About the King Lucky i31PRO

Comfort and Safety: The KING LUCKY i31 wireless earphones are crafted with shape-memory alloy wires and high-quality silicone material. Featuring an open-ear design that can be adjusted freely, they are characterized by their "ear-friendly and secure fit." Compared to in-ear or bone conduction types, the pressure on the ear and ear canal is reduced, providing a comfortable fit and less impact on hearing. Ideal for listening to music while exercising or doing housework, they allow you to hear external sounds clearly and respond to your surroundings safely.

High-Speed and Stable Connection: Utilizing Bluetooth 5.3, the earphones ensure high-speed transmission and stable connections within a 10m range, compatible with various Bluetooth-enabled devices like iPhone, Android, Windows, and iOS, with minimal delay or sound dropouts. Pairing with devices is only needed once; after the initial setup, simply opening the charging case will automatically connect the earphones.

High-Quality Music Playback and Voice Calls: Equipped with a large 16.2mm dynamic driver, it delivers deep bass and clear, lossless surround sound. The earphones also feature a proprietary dual-microphone noise reduction system that suppresses background noise and captures voices accurately, ensuring clear and realistic communication. Additionally, technology to control directivity helps minimize sound leakage. (Note: Due to the open-ear design, complete prevention of sound leakage isn't possible, so please be mindful of the volume in public places like trains or cafes.)

Easy Operation and Sweat/Water Resistance: Smart touch controls allow for easy music playback, volume adjustment, and call management with a light touch. They are also IPX5-rated for water resistance, making them durable against rain and sweat during exercise.

48-Hour Long Playback: Up to 10 hours of music playback on the earphones alone, and up to 48 hours with the charging case. Includes support for Japanese voice guidance as well as Siri and Google Assistant.

Reliable Warranty: Products purchased from the KING LUCKY Amazon official store come with a 3-month exchange warranty and a 24-month repair warranty. If you encounter any defects or issues during normal use, please contact us via the phone number provided for support.
