The sound quality is good and it is plenty loud even though I am using just a 9V 500mA power adapter.

Quality of music was surprisingly good for a $10 amp!

Don't expect audiophile quality but it works great.

nice quality great price.

Next time I might spend a little more and hopefully get better quality.

You wouldn't want to try to have a house thumping party with an amp like this, but the sound quality is really pretty good.

If worked - and then knob wasn't stuck inside the housing unit via poor construction and quality

Sound quality is pretty good also

Good sound quality, reasonably loud

Works great, good quality sound and cheap!!

Volume is a little staticy when turning it up or down but decent sound quality for 10$!

Good enough but not quality sound.

I appreciate the quality, the honesty, the speed of delivery and the "get exactly what is described" way this amp is sold and used

These small amplifiers had fair quality

Works great, good quality sound and cheap!!

Good sound quality, reasonably loud

Good quality item, A+Smooth Transaction!

Good quality, works as expected!

Sound quality is good and bass is reasonable for the power of the amp

Overall not very good quality.

This amp produces good sound quality and is very loud!

Bad quality

I'm no audiofile but the sound quality is terrible

But it's not, it's a "Product Review", and as a product it doesn't give a great sounds quality and it feels cheap, but it works as I'd like it

I think this amp prefers 8-16ohms for best sound quality

Poor quality

The sound quality is clean & not crackly or distorted

Super cheap, great quality.

Works fine, sound quality is tolerable

Works fine, sound quality is tolerable

It's pretty crazy what a few added watts can do to improve sound quality

The sound quality isn't perfect, and I'm not picky.

You won't be rattling windows, but you'll hear it just fine, with very reasonable "FM radio" or likely better sound quality (with decent speakers of course).

Not Audiophile quality but not any noticeable distortion at all

Now he can have good quality audio close to him, so that he can now hear.

Super cheap, great quality.

The quality of the dials are really great!

and the sound quality is great

This is not super loud, but when cranked up it still had very good sound quality.

Electronics are delicate maters need to have exact information that they works as should be

Works as it should.

Everything works as it should, but it isn't very powerful

Easy fix was to just clip of the wires on the LED and now everything works as it should, but it loses a star on the rating for that.

As one reviewer already pointed out, combining the speaker L/R outputs to facilitate a single speaker connection distorts the sound.
