The 300 PRO series is a pleasure to wear due to a combination of factors, including new padding material, a comfort zone for the temples of glasses and split headband padding
that removes any pressure from the sensitive area of the fontanelle.
The headphones have also been given a new fork design that ensures their contact pressure is evenly distributed over the entire ear pad, ensuring both increased comfort and excellent sealing against outside noise.
Sound reproduction modelled on the legendary HD 250 Linear
For inspiration during the design process, Sennheiser's acoustic engineers turned to the HD 250 Linear, a classic model that is still highly regarded amongst professionals today. Despite the difference in the ear cup shapes, the engineering team was able to get extremely close to the precise, linear sound reproduction of the original model, thus placing the HD 300 PRO at the peak of Sennheiser's monitoring headphone portfolio. The detailed, linear response makes the 300 PRO series ideal for music-makers, too.
Attention to detail
When superior performance is required, details matter. The 300 PRO series' detachable cables offer improved protection against handling noise, thanks to a small series of coils that acoustically decouple the cable from the headset. The series come with a rugged, bendable and twistable headband and customizable nameplates to feature a company logo on the ear cups. The new headset models also feature a noise-compensated, super-cardioid boom microphone for clear communications in loud production environments.
HD 300 PROtect headphones have been fitted with Sennheiser's ActiveGard technology, which protects the wearer's hearing from sudden sound bursts without interrupting the audio signal - an added safety feature that differs from traditional acoustic shock clipping circuitry. For European professionals, these ActiveGard equipped models are fully compliant with the EC's directive on safety at the workplace.
