The HD 300 PROtect closed headphone for professional monitoring in the studio and for live work. Its highly-sensitive transducers with precision diaphragms deliver high-resolution, neutral and distortion-free sound across the entire frequency
spectrum.

Viscoelastic earpads and specially sealed acoustic elements provide efficient shielding against external noise. A high level of wearing comfort is ensured by optimum pressure distribution and a recess for the fontanelle. Structure borne noise is filtered out through a coiled cable directly by the earpiece.

• Switchable ActiveGard to protect hearing for sound pressure levels above 110 dB

• Comfortable padding design allows for extended use in long wearing sessions
• Superior ambient noise attenuation in loud environments due to closed passive earcup construction
