BLUETOOTH 4.1: Tiergrade Bluetooth headphones support two devices connected simultaneously and allow automatically reconnecting if paired successfully before. The headphones are widely compatible with most cell phones, such as iPhone and Android phones, and also plenty of other Bluetooth devices.
LONG-LASTING & LIGHTWEIGHT: Upgraded built-in lithium batteries support up to 7 hours talk or music time (depends on volume and audio content) for prolonging enjoyment. Only charge for 1-2 hours can get full energy back. The surprisingly ultra light design at only 0.55 ounces net weight barely makes you feel anything during workout.
BUILT-IN MAGNETS: Both earpieces are with built-in magnets which can attach to each other like a necklace around your neck when not in use. This elegant design helps earphones storage and keeps you away from getting entangled with the wire. You''ll find it most convenient to carry the earphones around for any outdoor activities, such as hiking, cycling, sports, exercise, and more.
SECURE & COMFORTABLE FIT: Tiergrade Bluetooth headphones are ergonomically designed to fit your ear canal better and reduce noise. In addition, with 4 pairs of ultra soft ear tips (XS/S/M/L) and 4 pairs of ear fins included, the earphones ensure comfortable and secure wearing and using experience.
Tips: When charging with a charging adapter, please make sure the current should not be greater than 1A. Tiergrade provides 12 months hassle-free warranty to ensure the enjoyment of your purchase.
