Sennheiser HMD301-PRO Single-Ear Pro Broadcast Monitoring Headset

The HMD 301 is a broadcast monitoring headset from Sennheiser that delivers superb sound with a comfortable fit for those long production days. It’s a single-ear headset that features a soft, notched headband, which provides lower wearing pressure. A recently-developed ear pad includes a comfort zone to reduce pressure when wearing glasses, while still delivering an excellent seal for high passive noise attenuation. It has acoustic elements that have been engineered to deliver maximum audio detail and intelligibility, even in the most demanding production environments. Its ultra-linear drivers–recently developed by Sennheiser–offer clear, natural, distortion-free sound, while an on board supercardioid, dynamic boom mic captures incredibly-detailed speech. Sennheiser’s proprietary ActiveGard™ peak level protection can also be activated to provide hearing protection for from excessive sound levels and peaks above 110dB.
