DampingDAMPING MATERIAL No Vibration - Just Sound
Listening to favorite music is most enjoyable if there is no disturbing noise around.
Unfortunately, in-car environments consist of a wide range of materials causing a lot of annoying noises.
Especially large scaled body parts tend to vibrate and affect the audio reproduction of the car speakers in a negative way.
GROUND ZERO damping materials offer high efficient noise proofing.
They reduce vibration, increase bass response as well as dynamics and by that ensure precise audio reproduction.
There are particular products for each neuralgic car part influencing the sound quality available.
If you would like to enjoy the typical GROUND ZERO sound not only in your vehicle, you may choose one of the two headphones.
Both of them delivering a distinctive bass response and the dynamic sound character.
