WI-C100 Wireless In-ear Headphones - Up to 25 hours of battery life - Water resistant -Built-in mic for phone calls - Voice Assistant compatible - Reliable Bluetooth® connection - Black

Finding myself now using my phone for playing music more than in the past, and then finding the USB-C headphone adapter more of an annoyance than it was when I only used it occasionally, I decided it was finally time to get some bluetooth headphones... My first choice would have been Sennheiser, having been a fan of their wired sets for the past couple of decades, but the ones I had my eye on weren't available, so I started to look elsewhere for something that might be a suitable alternative in the meantime. My criteria were fairly straighforward - I wanted plain earbuds, decent battery life, easy recharging (i.e. direct USB connection, not via a charging case), and for the two buds to be connected so I could take them out and leave them hanging round my neck just as with wired buds. After a bit of searching, I'd narrowed down my list to either these or the similar C310, and as I've already got a few USB-C cables, the latter coming with a cable of its own wasn't enough to swing me towards that model given the 9 hour shorter rated runtime compared with the C100. Having now been using them for just under a week, I'm pleased to say these buds live up to their billing - as comfortable to wear for extended periods as my favoured Sennheiser buds, even with the extra weight of the control unit and battery resting against the sides of my neck. Sound quality is impressive given they're relying on their internal amplifier rather than being driven directly from the phone or laptop, and at full volume they pack a surprising punch. Perhaps not quite as bass-heavy as the Sennheisers, but still full bodied enough to put a smile on my face when the drums or bass guitars kick in. I haven't yet given the battery a full stress test, however after around 8 hours of use from full charge the reported charge level had dropped by 30%, which bodes well for them achieving the stated runtime. And recharging from the USB-C connection is easy and quick, so between the long runtime and fast recharge times its unlikely I'll find myself wanting to use them but being thwarted by a low battery warning. One thing I wasn't expecting from them was to be able to use them as a headset in Teams calls - I knew they had a microphone and could be used as a headset with a phone, but from what I've heard about other headsets it's not a given that they'll also work on a PC in that way, so this was a pleasant surprise. And whilst the audio quality here isn't quite as good as a dedicated headset with boom mic, it's easily good enough unless there's a lot of background noise - being able to switch instantly from listening to music to being in a call, without having to swap from headphones to headset and vice versa (as noted above, the C100's aren't quite as good as my headset for voice calls, but they're SO much better for music). Plus being wireless means I'm no longer tethered to the PC via the USB cable... On that note, with the PC in my upstairs office, I can walk around almost all of the house without dropping the connection - it's only once I walk into the extension out the back of the house that the signal cuts out, so the claimed 10m range doesn't seem unreasonable. Pairing the buds is about as easy as it gets with bluetooth gear these days - press and hold the power button until you hear them say they're in pairing mode, then select them from the list of available devices on whichever thing you're pairing them with. So far I've paired them with my phone and two laptops, and switching from one to the other takes just a few seconds, accompanied by another verbal indication of connection success. They're definitely a no frills set of buds - aside from the buds themselves, the only other thing in the small box aside from the instructions is a set of alternative earpieces in differing sizes, as is the norm with bud-style units. No USB cable or storage pouch or anything else like that, but what that means is that you're paying for the buds and nothing more, and that shows in the performance you get from them for your money. And I have to admit to being genuinely impressed with them, to the point where I'm starting to wonder if I'll bother replacing them with the Sennheisers I originally was after.

These get 5 starts from me as I bought them for using under a motorcycle helmet. The buds are very small and don't get pulled out your ears when putting on or taking off the helmet. They do exactly what I hoped - keep out a lot of the wind noise when riding and the sound level and quality is easily good enough to hear music while travelling. The battery life seems to be brilliant and the neck band and pods tuck under the jacket collar easily and nothing gets caught up or moved by the wind. I find them extremely comfortable and have had no trouble at all with the connectivity. As far as I'm concerned, they are brilliant.

The battery life makes this really good for sleeping in, or wearing for extended periods, without needing to recharge at all during the use period (no docking to get the extra promised hours of individual buds, you *will* get a full night's sleep with this). It's as comfortable to wear as regular wired buds, though the weight of the battery and transmitter pieces on the wire will make it want to tug out of your ears when you toss and turn, or walk around. Sound quality isn't super amazing out of the box, compared to the equivalent budget wired Sony earbuds (like MDR-EX15AP, which I recommend as a budget wired option, and you can use a cheap extender cable if needed), but it's more than sufficient for casual use, and especially sleeping whilst wearing. You can adjust the output with EQ software. The microphone is pretty clear, just be aware of fabric rubbing like any wired earphones, and just try it and see how you like it. I don't use this thing for calls, personally. I find this cheaper Bluetooth version WI-C100 better than the more expensive WI-C200 version. Barely any difference in functionality, this maybe even being the superior product, but this is cheaper. I easily get 16h+ out of these, plenty for a night's sleep, and time before and after that. Essential for me with sensitivity to neighbour noises, and needing sound to sleep. Whilst I only bought this because my new phone didn't have an AUX input, and the adaptors didn't work for my newer phone, it really is much more convenient. If you expect to wear this for 16h+ per night/day, you might want a second one to keep in a drawer/your bag, in case you wear out the battery before being able to recharge, which only takes maybe a couple of hours, and doesn't need an expensive wall charger. It comes with a USB-C port for charging. The 25h claim is overly optimistic (I assume this is done with the bare minimum volume and functionality). I would say maybe 18h would be the most to expect. Really, I can recommend these as a budget sleep-aid for us bad sleepers, especially those with misophonia and/or Asperger's (you can combine this with brown noise on your phone/computer to provide external noise masking, as there is no ANC (active noise cancellation) with these). Also, as just a cheap pair of Bluetooth earphones that can cope with sweat, it's still good option for all-day use, with adequate sound quality after you adjust the EQ to your liking. Note: These will automatically turn off when the USB-C is connected to power or a device, so cannot be used whilst charging, or as wired earphones. Damned companies removing useful 3.5mm ports.

The Sony WI-C100 wireless in-ear headphones have truly impressed me with their blend of affordability and reliable performance. If you're looking for a solid pair of everyday earbuds that won't break the bank, these are definitely worth considering. One of the standout features is undoubtedly the incredible battery life. Sony claims up to 25 hours, and in my testing, they've consistently come very close to that. This is a huge plus for anyone who's tired of constantly charging their headphones. I've used them for several days of commuting, workouts, and calls without needing to plug them in. This longevity makes them perfect for travel or long workdays. The water resistance is another welcome addition. While I haven't submerged them, they've held up perfectly fine during sweaty gym sessions and a few unexpected light rain showers. This gives peace of mind knowing they can handle the rigors of daily life. The built-in microphone performs admirably for phone calls. Callers have reported clear audio on my end, and I've had no trouble hearing them. The convenience of being able to take calls without reaching for my phone is a significant advantage. Voice Assistant compatibility is a nice touch. I've easily been able to activate Google Assistant with a long press of a button, allowing for hands-free control of music, calls, and information. This integration feels seamless and intuitive. The reliable Bluetooth® connection has been a consistent positive. Pairing was straightforward, and I've experienced minimal dropouts or interruptions, even in crowded areas. This stable connection ensures a smooth and enjoyable listening experience. In terms of comfort, the WI-C100 are lightweight and come with different sized ear tips, allowing for a secure and comfortable fit for various ear shapes. I've worn them for extended periods without any significant discomfort. The sound quality is perfectly acceptable for the price point. While they might not satisfy audiophiles looking for the most nuanced and detailed sound, they provide a balanced audio profile that's enjoyable for everyday listening to music, podcasts, and audiobooks. The bass is present without being overwhelming, and the mids and highs are clear enough for a pleasant listening experience. Design-wise, the black finish is sleek and understated. The neckband design is practical, allowing the earbuds to rest comfortably around your neck when not in use, preventing them from getting lost. The controls are easily accessible on the neckband, allowing for convenient volume adjustment, playback control, and call management. Overall, the Sony WI-C100 wireless in-ear headphones offer an excellent combination of long battery life, water resistance, reliable connectivity, and convenient features at a very competitive price. While they might not have all the bells and whistles of more premium options, they deliver on the essentials and provide a solid and dependable wireless audio experience for everyday use. If you're looking for a budget-friendly pair of wireless earbuds that simply work and last, the Sony WI-C100 are a fantastic choice.

I enjoyed using these headphones all-day most days, they have great sound for the price and the battery life is brilliant. Unfortunately, around 13 months after purchase, the left ear lost its sound. Annoyingly this was a month after the warranty period ended, so I’ll not be replacing them. I suspect if you don’t use them as heavily they’d last much longer, but it’s still disappointing.

Great battery life, good ear fit and sound great.

I’m amazed these get good reviews at all. I bought them expecting them to be similar to a previous pair but these are a new model and the quality is considerably worse The control blocks feel light, big, cheap and flimsy, the buds no longer have magnets and are fiddly and hard to insert. The wire also hangs poorly around the neck. I’ve found them completely unusable and there’s no return option here either Extremely disappointed!

Not high end for music but then no in-ears are in comparison to quality full size headphones. Where these excel are easy connectivity, easy controls and decent enough sound quality - music sounds good enough and is definitely a step up from cheaper items and for podcasts (my main use) they are excellent. Really good battery life as well. Having lost a pair I have no hesitation buying again.

3 months of light use and one side is completely broken and the other is muffled. Do not bother with these! I had an older version of these that lasted for years. Clearly Sony can no longer make a quality headphone.

Bought this the second time after losing first one. That should tell you already how much I like it It is a very nice piece of hardware. Excellent build , excellent battery backup , all day wearable. This is so much better than the totally wireless models because mic sits closer to your mouth + ear phones are connected by wire so you don't accidentally lose one ear piece. Also , the battery is powerful to last like 25 hours of listening before needing recharge. For me it translates to recharge once in 2 weeks. In other way , it also means it has enough power to drive those audio output unlike wireless ones. If you want to customize , there is an excellent sony app which allows you to fine tune music quality. Once you fine tune it with sony app you realize how powerful the bass can be on this thing. In short , extremely satisfied . I bought second piece for myself , and one more for my mother.

Piccole comode e pratiche. Qualità del suono proporzionata al prezzo, buon isolamento. Per un uso sportivo super consigliate. Bella anche la app per configurare.

Sony kulaklıkların en sevdiğim yanı kolay kolay bozulmaması, malzeme kalitesi gerçekten çok yüksek. Şarj süresi de fazlasıyla iyi; Çok memnun kaldım.

They sound great to me, but I am not an expert in sound. I need them to listen to music while I walk my dog or exercise. They are perfect for my need: good sound and volume, they completely cover the noise on the street and the cable is perfect if you want to remove from time to time and have them hanging around your neck without the need to put them in a pocket/purse all the time. Also, having the cable is better so that I don't loose one. The default size they come with is perfect but they do have the spares. For small years it fits perfectly. Great buy, very satisfied.
