KEF M100In-ear headphones with Apple® remote and microphone.

Grab-and-go headphones with a sound pedigree

KEF M-100

The KEF M100 in-ear headphones are specially angled to fit securely and deliver clear sound.

Although I'm currently testing several different kinds of headphones, lately I reach for the KEF M100 in-ears as soon as I wake up. Whether I'm making coffee, letting the dog out, or packing lunch for the day, it's just so easy to pop in these earbuds and go through my morning routine. With the M100s, KEF certainly brought their 50-plus years of sound expertise. And they clearly understand the importance of a comfortable fit.

Designed for top performance

The M100's precisely angled drivers are designed to minimize distortion and deliver pure, dynamic sound. I found these headphones particularly strong in the mid-range, where most music lives, but what struck me more was how they handled speech. I listen to a lot of podcasts, and they aren't always top-quality recordings. The M100's combination of noise isolation and the unique driver design made the dialogue come through clear. Without cranking the volume up to dangerous levels, I was able to follow the back-and-forth conversations.
