Combining a high-quality audio solution with a lightweight and comfortable design, the Apple Beats Flex Wireless In-Ear Headphones streams audio through a dual-chamber acoustic design, delivering pronounced stereo sound with deep, rich bass. Laser-cut micro-venting and an optimized driver angle also work to keep that audio clear, while providing ear relief during extended use.Unlike a typical rigid neckband, Beats' Flex-Form cable can conform to most any neck shape. When you're not listening to music, the magnetic earbuds click together to keep them tangle-free and immediately within reach when needed. The Beats Flex pairs with most any Bluetooth-compatible device and utilizes Class 1 Bluetooth technology for an extended wireless range past the typical 33' of Class 2. On a full charge, they playback music, podcasts, and more for up to 12 hours.
