In broadcasting and live productions, spending hours on the job is par for the course. It is precisely for this that we have developed the HMD 300 PRO: Thanks to its pressure-sensitive design, it remains extremely comfortable. Combined with a detailed sound, outstanding speech intelligibility, switchable hearing protection and effective insulation from ambient noise, it offers professionals everything they could ask for. You simply won’t find more features in this price category.

HMD 300 PRO. Everything that is important to professionals.

Inconspicuous companion

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.

Hear and be heard

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.

Minimizing disturbances

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.

Visible to everyone

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.

    Great system - mic arm a bit short

    If Sennheiser ever make an adjustment, I would gladly vote to review a Mk2 again with a longer mic boom.


    I really like these cans. I bought them for a dual purpose role, a) for monitoring the band (I'm the drummer) which could also lend me to third harmony on the mic (it works) and also b) as a ham radio operator (m0mcx), I wanted to try out a new headset. Everything is fine and I made a YouTube review video too - however I have since noticed, the microphone is always just to the left of my mouth, not directly in front. Not a big deal maybe but I need maximum drive off the dynamic capsule and I'm forever tugging the mic closer to my mouth to get a reasonable output from the mic. If the gooseneck was just 15mm longer, this would cure the problem.


    Gooseneck not long enough, needs to be longer to achieve full-frontal mouth for best sig-to-noise.


    Drummers, ham radio, broadcast, events.


    I would recommend this to a friend.
