Soundsport Free Wireless In-ear Headphone
These in-ear headphones use Bluetooth technology to connect the left and right earbuds, eliminating the need for any wires at all. Bluetooth technology is also used to pair the headphones to any compatible device in order to stream high-quality digital audio from up to 30' away. To ensure a comfortable, secure fit, the SoundSport Free headphones use Bose's proprietary StayHear+ Sport tips. These eartips come in three different sizes and are specially designed to conform to your natural ear shape, meaning they'll stay put during the most strenuous activities.
