quality, the microphone boom has to be adjusted to the shape of 
your face.

angle of the microphone boom.
왘 Adjust the microphone boom: 
You can change the length of 
the microphone boom by 
bending it. Due to the omni-
directional pick-up pattern of 
the Ear

distance of 2 to 3 cm between 
microphone and mouth.

CAUTION! Damage to the microphone boom
The microphone boom can break or be impaired in 
its function when the bend diameter is too small 
(<
 2 cm) or when you bend it close to the micro-
phone. Also avoid frequent alternate bendings. If 
the microphone boom breaks, you can be injured.
