DT 790 | Headset with Dynamic Microphone for Applications in Loud Environments (closed) (80 Ohm)
Beyerdynamic DT 790 | Headset with Dynamic Microphone for Applications in Loud Environments (closed) (80 Ohm)
The DT 790 is the perfect combination of the closed studio reference headphone DT 770 M, the high-quality microphone of the DT 290 and a new pivoting, gooseneck microphone boom. This headset is especially developed for Intercom purposes in very loud environments like concerts, sporting event etc., where isolation of ambient noise, durability and wearing comfort are of prime importance.
The powerful headphone-systems with a frequency response of 5 – 30.000 Hz, provide a perfectly balanced sound characteristic. The sound insulating housing and soft-skin ear pads cause superb isolation from ambient noise and the new pivoting goose neck microphone boom makes sure the dynamic microphone can always be optimally adjusted into any required position. The pivoting microphone boom can be used at left or right side or can be moved into standby (upper) position.
