---------------------------------------------------------------------- 【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. ---------------------------------------------------------------------- ○Semi-open type, ○Driver unit: 50mm dynamic type/neodymium magnet ○Sensitivity: 98 dB SPL (1mW), ○Frequency band: 10Hz ~30,000 Hz ○Impedance: 56 Ω (Copper-coated aluminum wire), ○Weight: 222 g (excluding cable) [Accessories] 3.5mmΦ → 6.3mmΦ gold plated conversion plug, headphone cable 1m, 3m each 1 piece Headphone cable retaining clip, carrying pouch
