Small but mighty
As an person who’s used to high-end tube amps and large receivers, I wasn’t expecting much from such a small, affordable amp.No, it’s not going to replace your multi thousand $$$ boutique amp for critical audiophile listening or bragging rights, but for 99% of the population or normal TV, movie, game and music listening it’s awesome.I loved it so much that I ended up buying a second one.This little powerhouse easily drives my JBLs and KEF LS50 speakers to impressive volume levels with crystal-clear clarity. It’s perfect for my living room TV setup.The Bluetooth feature works flawlessly. I also appreciate that it comes with a remote. For the price, this amp is a steal. If you’re looking for a compact, budget-friendly amp that still delivers excellent performance, I highly recommend it!

Very compact, and simplistic. Really like it.
So far, this little device has performed above what I had expected. It is very simple, having only volume, treble, bass, off/on buttons/switch.I have it connected to a vintage set of 8 ohm, Cerwin Vega D3’s. I am quite impressed at this point. Bluetooth maintains connectivity throughout my house. I have not experienced it connecting to other Bluetooth devices, as I have read in other reviews. It sounds good, not high fidelity stuff, but good. I may consider another unit for my front porch, but want to give it a little more time. As for now, yeah, it’s a great device.

Crazy good for the price!
Simple to hook to my bookshelfs (Wharfedale Diamonds) and Cambridge CD player. Amp is little; about the size of two packs of cigs. Excellent fit and finish. Doesn’t have the punch of a 40 lb amp but presents the music very nicely. 25% volume is plenty for me; 33% is about max in the family room I have it set up in. Excels on simple music like Japanese flute, cello, guitar, vocals; gets a bit congested on hard rock and similar but I bought it for the former not the latter, and my bookshelfs do best with the same. Bluetooth connected instantly and sounds superb. I’m very pleased with this purchase.

great little amp. does the job nicely
i got this to replace the final stage on the sony amp that blew it’s left side. the sony still works as a preamp and switcher for the turntable, tv and music streamer i have so i didn’t have to redo a lot of wiring. all i had to do was run a line from the tape-out on the amp and move the speaker wires to this little guy. all my controls and remotes stayed the same. nice bonus is i now also have bluetooth. it’s not as powerful as my original amp and you can’t drive it as hard; ive a feeling if you do, something will blow as the components are rather small. it happened on another, similarly built amp. the sound quality is adequate, esp in this age of earbuds. my wife doesn’t notice but i can definately tell there is a midrange bias, even with the tone controls. still, it’s good for it’s size.one thing i really like is the bluetooth addition. the sound quality is good and there is very little spurious noise. it is a preferential connection so it will override anything coming in from the AUX inputs. i wish there was a button to switch but as is, just turning off the bluetooth on your phone will cause it to automatically switch back.overall, it’s a good little unit. i wish it were closer to a $60 price point but build quality seems good and sound quality overall is great for this little guy. i’ll probably buy another one to use as a portable outdoor entertainment like another reviewer did.

This is an excellent product
TL;DR: This works exactly as it should. Great piece of equipment is such a tiny form factorI’ve been meaning to setup a more permanent outdoor speaker solution to my backyard and was going to go with the old fashioned “run 200 feet of speaker cable” because the high receiver I bought was pretty far away and I was going to use Zone 2 for the speakers. But this little package came up on my searches and it was exactly what I wanted and more. There is an area in the backyard that we set up outdoor movies at and I use a portable speaker for sound. Instead it dawned on me that not only can i stream music from any source with this bluetooth connection to this device, I can also double up and use it for outdoor movies if I place them correctly. Well I found an outdoor telephone jack and indoor jack and I was able to run audio cable outside through those openings which were right next to where I would put the movie screen. So I was able to put two outdoor speakers in a place so that it can provide sound for movies AND they are in a general area that I can stream/play music for the backyard in general. No need to wire anything from the receiver and eliminates the need to bring out a boombox outdoor speaker for movies.What I was really happy about is how fast and solid the bluetooth connection is. I use an old laptop for streaming music and store all my ripped CDs. I thought I was going to have to hardwire the laptop to this Fosi amp because the laptop is like six years old. After a little work and trial and error, I finally figured it out and it works. The first time the laptop had a hard time finding it but now that it is in the list of known devices, it connects flawlessly. I tried iphones, tables, etc. and all of the newer devices find it with no problems. Even my echo show found it and its about 40 feet away in another room. Movies sound great, have my Lounge music running at night and I’m so happy about this setup. And, going back to my resistance to running cable, I only need 30 feet of outdoor cable for both speakers so it was convenience too.Highly recommend this product: very inexpensive, does exactly what it is supposed to and greatly enhances the flexibility of what you can do.

Solid Value for Money
Been using this for about a year now and continues to work great. Speaker cable got loose at the back and lead me to believe it was dying. Not the case, tightened it up and it still works just fine. Audio quality is actually really good paired with Fluance Studio Monitors. Bluetooth has been nothing but reliable. Seeing some cheaper options on the market now like Pyle. Will likely try that one next even though this performs well.

I have been using this amplifier for a month now. It is working without any issues. The build quality of the amp as well as the adapter is very good. Looks tiny besides my old amp.My Old amp stopped working so am using this amplifier as an temporary alternative to power a set of Solidaire SS100 bookshelf speakers with a 12-inch woofer, a 4-inch midrange, and a 1-inch horn tweeter with impedance of 8 Ohms.Bluetooth range is also good. Comparable to my existing Logitech Bluetooth adapters.I have noticed it does not get warm on long usage when listening at acceptable volumes at home.The audio quality is flat and commendable in the Fosi amp, but I seem to miss the warmth my old Solidaire AS1200D amp provided. So, I tend to boost the lows and mids from the equalizer to get the desired effects.My decision on buying this over Aimyia amp was swayed because FOSI provide a warranty on their product, but Aimyia brand amps have no such mention in their listings.

Je suis très impressionné par la qualité de ce produit. L’ampli ne produit quasiment pas de souffle. Il ne chauffe pas (c’est la magie de la technologie “classe D”). Il est petit, compact, facile à brancher, simple et très bien conçu. Largement meilleur que nos amplis d’autrefois (de “classe AB”) dits “HiFi”, qu’on aura pu acheter dans les années 1970 à 2000. Le prix est très modeste. Rapport qualité/prix exceptionnel.

Sarà che va a pilotare delle polk xt15 ma l’amp conterà pure qualcosa nella qualità e per quanto è costato ha cambiato totalmente la prospettiva e le modalità di ascolto, potenza e qualità ad un prezzo accessibilissimo. Se come me siete entrati da poco nel mondo hi-fi non credo ci sia scelta migliore per iniziare.
