Combining a 10mm LF driver and a 5.5mm neodymium MF/HF driver, KEF's unique Dual Dynamic Driver (DDD) array creates an immaculately detailed and engagingly natural sound right across the frequency range, with the LF chamber connected to the light aluminium housing for tight, resonance-free bass.
KEF's discreet, flexible Secure Arm folds neatly to the shape of your ear to hold each earpiece in place, even when you're moving around. Together with an ergonomic shell and soft silicone tips that fit snugly over the ear canal to form a tight acoustic seal that eliminates external noise, they feel so natural that you soon forget you're wearing them.
For maximum comfort and enjoyment, Comply Premium earphone tips come as standard with M200. Made from a soft open-cell foam that compresses easily for insertion and gradually expands to the exact shape of your ear canal, they're an ergonomically perfect fit every time. And because they create such an effective seal, they eliminate most of the ambient noise that might otherwise detract from your listening pleasure.
