6. Please be aware that using earphones will affect your ability

keep your earphone volume level reasonably low to minimize
this effect.
When Silent Mode is selected, voices are collected from the
Bone Conduction Mic. The sensor (on the H501 face with oval
circle) should be positioned near the throat in order to have the
best quality. The best position for voice collection is 4-5cm
above Adam’s apple on either side of the throat. Clip the H501
on your helmet strip, allow it to rest comfortably between your
throat and helmet stripe. Of course, you can also clip the H501
onto the collar of your shirt, using your hand to touch your throat
while talking.
