Monitor your audio with accuracy and clarity. The Senheiser HD 300 PROtect headphones are perfect for live performances and studio recording sessions. Hear every detail of your sound from the deep beats to delicate high nuances thanks to the large dynamic drivers which produce high-resolution and distortion-free audio. ActiveGard technology protects your hearing from unexpected peaks in volume without interrupting the signal.
Offering class-leading isolation, the HD 300 PROtect headphones eliminate up to 32dB of ambient background noise, ensuring loud environments don’t impact your ability to monitor. Suitable for critical listening applications and long monitoring sessions, the Sennheiser HD 300 PROtect have a unique design with comfortable padded and reduced contact pressure. Based on the iconic HD 250 Linear headphones, the HD 300 PROtect are Sennheiser’s flagship monitoring headphones.
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 modeled so closely on the legendary HD 250 Linear.
During the design and development of the HD 300 PROtect headphones, Sennheiser’s acoustic engineers turned to the HD 250 Linear headphones. Why the HD 250 Linear? The reason they chose these headphones is that they’re still highly regarded by audiophiles and professional sound engineers today. Despite the difference in the ear cup shape, Sennheiser’s engineering team were able to recreate an almost identical linear frequency response. This results in precise audio reproduction that is incredibly detailed. The HD 300 PRO series is the flagship range in Sennheiser’s monitoring headphone lineup.
Comfortable during long monitoring sessions, the HD 300 PROtect headphones feature padded earcups, a split headband, and a comfort zone for the temple. Listening fatigue is minimized and pressure from the sensitive area of the fontanelle is reduced to a minimum. A unique fork design ensures that pressure is evenly distributed across all of the earpad, helping to further increase comfort and background noise attenuation.
Consistent audio reproduction. Innovative technology protects you from sudden peaks in the audio volume without interrupting the overall audio signal. Sennheiser’s ActiveGard™ technology is a unique feature that is completely different from traditional acoustic clipping circuitry. The HD 300 PROtect headphones are also completely compliant with the EC’s directive on safety within the workplace.
