Closed Studio Headphones
SENNHEISER HD 300 PROTECT are closed studio headphones that combine advanced peak level protection with incredibly detailed sound and exceptional comfort.
The patented ActiveGard technology of the SENNHEISER HD 300 PROTECT does not simply switch off at peak levels above 110 dB, but rather reduces overly loud signals to a safe level. Previously harmful or dangerous volumes therefore remain distortion-free and clear, and production control is maintained at all times.
The SENNHEISER HD 300 PROTECT not only meets the EC's European noise directive on industrial safety and noise control, but also safeguards the hearing and presence of mind of all production personnel, even in the event of major or minor surprises.
The acoustics of the SENNHEISER HD 300 PROTECT are systematically adapted to the needs of professional use. Its linear frequency response provides a neutral, high-resolution sound. With its highly sensitive transducers and precision diaphragms, the SENNHEISER HD 300 PROTECT observes a phenomenal depth of detail that reproduces, even at maximum volumes, crystal-clear sound without distortion.
Professionals often wear headphones for several hours, which is why the SENNHEISER HD 300 PROTECT has been designed with particularly soft viscoelastic ear pads that also filter out ambient noise and finely balanced pressure distribution.
