The Sennheiser HD 300 PRO headphones offers neutral, high-resolution working sound. Its enormous depth of detail emerges even in the noisiest environments. Regardless of whether you are editing, playing or composing music, and whether you are behind a drum kit, at the mixing desk, in a live environment or in the studio, the HD 300 PRO provides the detail you need to make good decisions. We have pushed the HD 300 PRO’s acoustic properties to the limits of physics and recalculated them. First of all, the frequency response is linear. It does not interpret, but provides neutral transparency, the basis for good decisions. Its sound pattern remains delicate and precise in every application, across the entire spectrum. Secondly, we have minimised distortion, oscillating movements and partial vibrations of the diaphragm. Together with the highly sensitive transducers, this design ensures powerful, distortion-free reproduction even at high sound pressure levels. Not to mention the recalculated air volumes in front of the ear. The HD 300 PRO gives the sound an extraordinarily natural three-dimensional quality. The design of the HD 300 PRO headphones is an intelligent combination of comfort and attenuation of ambient noise. Its viscoelastic circumaural ear pads are barely noticeable even after many hours. And they provide reliable protection even against very loud ambient noise. To achieve this, we have designed the acoustic unit so that it is more isolated than a monitoring set has ever been. Even after sessions of several hours, only its sound can be heard, not its weight.
