Product Description
Always have your music ready when you want it with the JBL Under Armour Sport Wireless In-Ear Neckband Headphones. The neckband design is meant to be comfortable enough to be worn all day, and the tethered earbuds have a secure fit construction that are designed to stay put, even while working out. Even the neckband can be adjusted to stay in place when exercising. Flex zones on either side let you bend the neckband to secure it in place.
Your favorite music can be streamed wirelessly when paired with a Bluetooth-compatible device, such as your smartphone or tablet. When paired with your smartphone, you can use the JBL Flex to answer calls and interact with your phone's digital assistant.
Four buttons are built into the neckband with textures and shapes to make using them more intuitive. A multifunction button lets you mute the mic during calls, as well as triggering Siri or Google Now.
