The HMD 300 PRO supports professionals involved in broadcasting with several smart solutions. Its pressure-sensitive design offers outstanding wearing comfort even during extended sessions. The speech and sound quality are of just as professional a standard as the hearing protection facilitated by switchable ActiveGard. Together with its effective passive ambient noise attenuation and proven structure borne noise decoupling, the HMD 300 PRO offers substantially more performance than you would expect at that price.

• ActiveGard (on/off switch) for protected hearing against noise peaks > 110dB
• Highest resolution due to accurate, linear sound reproduction, optimised for speech intelligibility
• Dynamic, noise-compensated supercardiod microphone for clear communication even in noisy environment
• Microphone can be worn either on right or left hand side
• Comfortable padding design allows for extended use in long wearing sessions
• Superior ambient noise attenuation in loud environments due to closed passive earcup construction
• Due to our established modular concept the cables of the cable 26-II series are compatible
• Foldable earcup design for space saving storage
