For those of you who enjoy getting your entertainment through a helmet, check out this Moto GP Helmet Sound System. It’s a lot like this one. This one is built to look like a standard sized helmet, keeping your iPod (or iPhone) just behind the visor.
Your music will play through a pair of 7 watt speakers on the top and a 15 watt sub resides in the bottom. Other features include a USB port and SD card slot for playing music from another source. How much would you pay to use your device from within a helmet? This one will cost you $240.
