Design by Studio F. A. Porsche. Sound by KEF.
Supremely comfortable lightweight in-ears combining KEF design innovation and precision engineering to give you true high resolution sound on the move.

High Resolution Sound
In line with KEF's obsessive pursuit of ever-higher sonic resolution, M100 Hi-Fi earphones deliver a noticeably fuller, crisper and more accurate response, with each vocal or instrument clearly differentiated. With ingeniously damped full-range 10mm neodymium drivers and a unique angled chamber engineered to minimise distortion, the listening experience has the intensity and detail of hearing the original live performance.

Total Comfort and Compatibility
The shell is ergonomically angled for a snug, comfortable fit while preserving M100's extraordinary clarity. Compatible with all Apple products and most other devices, and with industry standard protection against excessive sound pressure, you can enjoy true high resolution sound whenever, wherever and for as long as you wish.

Minimum Noise
An acoustic sealing ring in each ‘racetrack’ ear cup provides an excellent seal that cuts out extraneous noise while minimising sound leakage. All you hear is your chosen track in its purest form, while those around you hear virtually nothing.
