Product Research


Overview: The Sennheiser HD 25 supra aural (on-the-ear) headphones are extraordinarily lightweight and comfortable. This allows you to wear them for long periods of time without fatigue. The headphones are ideal for DJs, studio monitoring, and sound booths. The HD 25s have a non-detachable 58" straight cable with a right-angled 3.5mm plug. A 3.5mm-to-6.3mm adapter for use with audio equipment that has a standard 1/4" headphone jack.

Closed Design: The HD 25 headphones feature a closed design to isolate external noise. This allows you to have an enjoyable listening experience in the quiet of your living room, on a commuter train, or in the workplace. The adjustable headband and soft ear pads provide hours of comfort for extended listening.

Aluminum Voice Coils: The headphones are equipped with lightweight aluminum voice coils, which makes them very lightweight, but also makes them capable of handling very high sound pressure levels. The high sensitivity enable them to perform well in loud environments.

Rotating Ear Cup: One of the ear cups can be rotated nearly 90° in either direction, enabling you to listen with one ear, if you desire.

  • Power Handling: 200mW
  • Max Sound Pressure Level (active): 120dB
