Product Overview
The Sennheiser HMD 300 Backstage (SKU 700315) is a closed-back circumaural broadcast headset with switchable ActiveGard hearing protection and a supercardioid dynamic boom microphone, designed for backstage broadcast communication in high-SPL live production and broadcast environments.

Product Description
The HMD 300 backstage broadcast headset is built for production professionals who require reliable voice communication and hearing protection during live events and broadcast productions in high-noise environments.

The closed circumaural design provides up to 32 dB of passive noise attenuation. Headphone frequency response of 60 Hz–25 kHz covers program audio and IFB monitoring requirements. Boom wearable on either left or right side. Compatible with Sennheiser Cable 26-II series (sold separately).
