Sennheiser HD300 PRO
The Sennheiser HD300 PRO headphones deliver a superior monitoring experience. You’ll be impressed by the impressive ambient noise attenuation, helping you hear your audio even in noisy, loud environments. And HD 300 PRO headphones are amazingly comfortable to wear, helping to reduce the fatigue of long listening sessions. Complete with a rugged cable and 1/4″ adapter, Sennheiser HD 300 PRO headphones equip you for an outstanding sonic experience.
Measuring the truth
The HD 300 PRO works at the same level of precision that you apply to your production. To make this possible, we have pushed its acoustic properties to the boundaries of physics and recalculated them. Firstly, it’s linear frequency response. It doesn’t interpret, but rather ensures neutral transparency – the basis for good decisions. Its sound pattern remains delicate and precise in every application – across the entire spectrum.
Secondly, we have 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.
Only the sound carries weight.
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. The design of these headphones means that they are passively noise cancelling; preventing outside sound getting to the listener and also from sound escaping out of the headphones.
