When you are cycling around town, listening to your iPod with noise-canceling earbuds isn't the best idea. You get distracted and you won't hear what's happening around you. Thankfully, designer Seohyun Baek has come up with a solution to this problem, while keeping the music flowing to your ears.

Most headphones are designed to keep sounds from the outside away, which can be problematic. The Semicircle headphones are designed to fit in your ear without blocking sounds from the outside. The earphones are wireless and come with a Bluetooth module that can connect to a standard headphone jack. For now, this is only a concept.

This is utterly retarded. Pretty much any non-noise canceling earphone will allow plenty of ambient noise to enter as long as you aren't cranking the volume up.
This is in no way retarded. Non-noise canceling earphones allow a decent amount of ambient noise to enter, but still block enough to make riding a bike unsafe. Normal earphones still physically block a good deal of the ear canal, which is plenty to keep you from hearing the car coming up behind you. This is perhaps stupid for normal applications, but makes a lot of sense for cycling. (Now why you need to listen to music on a bike anyway is another good question...)
