---------------------------------------------------------------------- 【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. ---------------------------------------------------------------------- The three EQ equalizer modes, tuned for Japan by professional tuners, allow for even more subtle expression of sound quality: 1. Balanced mode (balanced high and low frequency experience), 2. Deep bass mode (amplifies the bass beat of melodies for a vibrant musical experience), and 3. Vocal mode (reducing the bass by 3 dB to focus on the singer's vocal range). Thanks to the new Bluetooth chip, the headphones' power consumption has been improved, and with the same 1000mAh capacity, the continuous playback time has increased from 50 hours to 90 hours (at 60% volume).
