The iSound, designed by Seohyun Baek, is a set of headphones that lets you to listen to your mp3 player while still hearing the background noise around you. That’s a pretty handy thing, especially when that background noise is oncoming traffic. Old headphones=death, these=you live to get hit on another day. They use a semi-circular design that doesn’t cover your whole ear, that way some background noise is still heard. The unit is wireless with a bluetooth module that connects to the headphone jack in your mp3 player. Excellent concept that will surely find a market.

I have a first generation iPhone and like it a lot. One of the worst things about it though is that if you watch many videos on it the battery drains very quickly, iPod owners have this same problem. This fact has led to the proliferation of back up batteries for the iPhone and the iPod. Some batteries are only for the iPhone like the iPhoneck we talked about before.

If you want something a bit more universal that will work for your iPhone, the iPhone 3G coming this week and your 30-pin connector iPod, i.Sound has the battery for you. Called simply the i.Sound Back Up Battery the little device is a 2-in-1 charger that can charge your phone and the internal battery at the same time.
