------------------------------------------------------------------------------------------------------------------ 【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. ------------------------------------------------------------------------------------------------------------------ ■Renewal package model of the ever-popular headphone "HD25-1 II" ■Sound quality performance is equivalent to HD25-1 II ■Simple configuration with only 6.3mm stereo standard conversion plug included ■Model: Dynamic/closed type ■Frequency characteristics: 16-22,000Hz ■Impedance: 70Ω ■Sensitivity: 120dB ■Cable shape: Approximately 1.5m steel cable (one side out on the right side) ■Plug shape: Stereo mini plug (L type) ■Body weight: Approximately 166g (including cable and plug) ■Accessories: Stereo standard conversion plug This is a new packaging version of the popular "HD25-1 II".
