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.
