Sidetone Trimmers

-

The sidetone trimmers adjust the level of the user’s own voice in the
headphones when using full-cushion headphones. When using the speaker or
open-ear style headphones, the sidetone trimmers are adjusted to eliminate the
user’s voice from the headphones or speaker. This helps to prevent feedback.
