More features for your money
In broadcasting and live productions, it is usual to spend hours at work. This is precisely why we developed the HMD 300 PRO: thanks to its pressure-sensitive design, it remains extremely comfortable. With detailed sound, exceptional voice intelligibility, switchable hearing protection and effective isolation from ambient noise, it offers professionals everything they could ask for. More features in this price category do not exist.
HMD 300 PRO. Everything that matters to professionals.
Discreet companion
When developing the HMD 300 PRO, we placed particular emphasis on a high level of wearing comfort in order to relieve the user as much as possible. even during continuous use of the headset. Therefore, its mechanical design generates only minimal pressure which is distributed evenly throughout the soft padding of the headband and viscoelastic ear cushions. In addition, a hollow in the headband padding protects the fontanelle, which is particularly sensitive to pressure. Result: the headset is comfortable even when worn for hours and hours.
To understand and to be understood
The acoustic elements of the HMD 300 PRO have been systematically adjusted for maximum intelligibility, even in demanding environments. This intelligibility is achieved through highly sensitive precision diaphragm transducers that reproduce input signals with crystal clarity, without distortion. For hearing protection, peak level protection can be activated to lower volumes above 110 dB.
For clear speech transmission, a supercardioid dynamic microphone is used. It ensures detailed sound that can be relied on even in the noisiest environments.
Minimization of disturbances
In the demanding acoustic conditions encountered in broadcasting, it is important to have a reliable method of filtering out disturbances. To do this, the HMD 300 PRO offers better passive attenuation of ambient noise thanks to its viscoelastic cushions. In addition, they reduce structure-borne noise, which is favored by the flexible positioning of the microphone capsule and the spiral cable directly under the headset.
Visible to all
The HMD 300 PRO also offers you the possibility to personalize the design: for example, you can have your logo applied to the side, making it clearly visible.
