PROFESSIONAL AUDIO QUALITY 
Trusted studio sound meets high performance

The STELLAR.45 sound transducer, developed and produced in Heilbronn, Germany, delivers that proven beyerdynamic sound at previously unattained levels of studio-headphones-class performance. This is down to the neodymium ring magnet as well as copper-clad high-tech wire. The trade-off between electrical conductivity and the weight of the wire is unique. In combination with the newly developed three-layer speaker diaphragm featuring integrated damping layer, this has created a highly efficient driver system that performs superbly on all playback devices.

The innovative membrane structure controls the axial motion of the voice coil and ensures that it remains securely positioned in the magnet gap even during high oscillations. Another benefit is vast and natural frequency response. The fast response of the transducer and the detailed transient response, produced by the low coil weight, create a sound that is always reliable and distortion free even at high sound pressure levels.

FLEXIBILITY
Wide range of applications on all playback devices

Anytime, anywhere - the wide range of applications offered by the new PRO X line unleashes your creativity. Be it on an audio interface, laptop, tablet or mobile phone: Thanks to our new high-performance STELLAR.45 driver, the PRO X headphones with an impedance of 48 ohms reproduce sound at volume and power to familiar levels of studio quality - on all playback devices. The cable concept is also demonstrably suitable for everyday use: the removable mini-XLR cable can be swapped out as required to be replaced with cables that have different lengths or feature other connectivity options.

SUPERB WEARING COMFORT
Tailored fit for extra-long sessions

The new PRO X line also embodies what our professional headphones have always been synonymous with: maximum wearing comfort. The robust spring steel headband design assures the over-ear headphones provide a secure fit and ensures durability. The supple velour ear pads are soft to the touch, as you would expect, and guarantee superior ventilation. The headband ergonomically adapts to the shape of the wearer’s head with the aid of soft memory foam and, like the ear pads, can be replaced if required.

DESIGN & MATERIALS
Built to last, featuring a sleek, robust design

Black, minimalist and reduced to the essentials. In a word: PRO. 

As far as the design of and materials used in the PRO?X line are concerned, attention was paid to the resilience of all components: metal headband, GRP components, a robust mini-XLR connector and hard-wearing cable. This means you are geared up on a daily basis for any professional application.

SUSTAINABILITY
Sustainable headphones - made in Germany

The new PRO X line headphones have been designed for daily use in challenging conditions. This is why they are handmade in Germany using premium quality materials. If required, nearly all the headphones’ components can be replaced, turning these headphones into an investment that makes sense for every creator.
