Sennheiser HD 400 PRO Open-Back Over-Ear Headphones

Made for pro mixing, editing, and mastering, these Sennheiser open-back headphones deliver transparent, neutral sound in a comfortable, lightweight design.

When working at home or in the studio, you need your mix to sound as it does when your listeners hear it. Sennheiser HD 400 PRO headphones' 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 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.

The headphones are great. But for $249 you would think they would come with a case to store the headphones. Even cheap Sony 7640’s come with a case to protect them. Really poor choice on Sennheiser’s part not to include that protection.
