These neckband Bluetooth headphones feature retractable earbuds that extend to the desired length and retract when not in use. The ergonomic neckband rests comfortably around the neck while the earbuds feature yellow silicone accents that reduce sound during retraction. Bluetooth 5.0 technology provides a stable connection, and CVC noise cancelling with a built-in microphone delivers clear stereo sound for music and calls. The battery supports up to 16 hours of music playback, 18 hours of talk time, and 300 hours of standby on a 3.5-hour charge. A carrying case is included for transport.
