KING LUCKY / i31pro Max Gold Completely Wireless Earphones

KING LUCKY / i31pro Max is a completely wireless earphone that allows you to enjoy music while naturally capturing surrounding sounds with an open-ear (air conduction type) design.

■Super lightweight 7.4g
- Ultra-lightweight 7.4g for an over-the-ear type, it feels as light as a feather and provides so much comfort that you forget you're wearing it.

■Sound leakage control
- By adopting a large 18.7 x 11.3 mm oval driver and a uniquely designed J-shaped speaker, the directivity of sound waves is controlled more precisely and accurately, providing clear and powerful sound while minimizing sound leakage.

■Multi-point
- Equipped with a multi-point function that allows you to connect to two devices at the same time, so you can answer calls received from other devices even while playing music or talking on a call.

■Call noise reduction
・Each earphone is equipped with two Goertek MEMS silicon microphones, and the ENC call noise reduction function combined with an AI algorithm that learns noise data performs high-definition noise reduction on a variety of sounds, allowing you to convey clear and realistic voice to the other party.
