Trusted Studio Sound Meets High Performance
PROFESSIONAL
AUDIO QUALITYThe 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.
Wide Range of Applications Across All Playback Devices
FLEXIBILITYAnytime, 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 beyerdynamic's 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.
Built To Last
DESIGN & MATERIALSBlack, 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.
SUSTAINABILITYThe 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.
