Some companies excel at making lots of products, and others do really well with just a few. English audio engineers KEF sit in that last category, and for its second pair you wear on your head, it’s not just about sound.

For the fourth portable sound product in its line-up — and the second headphone the company makes altogether — KEF is making sure it doesn’t just have the audio chops down.

It more than likely has that, because this isn’t just a brand that knows speakers, as we’ve seen some pretty impressive headphones from KEF in recent years since it started making them.

So KEF is already on top of the sound, and will be bringing 40mm neodymium drivers and a copper coated aluminium wire voice coil to the new headphones.

But again, it’s not just about sound, because while the KEF M500 headphones pretty much went for a basic silver and black colour scheme, these new ones — the KEF M400 — are about colours.

You’ll find four of them to choose from, all made from machined aluminium, offering “Racing Blue”, “Sunset Orange”, “Champagne White”, and black (which isn’t special enough to get a nifty name).
