am more familiar with 3.5mm, but, longer cables are easy to find and inexpensive. The battery life is second to none. I rarely have to charge the headphones. The touch controls are also intuitive, especially if you have used similar inputs. I really enjoy the transparency mode, which is one-touch activated. On previous Sony's I've owned you had to hold your hand awkwardly over one cup to activate. There are a few niggles to overcome. I've had more than a few instances where I've turned the headset on and it's not automatically paired with my iPhone. I have to manually head to the Bluetooth settings and reconnect. A slight annoyance if nothing else, and thankfully it hasn't dropped the connection while I'm listening to music. The noise cancelling is still great, but, struggles in wind, which can be picked up by the microphones. The microphone quality during calls is acceptable (7/10). Still, for the price I paid, they should provide years of crystal clear, punchy music and I am happy to recommend.

What a bargain - £219 for the black and copper special edition! So glad I held off till Black Friday. I only have positives for these. First off, the case is quality - sturdy, smart and actually smaller than I was expecting. Then the fit, which is a deal breaker. I have a big head but these fit with room to spare. They’re very light too. Setting up is a breeze - they’ve introduced some new firmware which fixes the usual bugs, but they’re obviously put a bit of effort into these because there’s now a 5 band EQ in the app (previous reviews only reported 3 bands). Now the main reason for me choosing these over the Sony WH1000xm5 - the sound quality. They’re fantastic, right off the bat. If you’re after a balanced or neutral sound then you’re better off considering passive headphones and a Bluetooth receiver such as the FIIO BTR7, rather than a pair of Bluetooth headphones. The low end is there but it isn’t drowning out the mids and highs - it’s just a warm, rich sound with a satisfyingly wide sound stage. Plus, you can easily tone down the low end with the app equaliser, though I personally haven’t felt the need to change it. I can’t comment on the battery life although with a reported 60 hours it’s hopefully not a concern. Noise cancellation seems to do the trick - I couldn’t here a thing going on in the house with these on. They connect to various devices with ease. So all in all, these are great. If they’re still at the sale price I’d get in quick (the standard black edition is £240 at the time of writing but they still have the special edition in stock).

I was so excited to get the Sennheiser Momentum 4 and I didn't realise they did a special edition version which is the one I ended up buying. This is the first time I ever seen special edition arrive in a basic brown box it felt like I'd purchased refurbished headphones. I quicky went back on my order page to see if I did buy a refurbished one and I didn't. Appers the special edition comes in this brown box with no extras just a different colors trims, where as the standard edition comes in this nicer box with a nice welcome card. Once I got past the package I was presented with a nice solid case in the case was the headphones with gray band and with copper trims, it looks nice. Also in the case was a usb-c charging cable, a 3.5mm audio cable but upon closer inspection the cable is 3.5mm on one end and 2.5mm one the other and a plane adapter. I wish a microfibre cloth was included because these headphones are a fingerprint magnet due to the touch controls you are constantly having to make contact with the right ear cup however, the touch control was easy to get used to so no problems there for me, but on head detection does not always work. You put them on your head and the music plays very cool you take it off it does not pause the music as it's supposed too. Whilst trying to search on how to fix this I read so many issues with this headphones regards the on head detection failing and some reports of bluetooth disconnects. Although my bluetooth does not disconnect per-say but it does a weird thing, I'll try to explain the best way I can, my music is playing, if I put the music app in the background so I can for example send a message the music cuts out for 2 seconds then comes back. If I bring the music app to the foreground after it being but in the background, the same thing happens the music cuts out for 2 seconds the only way to stop this is let the music play and not to put the music app in background or multitask. Sound quality is good, I listen to electric music and just left the settings on flat for the headphones and use my music players own EQ to tweek to my taste. Noise canceling is good. Battery is good, I use the headphones for 2hrs per day and I loose 10% per day, bere in mind my music is in HQ and my phone and these headphones are set to play in HQ. They do have some weight to them so it will take some time getting used to having them on your head, they are comfortable though and value wise they are quite expensive side. I'm hoping there will be a firmware update soon to fix these bugs I'm experiencing.

Da tempo ormai al pc sfrutto le cuffie, soprattutto nelle ore notturne durante il gioco, per non disturbare ed avere una maggiore immersività. Avendo a disposizione un DAC audio di qualità utilizzavo dei modelli a filo, con l'unica pecca che non abbia un selettore dedicato per switchare fra casse e cuffie, il che rendeva un po' scomodo il passaggio. Da quando però ho riconfigurato la mia postazione, il cavo diventa scomodo perchè devo rimuoverlo tutte le volte dopo l'utilizzo o mette disordine sulla scrivania e devo raccoglierlo in un cassetto. Oltretutto dopo l'ultimo modello con i padiglioni rovinati dal tempo avevo preso un paio di Sennheiser HD599 delle quali ho letto bene ma ho riscontrato una qualità bassissima rispetto ad altre di pari costo e che ho prontamente messo in un cassetto e li ci sono rimaste. Ho optato dunque per un modello wireless con cancellazione del rumore e specifiche di livello elevato sulla comunicazione bluetooth. Purtroppo dopo un aggiornamento windows il bluetooth non ha più funzionato in modo efficace, principalmente nella sua funzione comodissima di commutazione del segnale una volta accese le cuffie, dovendo sempre trafficare nelle impostazioni per utilizzarle, cosa ancora più scomoda del filo di prima. Peggio ancora ha inibito la cancellazione dei rumori, la quale si disattiva sempre dopo 3 secondi dall'avvio e senza alcun verso di farla funzionare. Ho provato a risolvere con aggiornamenti e programmi audio, ma la situazione è solo peggiorata, rendendo le cuffie inutili. Ho così deciso di investire un po' di più per questo modello di alto livello con il suo dongle usb per la massima qualità e la situazione è cambiata notevolmente. Innanzitutto sono confortevoli indossate, padiglioni grandi ed archetto morbido. Non si possono ripiegare come altre concorrenti, ma vengono vendute con la loro custodia rigida nella quale si ripongono perfettamente. In dotazione arrivano un paio di cavi e connettori (possono essere usate via cavo) e manuali vari, il tutto nella custodia che funge anche da auto-spegnimento delle cuffie quando riposte, cosa comodissima perchè basta estrarle e si accendono immediatamente connettendosi in un istante. La qualità del suono è ottima, io sfrutto il dongle usb btd600 per i problemi prima elencati con il bluetooth del pc e ogni abbinamento è semplice così come la commutazione dell'audio. I brani in qualità flac e i video con codec ad alta qualità si sentono notevolmente meglio rispetto alle HD599, veramente un altro mondo. Peccato per quel modello in quanto sono una pecca rispetto altri modelli acquistati in precedenza sempre del marchio di cui sono stato pienamente soddisfatto. La cancellazione dei rumori è molto efficace, funziona bene, se pur non è totale e qualcosa di lieve passa comunque (credo che il top si possa solo avere con auricolari in-ear per l'isolamento che intrinsecamente forniscono), ma molto alta e comunque soddisfacente. Utilizzandole principalmente in casa è sufficiente ad isolare dai rumori di aspirapolvere o tv delle altre stanze. Il padiglione destro consente i vari comandi multi-touch semplici ed efficaci, senza dover cercare con le dita microtasti andando a tatto. La ricarica è tramite usbc, veloce e consente ore ed ore di ascolto, quasi da dimenticarsi che siano a batteria! Ovviamente l'ANC consumerà maggiormente energia, ma parliamo comunque di decine di ore senza problemi. Personalmente non le indosso per tante ore consecutive, a parte occasioni sporadiche, ma le trovo molto comode e per nulla pesanti, non fanno sudare le orecchie e in generale le trovo molto confortevoli. Dopo le varie disavventure con il bluetooth del pc, sono quasi contento di averle avute perchè mi hanno convinto a prendere questo modello che pienamente mi soddisfa e sto godendo di una qualità audio eccellente. Connesse al mio mac o all'iPhone funzionano perfettamente (ma anche le precedenti, il problema era solo legato a windows), sullo smartphone poi hanno l'app dedicata per impostare e regolare al meglio come più ci piacciono i suoni. Molto comoda poi la possibilità di un doppio abbinamento bluetooth così da non dover sempre fare la connessione ogni volta che si cambia dispositivo. In definitiva sono pienamente soddisfatto del prodotto, non le ho confrontate con le concorrenti Sony XM5 o addirittura XM6, ma al momento dell'acquisto costavano di più e dalle recensioni si equiparavano con piccole differenze a favore di uno o dell'altro modello, per cui sono rimasto fedele al marchio nonostante lo scivolone di quelle cablate. Ovviamente per il top della qualità audiofila ci sono modelli molto più specifici e costosi, tutti via cavo, ma alla versatilità e comodità di queste non rinuncerei mai, soprattutto utilizzate con tv e console, pc, smartphone, passando da uno all'altro in un attimo.

Solo llevo unas horas con ellos y no necesito más para reconocer un producto de calidad, brillantes, buenos acabados y bien pensados hasta el más mínimo detalle. No soy un experto audiófilo, no he tenido auriculares de 'prestigio' como los Sony, los Beats o los Airpod Max como otros que los comparan, solo tengo unos Airpods Pro de 1a generación y ya me parecían buenos, hasta que me he puesto estos, es otro nivel. La experiencia de uso la primera vez es una maravilla, bajar la app Smart Control Plus y te sumerges en el mundo de Sennheiser y ya no quieres salir de ahí, emparejamiento inmediato, personalización de la app, control total del dispositivo, información de batería, firmware, cancelación de ruido (ANC) y una guía para ajustar el sonido a tu gusto que, en menos de 3 minutos, te deja los auriculares como si los hubieras diseñado tú para tu música, espectacular. Se activan solos al ponértelos aunque los hayas apagado con el botón de Off) , se apagan si te los quitas, se pueden localizar a través de la app para saber dónde están, tiene diferentes ecualizadores predeterminados y el tuyo personal y para colmo puedes programar ajustes que se activan por posicionamiento, por ejemplo, en casa una configuración y en el trabajo otra y eso lo hace automáticamente cuando detecta la posición, brutal. Pero hablemos del sonido, que son para eso. Puedo decir que he redescubierto canciones que había escuchado cientos de veces, voces nuevas, instrumentos de fondo que no sabía ni que existían, detalles y hasta la respiración antes de una nota, todo en su sitio y equilibrado, la sensación de calidad te entra por los oídos y te estalla en el cerebro. Muchos se quejan de la cancelación de ruido, que no es la mejor, solo puedo compararla con mis Airpods Pro de 1ª generación y estos cancelan mucho mejor, probado hasta con la aspiradora, ni la oigo, sé que está encendida pero no la oigo, me parece magia y eso que ya tenía cancelación en los Airpods, no me viene de nuevo, pero me ha sorprendido. Los acabados Special Edition me parecen bellísimos, elegantes y sin estridencias, Llevo gafas y después de varias horas de uso en casa no he notado ninguna molestia, no se notan en la cabeza y no aprietan y aún y así no se caen para hacer un poco de deporte en casa con ellos puestos. Los controles táctiles me daban mucho miedo pero que va, lo dicho, esta gente lo tiene todo muy bien probado, funcionan perfectamente y te haces en 5 minutos con ellos, volumen, pausa, play, pasar canciones hacia delante o atrás, contestar llamadas, colgar o rechazarlas y hasta puedes variar la cancelación con pellizcos o anularla con doble toque, todo funciona perfecto, lo máximo que te puede pasar es que te recoloques el auricular y hagas una pulsación de pausa sin querer, hasta que aprendes como agarrarlo para eso y no tocar el panel táctil. La batería es de 60h, sí, no me he equivocado, 60h y con cargas de 5 minutos tienes horas de reproducción, me parece hasta mágico, que fabriquen móviles por favor. Para los que quieran que les sangren las orejas ya os digo que el volumen es más que suficiente pero tiene un límite, supongo que como protección auditiva, pero con cancelación no hace falta subir mucho porque solo oyes la música, el mundo desaparece. Los he comprado en Black Friday por 184€ después de verlos a 299 durante mucho tiempo, no puedo estar más contento con la compra, un acierto total, no hace falta que sea profesor de música para querer unos auriculares así, si te gusta tu música y quieres oír tus canciones con el mejor sonido posible estos auriculares no te van a defraudar. Ah, los he emparejado con mi tele LG y perfecto, calidad y buena sincronización de audio, ideales también para ver la tele por la noche o en la habitación y no molestar a la pareja o a los vecinos. Un 10 de auriculares, no sé cómo serán los otros de la competencia, pero tampoco quiero saberlo ya, cuando pruebas esta calidad entiendes por qué Sennheiser tiene la fama que tiene, se la han ganado a pulso con productos así.

PLEASE READ MY FULL EXPERIENCE Using it for more than 2 years daily , Previously using ath-M50X Pros : 1) Excellent Battery life- (not charged it more than 20 times in 2 year, always NC On -> meaning very good battery life over years) 2) Audio Quality over Bluetooth- Iphone stuck to AAC but still quiet decent and crisp, very clear bass(really low deep bass) , decent instrument separation , highs are also decent . Try Lorde's Pure Heroin album 3) Audio Quality Wired : Now it's a game changer as it is THE ONLY HEADPHONE WHICH CAN PLAY LOSSLESS OVER USB C and using mac I even don't need any amp 4) App : significantly improved and now it's flawless. 5) Equaliser : If you want to tweak its signature you can do it easily(5 Bands) 6) Noise Cancellation : easily handles Flight, City noise, Weird Neighbours 7) Bluetooth: Excellent range, 3 BHK house no problem at all + 2 Devices connected at same time 8) Call : No complaint over call by 2nd person ever 9) Comfort : 6-7 hours daily (Music + Podcast ) , very comfortable 10) PS5/TV/other Device: No lag in gaming(Connect it to Controller) or TV or Laptop 11) Rivalry: Best in segment-> Audio quality LOSSLESS + Biggest battery + decent NC (Deadly Combo) Cons: Just Nitpicking 1) Noise Cancellation: If your GF scream at you, it cannot handle it , THE TRUTH , Wished lil bit more NC HEADPHONE BUYING and USING GUIDELINE : 1) Only buy if you really love listening to music + Invest in best Music app (LOSSLESS) Apple Music 2) Headphone can't be used for exercise,Long travel -> sweat + Fast head movement + unhygienic, Use Earbud 3) Tweak EQ according to your taste 4) For long hour listening, be in AC room and also take break to rest your ears 5) For best experience-> keep calm ,low lights ,Comfortable Sitting ,Eyes closed,Only listening and no work nothing Nutshell: After using only professional headphones and studio monitors, I was lacking colour of Consumer products and it gave me what I was missing. I have tried SONY, BOSE but picked this just for audio quality, battery life and Comfort. JUST GO FOR IT

Muszę przyznać że nie spodziewałam się takiego szoku jakiego doznałem! Słucham moje ulubione stare kawałki i odkrywam je na nowo!,

Been down a rabbit hole and researching for about a month before deciding on the Sennheiser Momentum. Went to some local stores to try out all of the popular headphones but went in with a certain list of priorities (in order); 1) Sound Quality 2) Comfort 3) Portability 4) Noise Cancelling 5) Battery life Contenders on the list were: - Bose QC ultra: Amazing ANC, great portability, decent sound quality but a bit on the dull side. - Sony XM4 & XM5: Bassy but flat and muffled sound, great ANC and portability. Avoid the XM5 at all costs though, the hinges are a major design flaw. - Sennheiser Momentum 4: Blows everything else out of the water in terms of sound quality, same for the battery life. Not quite as portable as the QC ultra's and XM4s but comes with a great case nontheless. - B&W PX7: Didn't get a chance to try these out. Pro's; If you prioritise sound quality over anything else then it's an easy choice, nothing comes close to it in this price range. Track separation, bass, clear vocals... it's all there and it's an immersive listening experience. The ANC might not be as good as Bose or Sony but it's certainly nowhere near bad ANC performance. I recently brought these on multiple flights and trains with me and have 0 complaints. After having used Airpods Pro's for about 2 years I can confidently say that the transparency mode on the Momentums is pretty comparable too, which is a great thing. The controls (despite being touch) work surprisingly well but keep in mind that fingerprints are pretty visible on the black versions. As for the case it comes with, it looks a lot larger on the product page than it actually is in person. It's also very sturdy and packs some smart features which have worked flawlessly so far. When it comes to battery life... well it's probably the best on the market right now and almost feels like a challenge to drain it. If you don’t need the absolute best ANC on the market and want something that just objectively sounds better than any other consumer headphone in the €300 range, then the Momentums are a clear winner.
