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

At KEF we care about clarity and we care about detail. With M500 you experience the uncompromised sound of music as if hearing it live: vivid, spacious and exquisitely balanced.

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.

Design Story

Precision Design

Music you can feel - so realistic you can almost touch it. KEF’s ultra-light driver technology and voice coil system are designed to preserve all the glories of the original performance in full-range high definition: crisp, intricately detailed highs, seamlessly fluid midrange and tight, clean bass. Opera or Hip-Hop, on the move or just chilling, you experience every note.

A masterpiece of KEF's innovative acoustic engineering in miniature, M100 Hi-Fi earphones share the same design integrity and build quality as the rest of the M Series range. The aluminium 'race-track' casing is precision machined with diamond-cut chamfered edges, and the internal components are exhaustively tested for consistently accurate response. Nothing is overlooked, right down to the environmentally friendly new benzene-free production process - another KEF 'first'. There are four cool colour finishes to choose from: Racing Blue, Sunset Orange, Titanium Grey and Champagne Gold.

Full Review



"These earphones are precisely machined with attention to detail and have a high-grade appearance. They not only deliver outstanding sound but also have a sophisticated look." - 2015



"We were impressed by KEF’s first headphones, the M500 on-ear cans, and the M100 in-ears are really no different. They offer excellent build quality, a lightweight comfortable design combined with nicely balanced and crisp sound performance. They're also not as pricey as we had expected, making them a solid choice for a pair of in-ear headphones." - 2015
