Be precise when it comes to fine subtleties and max SPL. HD 300 PRO enables neutral, delicate sound reproduction with high levels of wearing comfort.

• Circumaural, Sound-Isolating Design
• Highest resolution due to accurate and linear sound reproduction
• Comfortable padding design allows for extended use in long wearing sessions
• Superior ambient noise attenuation in loud environments due to closed passive earcup construction
• Perfect companion for your daily work due to long lasting materials and exchangeable cables with Sennheiser’s established system

Features

Overview:

The Sennheiser HD 300 PRO is a closed-back, circumaural pair of headphones designed for mixing and other pro audio applications. With a frequency response of 6 Hz to 25 kHz, these headphones provide clear reproduction of audio, doing so while offering up to 32 dB of passive noise-reduction. Their dynamic drivers offer a linear frequency response throughout the entire spectrum. They are constructed to remain distortion-free, even when pushed to an SPL of up to 123 dB.

The HD 300 Pro sports viscoelastic earpads that are intended to be comfortable and facilitate extended, prolonged listening sessions. The isolation of the acoustic drivers within the unit’s earcups lends to the experience, bolstering passive noise isolation as well as long-lasting comfort. The included, exchangeable cable measures 4.9′, and terminates in a 3.5mm connection. A 1/4″ adapter is included.

As meticulous as you

The newly developed HD 300 PRO delivers a neutral, high-resolution working sound. Its huge depth of detail passes through even in the loudest of environments. Irrespective of whether you are editing, playing or composing music, and regardless of whether you’re behind a drum kit, at the mixing desk, in a live setting or in the studio, the HD 300 PRO provides the details that you need for making good decisions.

Measuring the truth

The HD 300 PRO works at the same level of precision that you apply to your production. To make this possible, Sennheiser 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, they 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, Sennheiser 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.
