The Sony Ericsson MH907s are the first motion-activated earphones we’ve clamped to our ears, but does that mean these buds are exercise fascists that’ll only serve up beats if you’re running flat out? We find out how many calories you’ll have to expend in this Sony Ericsson MH907 review.
Thankfully, the truth is a lot less out-there than you might at first assume. The Sony Ericsson MH907 earphones don’t so much sense motion as the presence of your ear canal. Each sound-isolating rubber tip acts as a capacitive switch that can tell when it’s being touched by your skin.
So, when used with a compatible Sony Ericsson phone, the Sony Ericsson MH907s cut out when one of the buds is removed from your ear. It’s not just muting the sound either but actually pausing playback within your phone’s media player. Clever stuff.
Playing the smarty pants card in tech gadgets is often a recipe for trouble, but – for the most part – the ear-sensing technology in the Sony Ericsson MH907 earphones works perfectly. Occasionally we found that the sound didn’t cut out upon removing a bud, but this was a rarity and the sensor tech never actually stops you from listening to anything – you can override it with a tap on the phone’s normal play button. So, it’s not the end of days for one-eared listening.

Even more of a surprise than the fact the ‘motion sensor’ gimmick actually works is that the sound quality is excellent. Full, taut bass and treble that relays an amount of detail unusual at this price point – without being harsh or sibilant – give the Sony Ericsson MH907s just about the sweetest aural experience you can have for under £40.
The Sony Ericsson MH907s are less harsh than the Denon AH-C452s, have much more controlled bass then the Skullcandy Full Metal Jackets and a shade more detail than the ever-popular Sennheiser CX300s. The high-end sounds ever so slightly compressed, but the sound-per-pound ratio is stacked heavily in your pocket’s favour here.
In fact, The Sony Ericsson MH907 earphones sound so good, we only wish we could use them with MP3 players and other devices rather than just Sony Ericsson phones. You can’t though because they use a pesky proprietary connector. Team them up with a Walkman phone though and you’ve got a match made in heaven.
