2. DESIGN FEATURES
DT 250 / DT 252
The DT 250 / DT 252 is a closed dynamic headphone oering
excellent ambient noise isolation making it suitable for all kinds
of applica tions in broadcaing and recording udios. The head-
band and earphone cushioning syems have been carefully
designed for maximum comfo and unobtrusive yle. The
poweul neodymium magnet syem provides high-fidelity
reproduction and a balanced sound. The andard impedance is
80 Ω. Fuhermore, versions with 250 Ω syems are available. The
connecting cables to the ear monitors run safely in the headband
and the main connecting cable is terminated on one side with a
multi-pin connector.
