Fosi Audio BT10A Bluetooth 5.0 Amplifier Stereo Power Amplifier, 2 Channel Class D Mini Hi-Fi Integrated TPA3116 Audio Amp, for Home Speakers 50W x 2, with 19V 4.74A UK Power Supply

Arrived in a fair sized box - then you open it and go 'No way'. It's tiny, maybe as big as 2 Nurofen packets on top of each other. Is this gonna make any sound at all? (I'm used to 19 inch Cambridge amps etc). Well flippin eck, it does. I was gonna use it to power the sound on my tv, a Hisense, into Gale bookshelf speakers, which can sound amazing. All you do is attach the speaker cable, then the tv and the Fosi amp found each other straight away via Bluetooth...and boom. Big sound, happily supplying the speakers with all they needed. And it sounds great! I just set the unit's volume to 12 o'clock and control the level via the tv remote, never touch it. For £60 this thing is startlingly good, and let's be honest cheap as chips.

Like many others, I was skeptical at first—there's no way this tiny unit could deliver good sound or have enough power to drive floor-standing speakers, right? Well, I couldn’t have been more wrong! I bought this to replace an old, bulky multi-channel amp that had finally given up after years of service in my son's setup. We wanted something smaller, more efficient, and after plenty of research (and a bit of bravery), I decided to give this a shot. When it arrived, we set it up, connected everything, and placed it neatly under his monitor. The results? Absolutely incredible. The sound is rich and well-balanced, with deep, punchy bass and crisp, clear highs. Even with floor-standing speakers, this little amp delivers serious power! To top it off, the Bluetooth works flawlessly, making it even more versatile. For the size and price, this is hands down one of the best audio purchases I’ve made. Highly recommended!

I bought this to power some Wharfedale Diamond 9's in our spare room. I am extremely pleased with this little amp. I only set it up yesterday so it's not had a great deal of use, but the sound really is impressive for the price and size of this little amp. I've streamed from my phone, and from an Alexa sitting in the same room. The tone levels around half way were about perfect for the front-ported Diamond 9's close to the rear wall. Clear, low distortion, precise, and capable of decent levels for my purpose.

Just delivered, on time, lashed up, BT connected, music playing. Blown away by the quality into Mission 760s, goid tight bass, sweet treble, solid midrange, decent stereo imaging, loud enough for my living room on about 60% volume. How can something so small sound like this? Build quality seems fine. When it's been in use for a year or so, I'll give it 5*!

This is an amazing amplifier for its very small size. I have it connected to 2 x TEAC 8 ohm speakers, and my sound input is from a portable cd player. The sound is very good and with the added bass and treble control it gives me the sound I want. I have only turned the volume up halfway, and it is very powerful (don't want to annoy the neighbours!!) One small niggle is the closeness of these two knobs - which with my big fingers is a slight challenge, but it does not put me off the excellent sound output and style of the amplifier. I have yet to try the Bluetooth facility, using my mobile and tablet, but I'm sure it will be just as good. User manual is very easy to use and understand. Arrived well packed and on time. Can recommend 👌

I wanted to create a budget friendly Hi-fi setup for my dining room. I got hold of some nice 120watt 6ohm Denon speakers from Facebook Marketplace for a few quid. Once hooked up to this I have to admit I am impressed. This tiny amp drives these speakers with plenty off room left for volumes I'd only dare go to in my younger years. The sound is rich and warm (though of course milage with vary depending what you hook up to). As I type this I am streaming sounds of the 70's from radio 2 app on my phone via Bluetooth and I couldn't ask for a better Hi-fi sound. The range is great, the sound stage is great and the power is more than enough. I also have an amazon basic vertical CD player hooked up and these sound wonderful too. My wife was skeptical at first "but we have a Google thing". Yeah, no... There is no match for real Hi-fi and I am very happy to report this is as real as it gets. I have a dedicated Denon amp and setup in the other room but I think I actually prefer my new setup which cost a quarter of the price! I hope it lasts but I have no reason to believe not. The amp is small but feels quality with an all metal construction. I hope to be using this for many years to come. Overall I would not hesitate to recommend Fossi audio to anyone.

We wanted to power some outdoor speakers (Adastra 4") on to a patio area, so we hitched this amp up to an Apple AirPort to stream music from the house out to an outbuilding where we've placed the Amp. There's no remote, but a simple volume control and easy fittings for the AirPort / other input and speakers, plus built-in Bluetooth so we have the choice of either linking to music playing in the house extended outdoors or just to BT from a mobile device when we're just sat out on the patio. It's very easy to connect the BT and so far it's been very stable from about 4 - 5m away through a wall. There's little functionality to this Amp, just switch it on, play something connected to it or connect by BT and play. Very easy to set-up & use and the sound seems clear and just what we wanted. We've not yet had it turned up to 'party' volume and infrequently ever will, but for reasonable, don't upset the neighbours, levels it's more than adequate and it's no where near its maximum. Overall - we're very happy with our purchase, esp. with the built-in Bluetooth.

Just got the most powerful range and I recommended to anyone

We used this great little box to replace a broken home stereo. Works perfect for what we needed. Pros: The sound is perfect for streaming movies, podcasts, talk radio, and background music. The blue tooth connection is nice so any of us can connect to it from our devices. Having treble and bass settings gives us the sound we want to hear. The connectors at the back handle bare wires easily. No need to get special connectors. Cons: The blue tooth connection is automatic. It means that if we want to play a movie from the computer which is direct connected, we have to all turn off blue tooth from our devices. I don't think this device is for anyone who wants to really play quality music at any decent volume. E.g. my daughter plays the Attack on Titan theme songs a lot, which is like playing 2 symphonies and Rush at the same time, and with so much going on, the music becomes indecipherable. It could be my speakers, but there was nothing I could to make the music sound crisp. Other reviews might help to straighten this out. I wish I didn't buy special connectors. :-/

What a great product. I took a couple of months to finally get around to researching the options for a wireless amp that I could mate to my old AIWA twin 40 watt speakers which I retained after throwing out the ancient triple CD player deck they came with. I first came across the Fosi (blue) mini amp which didn't have bluetooth but after a little more research found this unit which is only 10 bucks more ... as I wanted to be able to connect my phone or laptop quickly with no wires this was the best option. The device came quickly several days ahead of the original delivery estimate so that was cool, I unboxed it. Great quality you can feel the sturdiness of the metal, well crafted. The toggle switch is solid, the volume dial is smooth...though if it had a larger diameter it would allow some more volume control fidelity. Getting it up and working was a literal 4 minute affair. I connected the speakers using the twist connectors on the back, I plugged the adapter into the amp then into the wall (as they insist you do). Then powered it on...as described the blue tooth was broadcasting and my phone connected, an audible bump attends each connection disconnection. I set up the device as a trusted blue tooth on my phone which would allow it to auto connect when my phone is in proximity so I don't have to actively connect it so long as my blue tooth is on my phone which is super convenient. I started playing various audio, I played some high quality mp3's and it was great to hear those speakers come to life for the first time with a high quality amp that could push them to their limits (this amp is 50w per channel so I need to be careful). I also played some youtube videos which sound so much better coming through full powerful speakers (which I have on the ground so there is the bass effect). Edit: Since connecting my phone I also have mated the device with no issues with my laptop...as I am often at home with the laptop it serves as a better streaming source to the device ...I could in theory also use my nexus 9 for this. The sound coming from movies and videos played on youtube is rich and distinct, extremely happy with this as I am about to purchase a large HD screen that I will also be casting sound to this speaker set up through. Needless to say they just work, really great I am considering buying another one and a pair of new speakers just to use in my other room, I considered at first getting a Google chrome Audio because it allows connection through wifi but I would still have had to buy a mini amp to drive these speakers so decided to get this since blue tooth has pretty good range and often better quality than wifi (particularly as quality doesn't degrade with device connections as with this it is a dedicated connection) and like I said this version of the mini amp was only 10 bucks more than the non blue tooth version. Highly recommended.

Heel erg mooie versterker, straalt kwaliteit uit en krijgt goede reviews. Ik gebruik 'm puur als bluetooth ontvanger met bijbehorende versterker functie. Werkt heel goed, koppelt vlot met de BT bron. Is een onwaarschijnlijk kleine behuizing maar produceert een goed geluid. Doet alles volgens specificatie - als je meer power nodig hebt is er een een 20W versie, maar die is natuurlijk duurder!

Por el precio el sonido es excelente !

Ho acquistato il Fosi Audio BT10A per dare nuova vita a una coppia di casse passive da 50W + 50W di un vecchio stereo che ormai non emetteva più alcun suono. Basandomi sulle tante recensioni positive, ho deciso di provarlo e ne sono rimasto estremamente soddisfatto. Cosa mi ha colpito di più: • Dimensioni incredibili: Quando dico che è compatto, intendo dire che occupa esattamente lo spazio del palmo di una mano. È un cubetto solido che sparisce sulla scrivania o in libreria, ma che racchiude una tecnologia sorprendente. • Qualità del suono eccellente: Il suono è pulito e cristallino. La gestione dei toni acuti e dei bassi è ottima, permettendo di personalizzare l'ascolto in base al genere musicale. • Zero rumore di fondo: Un aspetto fondamentale per me è che non emette alcun fruscio o rumore nelle casse quando il volume è attivo ma non c’è audio in riproduzione. Resta perfettamente silenzioso. • Potenza reale: Nonostante la grandezza, spinge le mie casse da 50W con una forza e una pulizia incredibili. Non fatica mai, anche a volumi sostenuti. • Affidabilità H24: Lo lascio sempre acceso giorno e notte e non ha mai dato problemi di surriscaldamento o cali di prestazione. È un mulo! Considerazioni finali: L'unica piccola mancanza è il telecomando, ma è una scelta che ho fatto consapevolmente per risparmiare sul prezzo d'acquisto. Modelli con telecomando esistono, ma costano di più, e per l'uso che ne faccio (collegamento Bluetooth rapido e set-up fisso) questo modello è assolutamente perfetto. In sintesi: Se avete delle buone casse da recuperare e non volete un amplificatore ingombrante, questo Fosi Audio è la scelta migliore che possiate fare. Qualità professionale in un formato tascabile!
