SafeMax™ Technology
ISOtunes® Sport DEFY Slim Basic incorporates SafeMax™
Technology, therefore its volume output has been limited to 85
decibels. ISOtunes® Sport devices with SafeMax™ Technology are

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.
This feature automatically turns on when the product turns on.
Adjusting the TSC volume is easy: simply turn the large dial up or
down.
