## Customer Reviews

### ⭐⭐⭐⭐⭐ GREAT VALUE!!
*by A***R on July 1, 2022*

Great little amp, big sound! Tone controls work great. Volume/pwr on-off knob is smooth. Pairing is easy. It does run warm to the touch so I cut the outlet power via light switch control when not in use (this is just me being cautious). So far I have about 3-4 hours of constant listening of the unit and zero issues. This is installed in my work shop and it's a great addition. I do follow the power off procedure of... 1) Volume knob counter clockwise to "OFF" 2) light switch to "OFF" position. I have had zero issues with audible power surge "pop" to speakers with this method. Also, I have had zero issues with pairing or unpairing of my "iPhone" to this amp. Very satisfied :)

### ⭐⭐⭐⭐⭐ Great little amp, but BT lag issue
*by J***S on February 24, 2021*

I wanted this to drive a pair of ceiling speakers that would be connected via bluetooth to my google home mini that was in my kitchen. I have a 7 zone whole house audio system being driving off google home products (speakers, google chromecast audio's, receivers with chromecast built in etc). The amp worked just fine and the BT connection was reliable, but the problem was the BT connection introduced a lag. There's a setting buried in google home to adjust for BT lag, but the lag I got off the amp would change every time I'd change tracks or started a new playlist. I'd get the living room stereo running off a chromecast audio perfectly in sync with this Fosi amp and the google mini in the kitchen using a metronome track on spotify and then as soon as I'd stop and restart the track or play an actual song the two systems would be out of sync and causing an annoying echo. Sometimes they were off so much song lyrics were an entire word ahead. It wouldn't be an issue if you were only playing this one zone, but when it's multiple zones it completely unusable if one is playing out of sync.In the end I just added another chromecast audio to this amp instead of trying to drive it with the google mini since they have a line out and it's been 100% in sync since. I don't blame the amp, which is why I still gave it a 5 star review, because doing more reading this seems like a common issue with any BT speaker connection and trying to sync it with other speakers. I've got the volume set at about 50% on the amp and it drives the ceiling speakers great, and at 1/2 volume on the amp adjusting the volume on the entire whole house system seems to stay mostly in step across the other zones. Too bad google killed the chromecast audio and no one has a similar product with a 3.5mm speaker out port.

### ⭐⭐⭐⭐ Works fine so far, but wish I had WiFi, not just Bluetooth
*by K***G on June 24, 2023*

I'll start by saying this works fine, acknowledging the range limitation of Bluetooth. I'm using this for permanently mounted outdoor speakers next to my hot tub. I figured that Bluetooth would be fine, using my phone outside with me and this unit inside driving the speakers wired through the wall. After a couple of nights in the hot tub, I realized that I would rather have more versatility than just using my phone - like wifi that I could also control via an app on my phone. The driver for this is to simultaneously control speakers throughout the house and patio, aka whole house audio....
