Tokyoflash - cool bluetooth handsfree clock stereo handsfree thing
Anyhow this thing pairs via bluetooth to a phone or mp3 player or desktop/laptop and you can then plug a standard pair of headphones into it and listen to music or make hands-free phone or skype calls. It also displays the time... once you work out what all the leds stand for!
So weird, but actually quite functional - allows you to use any comfortable headphones wirelessly with your 'phone or laptop. And the clock thing can make for an interesting "try to work out the time" party game.
If you spend a few extra dollars (ie if you spend more than 10,000 yen ie about US$106) then shipping is free.
