By coincidence I stumbled across an interesting gadget, it’s something called JawBone.

Initially it seem like an ordinary blue-tooth headset, well it is but with a twist – it uses an elaborate background noise cancellation technology and it seem to do so very well indeed (watch video below). So if you use your blue-tooth headset in noisy environments then this may be something for you.
