DESCRIPTION
The DT 990 is an open dynamic headphone of exceptional quality
and suitable for all music styles; whether you are into pop, classical
or jazz, the DT 990’s will deliver the true sound as it was originally
intended to. 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
provide a natural and balanced sound. Soft ear and headband
pads together with a single-sided cable ensure listening comfort
during extended periods of use.
The DT 990 is still manufactured in Germany providing an excellent
quality.
