Sennheiser HD 25 Plus Professional On-Ear Monitoring Headphones

The Sennheiser HD 25 Plus builds on the legendary HD 25 platform with an enhanced accessory kit — making it the preferred choice for studio engineers and professionals who need additional flexibility and extended comfort during long sessions.

Identical closed-back, on-ear design with the same 70 ohm dynamic drivers, exceptional passive noise isolation, and high SPL handling (up to 120 dB) as the standard HD 25. The rotating left ear cup allows single-ear monitoring. The split headband delivers strong clamping force and a secure fit. All key parts are field-replaceable.

• Detachable coiled cable (1–3m) fitted as standard — ideal for studio use
• Additional 1.5m straight single-sided cable included
• Additional pair of soft velour ear pads included (leatherette fitted as standard)
