Description

Beyerdynamic DT-109 Dual Muff Headset

For many years, Beyerdynamic’s DT- 109 has been the standard headphone/microphone combination for live, remote broadcasting, studio, film, TV and language laboratory applications. The headphone transducers feature extended frequency response. The adjustable, noise- canceling microphone provides clear, audible speech transmission, and the protective ear cups attenuate up to 20 DB of ambient noise. This double-sided headset is exceptionally comfortable, with a soft headband and ear pads. The DT- 109 headset is perfect for intercom and talk back systems, as well as other applications where a dynamic microphone headset is required. The connecting cable is sold separately. The DT- 109s are rugged and durable, ensuring many years of use. Since 1924 Beyerdynamic has remained a German family-owned company committed to continuous research and innovative developments for the audio market. All over the world, Beyerdynamic is known for the use of the latest technologies and a high quality standard. All Beyerdynamic products are made in Germany.
