When developing the HMD 300 PRO, we focused particularly on a high level of wearing comfort so as to take as much strain off the user as possible – even during continuous headphone use. Consequently, its mechanical design generates only minimal pressure which is distributed evenly across the soft padding of the headband and the viscoelastic earpads. In addition, a recess in the headband padding protects the pressure-sensitive fontanelle. The result: the headphones feels comfortable even when worn for many, many hours.
The acoustic elements of the HMD 300 PRO have been systematically adjusted for maximum intelligibility, even in demanding environments. This is ensured by highly sensitive transducers with precision diaphragms, which reproduce the input signals in a crystal clear manner, free from distortion. For hearing protection, Peak Level Protection can be activated which adjusts volumes above 110 dB downwards.
For the clear transmission of speech, a supercardioid, dynamic microphone is used. It is guaranteed to generate a detailed sound which can be relied on even in the loudest of environments.
In the acoustically demanding conditions experienced in broadcasting, it is important to have a reliable method for filtering out disturbances. For this purpose the HMD 300 PRO offers improved passive ambient noise attenuation by virtue of its viscoelastic earpads. Moreover, they reduce structure borne noise, something which is supported by the flexible positioning of the microphone capsule and the coiled nature of the cable directly beneath the headphone.
The HMD 300 PRO also offers you the option of customized design: you can for example have your logo applied to the side – making it clearly visible.
