It works!!!!! also it does not seem to be a scrapper extension like most the chrome ones

With this you can boost bass and volume.

A la place de On Off il faudrait un indicateur plus facile a comprendre .A part cela l'extension est bien

Great addon! For me without amplifier it's very useful to make preamp.

У меня отлично работает совместно с блютус наушниками. Другим средством частотный диапазон отрегулировать невозможно.

Excellent. Works exactly as expected; perhaps even better. Thank you!

does exactly what it says on the tin and does it well with minimal resource usage.

Very nice!!!!!!!!
