Design Features

The DT 990 PRO is an open dynamic headphone. The weight of the diaphragm and moving coil of this headphone is approx. 20% compared to other current models. As a result, the DT 990 PRO offers similar pulse characteristics as electrostatic headphones. The cushion systems and light weight allow the DT 990 PRO to be used in complete comfort for long periods.


The transducers are fitted to adjustable yokes which should be positioned to fully enclose the ear. This will provide the optimum ear/speaker position for accurate sound monitoring.
The coiled cord can be extended to a maximum of 3 m and is terminated with a high-quality gold-plated mini-jack and a 1/4″ stereo jack adapter. Professional users should note that it is recommended practice that headphones are issued on an individual user basis to preclude any possible health risks.


As with any equipment which will be used in close proximity to sensitive areas of the body, it is essential that the ear pads and headband are kept clean. Use a damp cloth for cleaning using warm water only taking care not to allow any water drops into the transducers. Should it become necessary to replace the ear pads or the headband cushion, refer to “Spares and Accessories”.


When plugging our headphones into an amplifier, please make sure that the volume control is set at a minimum and is adjusted after they have been put on. It is a common phenomenon to listen to music through headphones at high levels.

The very low levels of distortion present within the DT 990 PRO can make the listening levels higher than is perceived and we would like to warn you of this so that you are able to enjoy these headphones for many years without damaging your ears.
