It does its job, and it's ok for its price, but it has many minuses: the maximum volume is a bit weak, the sound is too filtered (only the lows are heard and it gives the impression of muffled sound), I can't tell if the tone control does anything else to add a white noise and the "mix" control does absolutely nothing. It is also very sensitive to wireless interference and dubious things like when it is connected to the laptop you hear a hiss when you move your finger on the touch pad or when you are connected to the phone a hiss when you scroll on the screen.
