it can drive a 120watts of speaker into 8ohm load. sound is good and big sound stage. for the price and form factor you can't go wrong with this product. Functionality:8 out of 10 Quality:9 out of 10 Material:9 out 10I thought it's an orange color knob is included as seen in the ads that's why only 4 stars an overall rating for me.

Compact yet powerful amplifier. I paired with emotive pre amp. It gives a clean detailed and sound signature. Hearing this amp I had ordered v3 mono and waiting for receiving it.

I am an audiophile. I use this little amp over bluetooth in the kitchen with 4 ohm speakers. It sounds great! No distortion. Nice and clean. its not APTX but it works. Interface is dead simple. I do wish it would store more than 1 bluetooth pairing at a time. Also, the rear connections are very crowded.
I cant seem to get the sound to sound like I want. Bass and treble just dont get it there. Ill keep messing with it.
Nice little amp that works great. It appears to be very well made and looks cool to boot. I really like the size and the sound is really clean. I also like the 3 position toggle switch as it allows you to choose aux or Bluetooth. The Bluetooth auto-connects when selected as well.
This is the 300 watt Fosi. I pair it with old Polk studio speakers that are old but very very good. The speakers get very, very loud without distortion. For less than $100? It’s a steal for 300 watts. Don’t expect audiophile quality, you sjould pay waaaay more for that. Don’t forget banana plugs. And Walmart delivered it in 2 days whereas Amazon Prime was two weeks!
Too cute. I have several Fosi devices. They all look cool and work well. I didnt really need this amp but just had to have that VU meter.
Bought to use with two passive speakers sitting unused in my closet. Nicely designed, small amp. Supports both bluetooth and line-in audio. Pairs well with bluetooth.
