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. PRO X line also embodies what our professional headphones have always been synonymous with: maximum wearing comfort, flexibility and professional audio quality. 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. flexibility
