Alrighty. I was looking for a replacement for my ancient cd player/boombox that lived in a tough environment: my garage. I like some tunes while washing and waxing.This piece of gear has what I need. A closed cabinet: no worries about dusty garages.... super Bluetooth connectivity and I can even connect my iPhone's lightning port to an Aux 3.5mm in with the right cable "iSkey [Apple MFi Certified] Aux Cord for iPhone, 3.5mm Aux Cable for Car Compatible with iPhone 14 13 12 11 XS XR X 8 7 6 iPad iPod for Car Home Stereo, Speaker, Headphone, Support All iOS Version". The Bluetooth is great, and, I can also simply use the above cord to connect my iPhone to the Fosi by cable. YRMV re the cable with a different phone platform. Now I load my lossless files on the phone, connect to the Fosi, adjust volume, bass & treble and let the music roll. The Fosi has less volume sensitivity or gain using the Aux input vs Bluetooth. Adjust the volume on your phone and the Fios up for the Aux, less volume is required for the Bluetooth. The device has a small footprint....I used some spare pegboard and made a platform for the unit to sit on and have it mounted right on the wall with the rest of the tools. It's wall wart hangs easily underneath with the miracle of zip ties. It has plenty of power for my small 8 ohm speakers. Even has a remote. This could be the heart of a great desktop setup as well. Stream internet radio on your phone and feed it to the Fosi. Its got it all. Enjoy.

It’s a very small amp, the power brick is almost the same size! But it drives my 150watt 6ohm Wharfedales very nicely. Easy to use, didn’t need to read the instructions. Bluetooth range not huge, you basically have to be in the same room, but does work fine if you are in the same room. The IR remote works fine, just bare in mind it’s not Bluetooth so needs direct line of sight to the amp. Good value for money at AUD$90. Only one slight negative point and it is minor. When you adjust the bass and treble on the amp, then make adjustment on the remote the knobs on the amp don’t move to the corresponding position. The volume knob has no limit stops so doesn’t have the same issue. All in all, I would recommend for a small, single input amp.

Nachdem meine ehemalige Musikanlage im Schlafzimmer das zeitliche gesegnet hat, habe ich nach einer neuen Möglichkeit gesucht, platzsparend einen anständigen Klang für den Fernseher und gelegentliche Musikeinspielung zu finden. Dementsprechend waren die Kriterien:- Genug Leistung für ein kleines 2.0 oder 2.1 System bei moderater Lautstärke- Eine, nicht zu hohe Mindestlautstärke, um zum einschlafen auch auf sehr geringe Lautstärke Hörspiele oder Musik einzuspielen- Möglichst klein und platzsparend ums unauffällig positionieren zu können- Fernbedienung- Schnelle und zuverlässige Bluetooth Verbindung fürs HandyNach einiger Recherche habe ich mich entschieden, diesen kleinen Verstärker zu bestellen. Nun einige Monate später möchte ich mich hier zu äußern und berichten, was meine Erfahrung sind.Der kleine Verstärker hat wirklich ausreichend Leistung, um kleine bis mittelgroße Regal Lautsprecher zu betreiben. Momentan betreibe ich an ihm ein Jamo 2.1 System mit Passivem Subwoofer. Mit der klanglichen Einstellung bin ich begeistert. Auch bei höheren Lautstärken schafft, der kleine Verstärker es, mich zu begeistern. Der Fernseher ist per Chinch Kabel angeschlossen und klingt viel besser. Des weiteren bietet der Subwoofer out Anschluss eine Möglichkeit, einen aktiven Subwoofer anzuschließen. Dies hatte ich kurzzeitig ebenfalls gemacht, bin dann aber auf den passiven umgestiegen, da der aktive aufgrund des nicht so tollen Stromkreis es in diesem Altbauhaus gebrummt hat. Von dem kleinen Verstärker kann ich sagen, dass ich kein bisschen Grundrauschen höre. er ist nicht hörbar, bis man Musik spielt, sobald man diese spielt, ist man sehr zufrieden mit dem Klangergebnis. Natürlich kann man nicht die gleiche Leistung erwarten wie bei einem 300 W Receiver, jedoch ist der Verstärker für seine Größe wirklich sehr kräftig und sehr laut.Die Bluetooth Antenne, welche nach Montage hinten ein wenig nach oben ragt, ist meiner Meinung nach wirklich klasse. Auch wenn es natürlich optisch nicht so das Highlight ist, kann ich tatsächlich mit dem Handy durch den halben Garten gehen, ohne dass die Bluetooth Verbindung ruckelt oder einbricht. Das hin und her wechseln zwischen Bluetooth und Aux klappt über die Fernbedienung und über das Gerät wunderbar. Das gleiche gilt fürs an und ausschalten sowie das anpassen der Lautstärke. nicht ganz verstehen kann ich, warum die Fernbedienung auch noch Nummern Tasten hat, sowie einige weitere Tasten, die anscheinend bei diesem Gerät nicht verwendet werden. Zumindest habe ich bis jetzt nicht für alle Tasten eine Funktion gefunden. Hier wurde wahrscheinlich auch eine günstige, generische Fernbedienung zurückgegriffen, welche mehr Funktionen hat, als der Verstärker eigentlich bietet.Es kann jedoch auch sein, dass diese dafür gedacht ist, die Einspielung von USB Sticks zu steuern. Dieses Feature habe ich bis jetzt noch nicht ausprobiert.

I have this small Class D amp connected to a WiiM Mini and Polk XT15 speakers in a medium sized room. Sound is very good, lots of detail, clean mids and highs (more speaker dependent but amp helps). The remote is handly and works well. The red power on light is very small and not bright, so it would also be good in a bedroom at night, but hard to see in a bright room. I have other Fosi Audio products and am impressed with their quality and sound at their price point. Easy and cheap way to get multiple hifi systems up and running throughout the house.

You can't beat it for value or performance. I replaced a failing Cambridge Soundworks amplifier with this. Importantly; THIS kit comes with a power adapter (24v, 4.5a) of sufficient voltage and current to get max power out of the amp. 12-19 volts will not do it. Performance is significantly beyond what the Cambridge could do as to power, control, bass extension, and ability to play at max volume without sounding strained.This system was designed to run off a small 10wpc amp with 20 for the subwoofer. So, the satellites are ok but it'll absolutely overdrive the sub and bottom it out without judicious control of the sub volume. Which you can do! Because not only can you control the sub volume you can control the low pass frequency for the sub! Supposedly there's a switch inside the amp to allow the satellites to run full range but I don't see a reason to do so. High pass does not seem to vary along with the sub low pass.Sound quality is way beyond what I expected. It is not in the same class as a cheap LePai class T. It's very clean and musical. Extremely engaging to listen to especially on such a small portable system. No small Bluetooth speaker can match the impact of a real woofer and the amp drives it well.It's not going to push a monster 10" or 12" car sub. You need a sub/woofer that is fairly high efficiency as opposed to high power handling and max SPL. This is why the Cambridge system is perfect.At max volume it's a bit grainy up top and you can hear the amp go into mild dynamic compression but it never distorts unless the bass tone control is turned up. Use the sub volume instead.Bluetooth works great. No PIN pairing just scan pick and go. Must disconnect Bluetooth to use the aux input unfortunately but it's easy enough to do. Sound is not diminished that I can tell when using Bluetooth. I just got it tonight so I will update later.

For extremely reasonable price, purchased FOSI BT30C to implement a stereo system for our patio. Found unit to have plenty of power to drive Polk Atrium 5 speakers with high quality audio. Bluetooth audio worked flawlessly with every source paired, including an Amazon Echo. Unit and power adapter easily installed inside a 5"H x 9" W x 11" D cubby built into an over-sized fireplace enclosure. 120V AC duplex box installed at back of cubby, to plug in power adapter, was wired to a switched light circuit already installed near cubby. Unfortunately, if that switch is turned off with amplifier left on, speakers pop terribly... meaning amp must be turned OFF before switching off 120V supply. So, now to use the unit, we have to switch 120V on, then reach in cubby to switch on FOSI unit... which is the volume control. And, then to quit using the system, we have to reach into the cubby to turn OFF the amp so speakers won't get popped. This has proven to be a real annoyance, as knobs are quite small and placed close together. Note to FOSI Engineering... Do NOT have a power switch part of volume knob... OR fix the pop to speakers when adapter is turned off. I purchased BT30C, because it includes a sub-woofer output, which we've found really isn't needed with Polk speakers. Sub-woofer feature adds two knobs: one to control low-frequency cutoff and one for sub-volume, These two additional knobs is likely what force implementing ON/OFF with volume knob. If you're planning to implement a stereo system that has only 2 speaker (no sub-woofer), I'd advise purchasing BT20, which has a real switch for power ON/OFF. Wish I'd bough that unit instead...
