[BLUETOOTH 4.1 + APTX] - SoundPEATS Q12 Bluetooth headphones support two devices connected simultaneously and allow automatically reconnecting if paired successfully before. They own high fidelity stereo sound with aptX codec. 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 8 hours talk / 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 0.53 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.
