Sennheiser

Notes: Perennial favourite studio headphones from Sennheiser's extensive range. Closed-back design with an emphasis on isolation and comfort for long periods of use. Great all-rounders

Supplier notes:
The HD 280 Pro is Sennheiser's most significant closed, around-the-ear headphone to be introduced in years. Designed to exceed the demands of the professional environment, the HD 280 Pro boasts extremely robust construction combined with the sound quality, modular design and aggressive noise isolation the necessary in the field. The unique collapsible design, combined with swivelling ear cups, offers maximum flexibility in any application.

Notes: Beautiful closed-back headphones from Sennheiser, ideal for critical listening and mix applications. Not the cheapest, but sound on par with much more expensive options.

Supplier's notes:
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.

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.

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.

Supplier's Notes:
It's all in the mix.

When working at home or in the studio, you need your mix to sound as it does when your listeners hear it. The HD 400 PRO reference headphones are your everyday tool to get the job done. Its open-back design provides a natural and accurate listening experience for fine tuning your signature sound. The core of the HD 400 PRO is the 120 ohm transducer developed by Sennheiser engineers, featuring a specialized polymer blend in its diaphragm. The drive magnet offers high power while its damping system manages ventilation - this combination yields deeper bass while mitigating the distortion that otherwise impacts clarity - a difference our professional users will appreciate. This makes the HD 400 PRO a precise monitoring tool which reveals your mix in every detail. Velour earpads and a distinct lightweight design provide the comfort you need during long sessions. The robust housing endures everyday wear and tear regardless of your application, whether editing, mixing or mastering. A single-sided and coiled cable gives you the freedom to operate. For convenience, a straight cable is also included in the delivery. In addition, open ear cups and angled transducers allow for a wide and transparent soundstage, recreating the optimal listening position found in high-end recording studios. Artifacts of a confined space are a thing of the past. The HD 400 PRO is a true reliable companion for those who put quality and precision above all else.
