The ergonomic HMD 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 S single-sided 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.
