KEF joins the headphone market with M500 and M200

23 Apr 2013

KEF M500

KEF is the latest hi-fi company to join the headphone market with the launch of the M Series headphones, the M500 over-ear and the M200 in-ear models.

The company claims to have brought its extensive experience in speaker design to the portable market, blending its audio expertise with high-quality industrial design and manufacturing to deliver the new M Series headphones.

The over-ear M500s, selling for £250, use a full-range 4cm driver with a neodymium magnet and light, copper-clad aluminium voice coil tuned by KEF's engineers to deliver "a powerfully musical sound with tight, clean bass".

A precision-engineered aluminium frame, with breathable and sweat-resistant memory foam earpads and headband, features a 'smart hinge'.

Unlike other headphones that require two hinges to fold and rotate the earpads, the M500's smart hinge rotates on two axes, so they can easily be folded up for carrying around in the hard case provided.

Also new from KEF are the £150 M200 in-ear headphones, which use Dual Dynamic Driver technology – a two-way system with a 1cm driver for the bass and a 5.5mm neodymium-magnet driver for midrange and high frequencies – housed in an aluminium enclosure.

A rubber 'secure arm' hooks over the ear to keep the M200s securely in place.

Both models include an inline mic and volume controls for making and receiving phone calls from your smartphone, and adjusting music volume.

The M Series are also compatible with the Cenelec standard for protection against hearing damage caused by excessive volume levels.

Most 'made for iPhone' headphones will work with other phones with the use of a pin 3 & 4 switch adapter.

I've use a few pairs successfully with my Nokia using this :

I'd say the M500s were on-ear rather than over-ear aren't they? 

They sound bloody great! Better than a few new ones I've tried recently. 

Currently testing a pair of M200's....

AFAIK we got a review pair of one of the models when we were shown them end of last week. We'll try to get someone to check them with an Android handset, and report back.

EDIT: The response from KEF is that only the miiddle button will work consistently with Android devices, but various other functions will work depending on the phone – and Android version – in question. The problem being that, as Andoid is open source, different manufacturers assign different functionality, so for example one phone from a given manufacturer could have different functions to another.

Subject to auditioning or a trustworthy sensible review I have already started saving for both, unless it is iPhone only and then I 'll not bother!


From the KEF webpage

"Compatible with most smartphones, computers and other mobile devices. Featuring an integrated in-line microphone and remote control on a tangle-free flat cable for iPhone and other Apple products,"

so is the remote Android compatible or not?

They look lovely but if the remote is iPhone only I'll be rather disappointed.
