HD 300 PROtect
Professionals' ears need not only crystal clear high resolution sound, but also protection from unexpected level spikes. Here, the ActiveGard system of the HD 300 PROtect is on the housing. Instead of simply cutting peaks above 110 dB, the system adjusts the overall sound to the maximum allowable volume - a process that retains all information and all dynamics. Other design elements also protect user focus. For example, the maximum shielding against ambient noise and a sound diagram that represents everything you could want in terms of intelligibility, differentiation and resolution. The ergonomic design ensures that even after hours of work, the only "weight" felt is that of sound.
