Essential Info

The AfterShokz sports headphones are the perfect musical companion for anyone who participates in outdoor activities like jogging, biking, or hiking and enable you to still hear the ambient noises of what is around you. If you are running or biking on city surface streets, it is important to hear the noise of the traffic around you so you can keep yourself safe. With the AfterShokz headphones, there is nothing in, on or covering your ears so you are able to hear what is around you while still enjoying your favorite music. Featuring military Special Ops bone conduction technology, the headphones have a wrap around band and sit comfortably in front of the ear, delivering sound through the listener's cheekbones to the inner ear. These headphones are lightweight, sweat and water resistant and provide listeners with a fabulous stereophonic audio experience while also allowing them to hear ambient noises such as oncoming traffic, car horns, ambulances or other warning noises, potentially preventing accidents caused by headphones and earbuds that block out these sounds. Complete with an in-line control and standard 3.5mm connector, these headphones will fit any iPhone, iPod, iPad, MP3 player, and most other smartphones and have a lifetime warranty. An in-line microphone allows you to accept phone calls and communicate with the person on the line.

The AfterShokz headphones also offer the Sportz 2 model. The Sportz 2 does not have an in-line microphone.
