APPLICATIONS
The DT 990 PRO is an open dynamic headphone of exceptional
quality suitable for the most demanding professional and audiophile
applications. The reduced weight of the diaphragm and moving coil
result in a similar pulse characteristic as electrostatic headphones,
and in combination with a carefully tailored frequency response
offer a natural and balanced sound.
Soft ear pads and adjustable, sliding, earpieces together with a very
flexible coiled cable ensure listening comfort during extended
periods of use.
