Tactical Sound Control™ Technology
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 once for TSC Volume Up and
tap the left earbud twice for TSC Down.
