The QCY M1C magnetic headphones offers you a unique sound experience. The waterproof function makes you feel free whatever you do. On the outside of the headset there is a magnet which not only allows you to have the headphones plugged in when not in use but also acts as an on / off switch. They are also compatible with most Bluetooth enabled devices. With the Noise Reduction feature, you can have high quality phone calls, even in noisy surroundings. With up to 8 hours of continuous playback time and up to 200 hours of full charge standby time, you’ll enjoy your favorite music wherever you are.
