This product includes TSC (Tactical
Sound Control™) Technology. This is a
microphone technology that allows the
user to hear the world around them, but
always at a safe listening level. When
ambient noise breaches a safe listening
level, the microphone technology
immediately responds and attenuates to
a safe level.
Adjusting the TSC Volume is easy. Simply
tap the left earbud (2L) once for Aware
Volume Up and tap the left earbud (2L)
twice for Aware Volume Down. Left Earbud (2L)
