TalkThrough

TalkThrough allows direct communication with your environment, even while wearing headphones. The NoiseGard 2.0 and peak level protection remain active, and your hearing remains protected.

NoiseGard 2.0

The active noise compensation, NoiseGard 2.0, is based on the principle of deleting tones in the low frequency range (to 1 kHz) with inverse tones (phase- inverse tone). Tiny microphones record the ambient noise. NoiseGard 2.0 electronics creates a sound wave that is phase-inverted by 180° to the interfering tone

-resulting in the two sound waves almost canceling each other out.
