PROFESSIONAL AUDIO QUALITY: Trusted sound & high performance; the new STELLAR.45 driver.

Developed in Heilbronn Germany, the new STELLAR.45 sound transducer delivers that proven beyerdynamic sound, but at a previously unattained level of performance, for such an all-rounder headphone. Responsible for this are the neodymium ring magnet and a copper­plated aluminum coil which, in combination with the newly developed membrane featuring integrated attenuation, form a highly efficient 48 Ω driver system that performs superbly on all playback devices.

Another benefit is its comprehensive, detailed and natural frequency response. Very short time lags as well as a detailed transient response ensure a constantly dependable sound, even at high levels. The fast response of the transducer and the detailed transient response, produced by the low coil weight, create a sound that is always reliable even at high sound pressure levels.

In addition, due to our newly developed PRO X absorber pads made out of acoustic damping materials that are placed in front of each driver, the treble frequencies are not only very balanced and smooth, but still very detailed. This ensures extra-long listening sessions without missing any details in the sound.

The result are headphones that excite you, and help you excite others with your music.

FLEXIBILITY & SUSTAINABILITY: A wide range of applications on all playback devices, time and time again ensures no limits to your creativity.

Anytime, anywhere - the STELLAR.45 driver, developed in Heilbronn Germany, reproduces the best studio-quality sound loudly and powerfully on all playback devices. Whether on an audio interface, laptop, tablet or mobile phone, there are no limits to your creativity or workflow. The cable concept is also suitable for everyday use: the removable mini-XLR cable can be swapped out as required to be replaced with cables that have different lengths. Sustainable headphones – hand made in Germany using premium robust quality materials; almost all of the headphones' components can be replaced, therefore these headphones are an investment that makes sense for every user.

COMFORT & DURABILITY: Made in Germany from the highest quality materials.

The rugged spring steel headband construction gives the over-ear headphones a secure fit and ensures durability over time. The supple velour ear pads are soft to touch, as you would expect, and ensure comfortable air circulation. Thanks to soft memory foam, the headband adapts ergonomically to the shape of the head and, like the ear pads, it can be replaced when necessary. The robust and high-quality materials used to make these headphones in Germany go hand in hand when it comes to delivering both comfort and durability for years to come.
