Wireless and Wired Connections for Your Convenience

The AudioMX HG-21B headphones support both wireless and wired connections. The headphones can be used wirelessly when working together with the transmitter, boasting up to a 30 m transmission range. What’s more, the innovative digital 2.4 GHz technology ensures that signal transmission remains clear and accurate, giving you the finest quality sound every single time. You can also connect the headphones to your 3.5 mm / 6.3 mm audio device directly with the supplied audio cable.

Headphones Charger, Transmitter and Stand All-in-One

The improved contraction spring charging pins and groove fixing design make charging the headphones a breeze. To charge, place the headphones on the top of the transmitter. Make sure the charging pins of the transmitter and headphones are matched. The headphones automatically stop charging after fully charged with the indicator turning off.

40 mm OFC Domelike Driver Units

The OFC (Oxygen-free copper) voice coil provides exceptional and stabilized audio performance in all ranges of frequencies. You’ll be able to hear the subtle nuances of dialogues and the slight details of your favorite music like never before.

Ergonomic Design and Skin-Friendly Material

The headphones surface comes with a unique matte finish, which keeps it clean and fingerprint-free at all times. The TPE/ABS composite materials make the headphones lightweight and elastic. The retractable headband is designed to fit users with different head sizes. In addition, the ultra-soft ear cushions cover your ears snugly and comfortably for extended periods of use.
Closed-Back Design

The closed-back design effectively isolates you from ambient noise while reducing the possibility of sound leakage. Fully enjoy your lives, TV and movies without disturbing your family and friends.
