Sennheiser Anounces New 300 PRO Series Headphones and Headsets

With the 300 PRO series, Sennheiser launches new headphones and headsets designed with this demanding context in mind, fine-tuned with users to deliver when and where it matters. Alongside outstanding comfort, the 300 PRO series offers precise sound reproduction.

Available from August 2018, the new series includes the HD 300 PRO and HD 300 PROtect monitoring headphones as well as the HMD 300 PRO and single-sided HMD 301 PRO communications headsets.

“Comfort was a paramount design criterion for the circumaural 300 PRO series,” said Nicole Fresen, product manager at Sennheiser. “Thanks to multiple field tests and a thorough fine-tuning process, these headsets have met with very high user approval. We found operators and engineers to be incredibly pleased to listen to a pair of headphones that was modelled so closely on the legendary HD 250 Linear.”

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.

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.

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.

All HMD 300 PRO headsets and the 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.
