Key Info
Sennheiser HD300 PRO are Professional Monitoring Headphones Based on the iconic HD 250 Linear

Based on the iconic HD 250 Linear

During the design and development of the HD 300 PRO 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 is the flagship model in Sennheiser's monitoring headphone range.

Comfortable during long monitoring sessions

The HD 300 PRO headphones feature padded earcups, a split headband and a comfort zone for the temple. Listening fatigue is minimised 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 ear pad, helping to further increase comfort and background noise attenuation.
