Pass Thru Mode allows you to hear equally with both ears when not on a phone call. To activate Pass Thru Mode select ON. To de-activate it, select OFF or turn off the headset.

Pass Thru Mode allows you to select 'Focused Listening' or 'Surround Listening'. Focused Listening will focus on the talker in front of you. Surround Listening will give you 360° surround sound. The default setting is Surround. The next time Pass Thru Mode is activated, the setting will automatically be switched back to Surround Listening.
