Sennheiser HD 300 Protect Headphones
Safe and sound. Professional ears require not only crystal-clear, high-resolution sound, but also protection from unexpected peak levels. Here, the Active Gard system of the HD 300 PROtect is on the case. Instead of simply clipping peaks above 110 dB, the system adjusts the overall sound down to the maximum permitted volume - retaining all information and dynamics in the process. Other design elements also protect the user's concentration. For example, the maximum shielding of ambient noise and a sound pattern that is everything you could want when it comes to intelligibility, differentiation or resolution. The ergonomic design guarantees that, even after hours of work, only one thing 'carries weight': the sound.
