Sennheiser HD 300 PRO Over-Ear Monitoring Headset

Share

The Sennheiser HD 300 PRO delivers a neutral, high-resolution working sound. Its huge depth of detail passes through even in the loudest of environments. Whether you are editing, playing or composing music, at the mixing desk, in a live setting or in the studio, the HD 300 PRO provides the details that you need for making sound decisions.

The HD 300 PRO works at the same level of precision that you apply to your production. To make this possible, Sennheiser pushed its acoustic properties to the boundaries of physics and recalculated them. Firstly, its linear frequency response. It doesn't interpret, but rather ensures neutral transparency. Its sound pattern remains delicate and precise in every application, across the entire spectrum.

Secondly, Sennheiser designers reduced distortion, wobbling motions and partial vibrations of the diaphragm to a minimum. Together with highly sensitive transducers, this construction guarantees powerful and 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 a remarkably natural, three-dimensional quality.

The design of the HD 300 PRO represents a smart combination of wearing comfort and ambient noise attenuation. Its circumaural, viscoelastic earpads can barely be felt even after several hours. And they provide reliable protection even against very loud ambient noise. To achieve this, we have designed the acoustic unit to be more isolated than a monitoring set has ever been. Even after sessions lasting several hours, you will detect only its sound, not its weight.
