---------------------------------------------------------------------- 【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. ---------------------------------------------------------------------- ●4-pole model with 3-pole conversion adapter that can be used with a wide range of devices from smartphones to PCs ■Compatible models: Windows PCs, tablets, smartphones, PS4, and Macs equipped with a 3.5mm 3-pole or 4-pole mini plug ■Connection method: 3.5mm 4-pole mini plug (CTIA standard compliant) [Headphone section] Driver unit: φ40mm Frequency response: 20Hz-20kHz [Headphones] Sensitivity: 111±3dB Impedance: 32Ω Maximum Input: 25mW [Microphone] ■Directivity: Omnidirectional ■Frequency Range: 50Hz-10kHz Microphone: Sensitivity: -42dB ±3dB Impedance: 2.2kΩ ■External dimensions (W x H x D): W152 x H167 x D58 mm ■Weight: 105 g ■ Package dimensions (width x height x depth): W200 x H250 x D60 mm ■ Package weight: 190 g ■ Cable length: 2.0m ■ Operating environment: Temperature 5℃~40℃, Humidity 10%~90% ■ Product configuration: Main unit, 3-pole mini plug conversion adapter
