40mm drivers tuned by KEF engineers, together with a large 20mm neodymium magnet and lightweight CCAW voice
coil deliver crisp high tones, rich midrange and tight bass.
Soft, sweat resistant, padded leatherette band and ear cups make listening to music comfortable even over long journeys.
The aluminium band clamps gently and securely around the ears to create a solid seal for improved acoustic isolation.
Active Noise Cancellation can be switched on and off as needed, so that in situations where you need to hear your surroundings you can.
Fully charged, the AAA battery lasts for up to 50 hours of playtime with active cancellation turned on.
