Brand new, unused item just arrived, ordered from Right Shop Audio online store. This is a Japan-exclusive, limited edition model that is already sold out. This product is personally owned and used by Harry from e-earphone, so if you were interested, please give it a try. I am also selling another Eddie Hsueh Re. MMCX - 4.4mm (new, unused), so please consider it as well. 【Product Description】 PW Audio x Eddie Hsueh RE. Utilizing a Sevenfold pipe design with 0.06mm copper wires, it enhances the high-frequency extension while maintaining the sound quality characteristics of copper. This achieves a wide and balanced sound across the low, mid, and high frequencies, providing a rich and delicate listening experience.
