------------------------------------------------------------------------------------------------------------------ 【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. ------------------------------------------------------------------------------------------------------------------ Format: Sealed over-ear, Playback frequency response: 15Hz~25kHz Impedance (1kHz): 49Ω, maximum input: 1600mW, output sound pressure level (1kHz): 99dB SPL/mW Driver: Φ40mm, dynamic, CCAW voice coil, cable: 3.0m straight, terminal: 3.5mm stereo mini plug, 6.3mm stereo standard plug Dimensions (excluding cable and plug): 170 x 195 x 98mm, Weight (including cable and plug): 360g Accessories: 6.3mm stereo standard plug conversion adapter, carrying bag
