Facmogu F900S 160W Bluetooth 5.0 Mini Amplifier, 80Wx2 2.0CH Audio Power Amplifier, Hi-Fi Stereo Sound Digital Amp Wireless Speaker Amp Receiver w/AUX/USB/BT Input & 12V 5A Power Adapter - Silver

It is working perfectly for my use ,adding bass shakers to my sim setup

Volume control works smoothly. It clips at volume above 75% it's extremely lightweight. The power supply is a little large and makes a noticeable high pitch squealing sound. The power led isn't terribly bright or obnoxious. Build quality is pretty nice. Overall it's a pretty good value.

Used it for my bass shakers for my sim rig. This works well to power my 25 watt shakers. I liked the individual sound card. I would recommend it for anyone who is powering their sim rig.

The hardware in this device is genuinely incredible for the price point. It took no time at all for me to hook up my two speakers and get connected to play some music.HOWEVER, that is all overshadowed by the horrible implementation of the power on/bluetooth connection sounds. I have no idea who at Facmogu had the idea to make it play these sounds at max volume every time any device connected or disconnected from the bluetooth but it makes me hesitant to actually use it every morning because I know it's going to blast my ear drums out. If it was possible in any way to disable this sound (OR EVEN JUST MAKE IT NOT PLAY AT FULL VOLUME EVERY TIME) this would easily be a five star product. But at the moment I can't recommend this to anyone that values their eardrums and will be returning mine shortly.

These little amps have a built-in DAC chip/USB sound card so they can be plugged directly into PC USB ports without relying on a 3.5mm audio jack, but you can connect them this way too, as well as via Bluetooth. They are perfect for powering Dayton 30w TT25 puck transducers for things like sim racing haptics (LFE effects). I have them all over my rig. These are equivalent to the Nobsound 50w x2 version, even though they claim to be 80w x2, they don't seem any more powerful to me in comparison.

Had not had time to use it

Works great with 3 BST-2s on my racing sim using Simhub.

I have a whole home audio system, unfortunately my wife wouldn't let me run wiring to every room in the house. Now I have a need to place speakers in a children's bedroom where there is no wiring. I could do new home runs from the media closet in the basement from the amplifier all the way up to my passive speakers, which are high quality jbls, but that would cost me several hundred dollars and an afternoon of time for each bedroom. So I thought and said I'd try this amplifier. Affordable, and compact! Regrettably, these lack much punch on all parts of the spectrum. Music sounds very flat. I can get some volume, certainly enough for bedroom listening. But mostly disappointed in the quality of the sound reproduction.
