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!!!!!!!!

Extraordinary App. The rare extension that simply does what it promises with clean design. The audio test on backend is a real boon for people who wanted better browser sound over sound system speakers. This is a great tool.
