I have a very specific use case (whole house audio) but wow... I'm very impressed! Here's my take on how I'm using it... Whole House Audio Project: We build our house about 11 years ago and wired it for 12 zones of audio. I have 4-wire speaker cable and CAT-5e network cable running from a central location in the basement to a single gang box in each room. Then, from the gang box, I have speaker wires running to the ceiling locations. In the 11 years we've been here, we never pulled the trigger to purchase the "traditional" system (multi-channel amps, in wall controllers, speakers, etc.) We've been quoted well over $10,000 for all 12 zones in the past. Even a DIY solution online would run nearly $4,000 without the speakers (HTD Audio's Lync system with keypads.) That's just not worth it to me. Being a Google fan, I set out to build a system using Google's Chromecast Audio devices, amplifiers, and in-ceiling speakers. I ended up purchasing this Mo-gu F900 amp for each zone in the house and it's been working perfectly! I'm at about $139 per zone and absolutely loving it! I can stream to each zone (from Pandora, Spotify, Google Play Music, I Heart Radio, podcasts, etc.) and control it from an iOS device, Android device, computer, Google Home, etc. I can have different sources streaming to different zones or group any zones together. It's incredibly flexible and easy to use. Here's the setup (per zone): 1. Google Chromecast Audio ($35) 2. Mo-gu F900 Amplifier ($31.99) 3. 82C 8-Inch In-Ceiling Speakers ($35.98 each, $72/pair - Available here on Amazon) And here's the installation details: 1. Install the in-ceiling speakers. 2. At the gang box, connect the speaker wires running to the ceiling to the 4-wire speaker wires running to the basement 3. In the basement, connect the 4-wire speaker wires to the F900 (and plug in the F900 with the included power supply). 4. Also in the basement, connect the Chromecast Audio device to the 1/8" jack on the F900. Plug in and configure the Chromecast Audio. 5. Turn the F900 on and set the volume knob about half way up. You can use the Google Home app to adjust the final volume of course. 6. In Google Home, select the Chromecast Audio device and edit the settings. Make sure you name it to the room it's located in. Also, adjust the treble and bass settings. I put both up almost all the way. The F900 can handle the wide frequency range very well. (YMMV of course so set it to your taste!) 7. Also in Google Home, set up your groups (ie: Whole house, Downstairs, Bedrooms only, etc.) You can create as many groups as you like! 8. Using an iOS, Android, or Google Home device, cast a source to the room and enjoy! Pros of the F900: * Powerful - It's driving the 8" speakers a lot better than I thought it would. Even over a long distance (>60 ft). Just make sure you use the proper gauge speaker wire if you have long distances. * Clean - We're not talking audiophile quality here but I was pleasantly surprised on how good this amp sounds. * Simple - It's a "set it and forget it" device in my solution. I plan on keeping it on all the time and I'm not too worried about it! Cons of the F900: * Size - It's actually a lot smaller than I thought it would be. Not really a bad thing but it was surprising. * Build Quality - The build quality is actually very good but the front sticker was applied a bit askew. Not a big deal though. * Hiss - When there is no audio playing, there's a VERY SLIGHT hiss that you can hear at the speaker. I mean, VERY, VERY SLIGHT. (I only heard it when I was on the ladder putting on the speaker grills. I had to have my ear closer than 12 inches away just to hear it. I can't hear it at standing height. Well, that's it. My cheap whole house audio solution is complete and a lot more flexible than I could have expected. Grand total for all 12 zones was approximately $1,670 (not including the speaker wire). The real beauty is that you don't have to do all of your zones at once. You can build it out zone by zone. (That definitely helps when you have to get spousal approval!) Hope this review helps!

I bought the 2 channel 80Wx2. I had an old bookshelf stereo system that was in a state of decline. The CD player skipped, I didn't use the dual tape deck or the radio anymore. The speakers were still good. Rather than pay a fortune for a new home sound system, I decided to trash the multiplex unit and keep the speakers. The look and size of this unit are perfect. I installed it with double sided tape on the back of one of the speakers connected the speaker wires plugged it in and turned it on. Functions well, Bluetooth connectivity is fast and easy. The power is perfect. The compatibility is great with my various sources. The quality of the sound is hands down better than when connected to the old stereo due to the Bluetooth technology. Very satisfied with this product.

Was able to test with a set of cheaper portable speakers - similar to the old cloth-covered, 3-way ones you used to find in vans. Sound is clean and decent - probably as good as one could expect from those speakers. Volume isn't overpowering but has plenty of output for sitting out back around a campfire or throwing shoes. BT connectivity was smooth and quick. One drawback - the adapter cable they provide for USB connection is terminated in USB Male, making it useless for plugging in a thumb drive. I ordered a USB F-F adapter but not sure why they bothered to send something that couldn't be used out-of-box. If you plan to use this as a USB input, either make sure your source device has a USB female port or buy the adapter along with it. Overall, a good value with or without the cable. As for BT range, I got out close to 100' line-of-sight before I started losing connectivity. I'm guessing they put the antenna inside the plastic faceplate - kinda wish they would have added a port you plug a little stinger antenna into as I would like to install this inside a weatherproof enclosure and would be nice to have an antenna I could extend outside the box and not lose BT range.

Awesome! This is a Lil Powerhouse. Does exactly what I wanted. Easy to set up with just my limited amount of audio experience, I wanted to salvage a really good set of computer speakers, to use for my Apple TV, But the ATV does not have any Audio out. Only a HDMI port. The 3rd time/try was a charm, My 1st try, was a bluetooth Receiver, no luck(very, very low output). My 2nd Try, A HDMI audio extractor with various adapters & cords. Still low output! Eventhough, I thought my Powered speakers were fairly loud, by themself. My 3rd Try Was this this amplifier. Finally, Success!! Very happy with the results! And pretty Loud, for a welcomed change. I finally figured out, I needed a Booster/Amp to Boost the signal from the hdmi port &/or Bluetooth signal. This lil Amp did the trick! My apple TV went from weak & muted TV speakers, only made worse by My 1st, 2 "weak" attemps only getting really low output, while trying to fix that with other gadgets, to a Now "It's Too Loud" remedy! very happy with the outcome! So far the bluetooth is working well (a good fix to what I thought was an overcomplicated problem). Plus I found it very easy to setup (30 min. or less). This little, inexpensive box was a great answer to what I over thought as a chaotic messy problem! I Highly reccommend to get one!

- Firstly: the Facmogu F900 pushes too much power for the speakers I used it for (two 2.25" ~9W speakers in a Bose SoundDock Series II speaker system) - I am aware, and I keep the volume on it turned down, respectively to compensate. I just liked the look and size of this amp enough to use it for my use case. - Cons: • Bootup audio jingle - One con is that, every time it boots up, it does a little audio jingle that sounds like a lullaby (can't put my finger on which lullaby it sounds like, exactly). This seems excessive - I purchased this to listen to my music, not put me to sleep with the manufacturer's lullaby music every time it powers on. - Pros: • Bluetooth - Built-in bluetooth which seems to have expected range - doing a quick test with the amp turned up, I could hear the audio begin to cut out and back in while I was about 30 feet away with 3 (interior) walls between my phone and the amp. Good overall bluetooth audio quality and connection consistency. Connects to my phone very quickly after bootup. No delays, seems made well! • Vocal mode confirmation - If a 3.5mm plug is plugged into the amp's 3.5mm jack, the amp says "AUX (ayy-yoo-ex) mode" over the attached speakers. If you unplug the 3.5mm plug from the jack, the amp says "Bluetooth mode" over the attached speakers. Both are in a cute asian voice, and are quick enough to not be obtrusive (unlike the bootup jingle). Note that when you power the device on, it reports the mode immediately after the jingle 100% of the time. - The project I used this for (updating a Bose SoundDock Series II speaker system that was getting dusty and I felt like making useful again by removing the outlet dependency and adding bluetooth capability) had the outcome of what I wanted, and this product helped make it all come together!

Absolutely awesome product. Works flawlessly in receiving a bluetooth signal from my desktop PC . The output from the F900 then goes to my wires ceiling mounted speakers. Plenty of power to annoy my wife and neighbors when I turn up the volume to 75%. Well built. Fast Delivery. (This is my second one for another location. Both work great!)

First the good. This is an amazingly small amplifier with a good quality volume knob, good quality speaker inputs, and the bluetooth synched flawlessly. I did not have bluetooth range problems mentioned by others. Now for the bad. My expectations were quite low regarding sound quality given the price, but this did not meet even those low expectations. The sound quality is simply very poor. I connected this to multiple pairs of speakers, ranging from cheap computer speakers, to $1000 Polk Audio bookshelf speakers, to $30,000 Canton Audio floor speakers. In all cases, the bass was anemic and distorted, voices jumbled, and overall quality very muddy. Compared to another tiny class T amp -- the ORB Audio Mini T -- this F900 amp is a total joke sound quality wise. I know, the ORB Audio Mini-T costs a lot more, but the comparison is remarkable. And now for the ugly -- and the reason for the 1 star review. Once again, of course I did not expect this to actually be a 100w amp. The first hint was that it is shipped with a "60 watt" power supply (more on this later). Nearly all amplifier manufacturers lie about output. If you have ever heard an honest 100 watt amp connected to fairly efficient speakers at high volume, you will understand that 100w of audio output is practically deafening. In other words, most consumers think they need hundreds of watts of output, when most need about 20-30w of clean output for anything other than a nightclub. But I digress. The "100 watt" amp being reviewed here uses less than 9 watts at full volume. I tested it with AC adaptors and with 12v and 24v DC power sources, and I could never get it to pull more than 0.75A @ 12v, or around 8 watts. It sounded horrible at those volume levels, by the way. In other words, the 100 watt specification is overstated by more than 1000%. This is a 4.5w x 4.5w amplifier, plain and simply. So why ship a 9w amp with a 60w power supply, given that a 60w power supply costs more than a 12w power supply? That is a trick question, because the manufacturer did not ship this with a 60w power supply. The power supply is labeled as providing 60w, but it actually provides much less. Based on some quick testing, it seems unstable at more than 2A, or 24w. Yet another lie from our Chinese friends behind this product. Do yourself a favor, spend a little more and get a Orb Audio Mini T or even a SMSL SA50. If you need bluetooth, get a $10 bluetooth receiver. Either amp is in a whole different league than this little piece of junk. You have been warned.

update-4 months later--CONS! 1. the popping stopped but it now disconnects every 5 minutes. 2. There is an audible hissing sometimes at all volumes. 3. The voice was cool for the first week but with BT dropping out and then reconnecting it is loud as hell and annoying! Wish they focused more on build quality than gimmicks but at this price point they made the right choice. 4. The power is almost too much since it is low quality. ** I am running Polk S15s and was running Klipsch R-41m. This amp sucks all the bass away from both speakers. I switched to my main amp (much more expensive of course) and it sounded like different speakers entirely. This is a good starter amp which is what I used it for. I could deal with the crappy sound it is pushing (most may not even notice if this is your first amp) IF IF IF the damn bluetooth wasn't so crappy and disconnecting randomly while using it. PROS: 1. it is cheap and it has decent features despite the cheap price. Overall it does what it is supposed to do less connecting to bluetooth and staying connected. It is a great starter amp if need something to get going like I did, but then plan to upgrade to something that is at least okay in terms of sound. This amp will take the life and depth from your speakers if you have decent entry level or higher.
