Remarks

Other models of the same series:

The DT990 is one of the few headphones that have been around for very many years. The model first came out as a 600 ohm impedance model and then was later offered alternatively as a 250 ohm model as well as being further developed as the DT990 pro or DT990 Manufaktur, without taking the base model out of the range.

Also the spare parts supply for the models of the first years is still given by Beyerdynamic (exemplary !), so that you can refresh your "old" high-end top model. http://www.beyerdynamic.de/shop/hah/spareparts.html?kopfhoerermodell=566
