Studio Reference Headphones
Sennheiser - HD 400 Pro

Sennheiser - HD 400 Pro

'Its all in the mix'No matter if you’re working at home or in the studio, it’s imperative your mix sounds as it does when your listeners hear it. Sennheiser’s HD 400 PRO reference headphones are your everyday tool to get this job done, each and every time. Thanks to its open back design, the HD 400 PRO delivers a natural and precision listening experience for fine tuning your signature sound.

At the heart of the HD 400 PRO is the 120-ohm transducer developed by Sennheiser’s very own engineers, featuring a specialised polymer blend in the diaphragm. The drive magnet offers impressive high power while its damping system takes care of ventilation – this clever combination yields deeper bass whilst mitigating the distortion which otherwise impacts clarity – a key difference which pro users will be sure to appreciate.

tough & robust housingVelour 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.

Sennheiser HD 400 Pro - Open Back Studio Headphones
Good for Mixing?

Sennheiser's HD 400 Pro is a new headphone designed for studio mix work, with price tag just over £200. Tom gets them analysed and compares them to the HD 600 Studio workhorse of the past couple of decades.

We forgot to mention these are 120 Ohm and do benefit from a decent headphone amp, Something like the ifi Zen Can or Topping L20 / A30 Pro would do really well for a modest investment if your interface hasn't got enough power.
