In this regard the sound quality, it is the level of this price range, ie it is not intended for listening to music in HIFI but more than adequate for the TV or a computer.
FM transmission poses no concern, is charged one branch and it rolls.
If dinterférence simply press the button on the right earpiece to change frequency.
My only reservation on this helmet, but it is an important subject, it is the exaggerated weight that quickly ends up annoying.
It is heavy too heavy (320 grams on the scale) even the Thomson WHP 3001 is lighter, it said.
Moreover, for eyeglass wearers, the headband too tight and can cause pain in the ears.
A good helmet, provided not to be forced to wear over an hour.
We must not neglect the comfort of a helmet but in this price range BE difficult too demanding.
