The sound is the best I have owned

Pretty good sound with a 19v laptop ps

Very rich and dynamic sound through all sound levels

Insane power and sound for such a small device

I also had to change a resistor inside the unit two Lower the loud popping sounds that it makes during power on and off

Convenient and really good sound for my projects!!!

Good sound

Sound is not great

There is a loud buzzing sound when the music is not playing

Sometimes it sparks and makes a loud popping sound like the speaker's going to blow

Aside from that the sound and quality this board puts out is excellent and worth every dollar.

Great sound.

It also makes good crisp sound come out of some older speakers that aren't the best quality

The sound was loud, clear and without any imperfections.

Great, loud, sound for cheap, cheap, cheap...

Great, loud, sound for cheap, cheap, cheap...

i like it, sound excellent, is a great product

The sound was loud, clear and without any imperfections.

Sound is great even with crappy speakers

converted my old broken BOSE sound dock in 10 minutes to Bluetooth, awesome sound, fits perfectly inside of the cabinet, just rout power trough the back and control it from your phone or tablet

Great sound for the price

Excellent sound in a small package

Mediocre sounds, minor buzz

Connection is fast and the sound it delivers is great

sony was not perfect , lacked some highs and medium sounds, frequencies

For a $15 amplifier the sound is good.

not the cleanest sound, but for the money it's fine

" suround sound style cube speakers, a 12" sub (sounded good), to some mid price Dayton bookshelf speakers (also

For $16 (at the time of this writing), the board is a steal: plenty of volume, clean sound and easy installation.

There is hum/static sound when the music plays... pause or stop the music and the static will also stop.

great sound so far

The sound is excellent if you ignore the loud startup noise

They work as intended, sadly the sound it emits while buttons or on an off are annoying( too high)

It delivered excellent sound.

Sound is powerful but with lots of noise

good sound

So I purchased another TDA7492 amplifier from Douk - nice clean sound again.
