------------------------------------------------------------------------------------------------------------------ 【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. ------------------------------------------------------------------------------------------------------------------ Technical compliance mark certified product (frequency band: 2.4GHz band) Achieves up to 70 hours of wireless listening without charging for approximately one month Lightweight body with excellent portability, swivel & folding mechanism Around-ear type with simple design and comfortable fit Isolation design separates acoustic space and electrical space to achieve clear sound Φ40mm driver that achieves high resolution playback despite being compact Included items: Cable blue
