Well enough of Bluetooth headphones and earbuds claiming to be outstanding when it comes to filtering and eliminating all the background and surrounding news but one thing for sure they aren’t suitable for the ever increasing bicyclists and joggers since they need to hear the surrounding noises particularly the blaring sound made by a vehicle horn.

Well with Semicircle headphones coming into the picture you needn’t worry as it perfectly fits in your ear without obstructing background noise at all. The wireless unit comes along with a Bluetooth module that connects to a standard headphone jack.

The simple yet innovative concept is an invention from Seohyun Baek but it is expected that it won’t hit production anytime soon indeed! Truly a safe concept particularly for all the bike riders.
