Enjoy true wireless audio with the orange SoundSport Free Headphones from Bose. 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.
In addition to music, the SoundSport Free headphones also feature a built-in mic that allows you to make hands-free calls from your smart device. Because there are no wires, playback and volume controls are conveniently located directly on the earbuds. The headphones are rated IPX4 to be both sweat- and water-resistant, so you can work out with them rain or shine. Their lithium-ion battery is rechargeable via the included charging case, and will provide up to five hours of music or talk time.
