HMD 300 X3K1

Article No. 700317

The ergonomic HMD/E 300 professional broadcast headsets excel in the energy and volume of backstage broadcasting environments. Featuring a comfortable, closed circumaural design, switchable ActiveGard© limiting technology, reduced structure-born noise, and a dynamic boom microphone that can be worn on the right or left side, they provide ideal performance at an exceptional value.

The HMD 300 XK31 broadcast headset offers innovative communication solutions at great value. The closed-back, circumaural headphone design delivers a frequency response of 60 Hz to 25 kHz. At the same time, ActiveGard© limiting technology, compression technology, and passive ambient noise attenuation exceed your audio quality expectations, while a super-cardioid, dynamic microphone ensures you will be heard loudly and clearly. The HMD 300 X3K1 includes a copper XLR 3 to 6.3 mm cable that reduces structure-born noise.
