Description of the product

Active Gard: Smart protection
The patented Active Gard technology in the HD 300 PROtect reduces signals that are too loud to a safe level, instead of just shutting down at levels above 110 dB. This allows disturbing or harmful volumes to remain distortion-free and clear, while keeping you in control of your production.

Professionally precise
HD 300 PROtect has a linear frequency response that delivers neutral, high-resolution sound. With highly sensitive transducers and precision diaphragms, it reproduces detail even at maximum volume without distortion.

Comfortable even during long use
With soft, viscoelastic ear cushions and well-balanced pressure, HD 300 PROtect is designed to be worn for long sessions without feeling uncomfortable, while effectively filtering out ambient noise.
