wired headphones []ASHIDAVOX ST-90-07 (gray)

【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. *This is not a detachable model. 🎧 [Driver configuration] Φ40mm dynamic type 🎧 [Impedance] 40Ω 🎧 [Sound pressure sensitivity] 108dB/mW 🎧 [Playback frequency band] 5-40000Hz 🎧 [Cable specifications] Approx. 1500mm Even higher sound quality of music headphones [ST-90-05]! In addition to the engineering plastic film's diaphragm theoretical value 1 Tesla magnetic circuit, it uses Hisago Electric Materials' high-quality oxygen-free copper (OFC: Oxygen-Free Copper) cable. Furthermore, by performing optimal tuning, natural and well-defined sound quality is achieved across the entire range. Just like the ST-90-05, we are particular about domestic production, while maintaining the retro-modern design and high robustness that has been proven for "commercial use."
