Sennheiser HD 300 Pro

The newly developed HD 300 PRO delivers neutral, high-quality working sound. Its great depth of detail comes through even in the noisiest of environments. Whether you're editing, performing or composing music, and whether you're behind the drum kit, at the mixing desk, live or in the studio, the HD 300 PRO gives you the details you need to create. good decisions.
The HD 300 PRO works at the level of precision you apply to your production. To make this possible, we pushed its acoustic properties to the limits of physics and recalculated them. The first is the linear frequency response. It does not interpret, but provides neutral transparency - the basis for good decisions. Its sound sample remains refined and accurate in every application - across the spectrum.
Second, we've minimized diaphragm distortion, wobbles, and partial vibrations. 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 very natural, three-dimensional quality.
The design of the HD 300 PRO represents a smart combination of comfort and ambient noise reduction. Its round, viscoelastic earcups are barely noticeable even after a few hours. And they provide reliable protection against even very high ambient noise. To achieve this, we designed the acoustic unit to be more isolated from the monitoring suite. Even after several hours of sessions, you will only detect its sound, not its weight.
