The Sennheiser HD 300 PROtect headphones combine detailed audio monitoring with essential hearing protection, making them ideal for audio engineers, broadcasters, and musicians who work in demanding environments with high sound pressure levels. They feature a highly sensitive transducer that delivers a linear frequency response from 6 Hz to 25 kHz, ensuring transparent and analytical sound reproduction for accurate monitoring. The key feature of the HD 300 PROtect is Sennheiser's switchable ActiveGard technology, which automatically protects the listener from sudden, extreme sound bursts (over 110 dB SPL) without interrupting the audio signal. The headphones also offer excellent passive noise attenuation of up to 32 dB, isolating the user from ambient noise for focused listening.

Designed for comfort during long sessions, they feature soft, viscoelastic earpads that are easily replaceable, along with a rugged, foldable design for portability. The included detachable, single-sided cable minimizes tangles and ensures freedom of movement.
