Broadcast Headset
A Perfect CompanionThe Sennheiser HMD 300 is perfect for professional broadcasters with many clever solutions. The pressure-sensitive design gives you fantastic comfort even when wearing for very long sessions. The speech and sound quality live up to a professional standard as the hearing protection is operated by a switchable ActiveGard. Combined with its effective passive ambient noise attenuation and proven structure borne noise decoupling, the HMD 300 delivers a lot more performance than you would expect from this price range.

Amazing Features
• Large diaphragm cartridge provides wider dynamic range for clear highs and strong lows
• Cardioid polar pattern picks up audio from the source while rejecting unwanted noise
• Updated industrial design with black metallic finish and grille for unobtrusive visual presence
• High-pass filter for additional control of unwanted low-end signal
• -15dB switchable attenuator for additional SPL versatility
A Perfect Broadcasters Companion
Hours of ComfortDuring the design process of the HMD 300, Sennheiser focused on making this headset a high level of wearing comfort, so that users can use these headphones continuously without any strain or set back.
As a result, the mechanical design of the HMD 300 creates very little pressure which is spread evenly across the soft padding of the headband and the viscoelastic earpads.
Also providing further comfort is the recess in the headband padding. This protects the pressure-sensitive fontanelle. Thanks to all this the headphones feel comfortable even when worn for long time periods.
Hear & Be Heard
Detailed SoundThe acoustic factors of the HMD 300 have been carefully adjusted for maximum functionality, even more difficult environments.
This has been achieved by highly sensitive transducers with precision diaphragms, which recreate the input signals will full clarity and no distortion. For protective hearing, Peak Level Protection can be selected which adjusts volumes above 110 dB downwards.
When capturing speech clearly, the HMD 300 features a supercardioid, dynamic microphone. This guaranteed to capture a clear and detailed sound, which can be relied on even louder settings where you would usually get background noise.
Minimizing Disturbances
Consistent & ReliableIn the acoustically challenging conditions often found in broadcasting, it is vital to have a reliable method for reducing background disturbances.
The HMD 300 delivers improved passive ambient noise attenuation by the use of its viscoelastic earpads.
They also reduce structure borne noise, something which is helped by the flexible positioning of the microphone capsule and the coiled cable directly under the headphone.
