Sounds definitely better. Professional ears require not only crystal-clear, high-resolution sound but also protection against unexpected peak levels. For this purpose, the Active Gard system of the HD 300 PROtect has been developed. Instead of simply cutting off peaks over 110 dB, the system adjusts the entire sound to the maximum permissible volume. This preserves the dynamics and all information. The user's concentration is further supported by additional features of these headphones, such as maximum shielding from ambient noise and a sound profile that leaves nothing to be desired in terms of clarity, differentiation, and resolution. An ergonomic design ensures that even after hours of work, only one thing matters: the sound.
