The Sennheiser 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.
