Beyer Dynamic DT 990 PRO
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.
