Not content with annoying fellow travellers on the bus with loud phone calls on your mobile? Then check this out.
The latest gadget from Sony Ericsson is the MS500, a wireless, Bluetooth outdoor speaker that allows you to enjoy the music on your phone out in the wilds.
Available in "stylish" orange and black, or "chic" white and pink, the MS500 is apparently "the ultimate accessory for any dedicated pop rocker or dancing queen". Rules us out then.
The MS500 is designed for outdoor use, with a splash-proof shell and handy strap, which can be attached to a bag, clothing or your wrist.
It's powered by two AA batteries, which should last up to five hours, and links to your mobile phone via Bluetooth.
