Here are the details of the Beats Flex - All-Day Wireless Earphones - One Size Beats Black. FLEX ALL DAY The Flex-Form cable provides all-day comfort with durable Nitinol construction, while four ear tip options offer a personalised fit. Magnetic earbuds make listening that much easier by automatically playing music when they’re in your ears and pausing when they’re attached around your neck (1). THE MUSIC STOPS WHEN YOU DO Less charging. More flexing. Beats Flex boasts up to 12 hours of listening time for all-day use. If you need a little extra power, 10 minutes of Fast Fuel charging gives 1.5 hours of playback when the battery is low (2).
