The Perfect Broadcasters Companion
Hours of ComfortDuring the design process of the HMD 300 PRO-X4F, 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 PRO-X4F 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.
Minimising 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 PRO-X4F 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.
