Sony Ericsson may soon make the play button a thing of the past with its new motion-controlled earbuds. The handset-maker on Monday unveiled its MH907 headphones that allow you to play your music and answer phone calls just by inserting the buds into your ear or taking them out.

How it works

To listen to music you simply put both earbuds in, and your music starts automatically. To pause, take out one earbud; removing both stops the music entirely. To answer the phone, do the same thing. If you're listening to music when a call comes in, you have to remove both earphones to stop the music, and then put one back in to answer a call.

Sony Ericsson says the MH907 headphones are activated by body contact, so you can't accidentally answer a phone or start your music when the headphones are in your pocket or purse.

Compatible phones

If you were hoping to pick up a pair of these for use with your iPhone or other smartphone, you can forget it. The MH907 is only compatible with Sony Ericsson's own Fast Port-equipped phones -- Fast Port is SE's proprietary connector on the bottom of its phones.

Pricing, colours and other features

Sony Ericsson didn't reveal any pricing information, but rumor has it these earbuds will set you back anywhere between US$55 and $60. Available colours include yellow and white or titanium chrome. Other features include a built-in microphone, FM antenna, sound-blocking (the MH907's are not noise-cancelling headphones) and stereo sound.

Sony Ericsson says the MH907 headphones will be available worldwide later this week.
