---------------------------------------------------------------------- 【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ---------------------------------------------------------------------- Active Noise Cancellation (ANC) up to 50dB: 24dB average full-range depth noise cancellation blocks out external sounds even in noisy environments, allowing you to enjoy an immersive experience like being in a quiet room. High-quality sound with balanced sound and clear vocals: The combination of a 10mm dynamic driver and a polymer composite diaphragm reproduces balanced sound and clear vocals across the entire frequency range. The custom equalizer in the dedicated app allows you to adjust the frequency range from low to high in 10 bands, allowing you to create and play your preferred listening style. [Fast charging, long life]: The earphones themselves can play for approximately 10 hours, and when combined with the charging case, they can play for approximately 50 hours. The earphones themselves support fast charging, so a 10-minute charge will give you approximately 4 hours of playback, so you can rest assured even if the battery runs out suddenly. [Stable connection with Bluetooth 5.4]: Bluetooth 5.4 is used, ensuring less interruptions and reducing the lag between audio and video when playing videos or games. [IP54 level waterproof and dustproof]: The earphones themselves are IP54 level waterproof and dustproof, so you can use them with confidence even in sudden weather changes or when playing sports.
