ALO audio Pure Silver Litz 4.4mm MMCX cable. This is a one-owner item and has been working without issue with my WM1AM2 and ZX707. Compared to when I purchased it, the cable has slightly yellowed, and there is some greening on the plug, but it works without any sound degradation. It's very flexible and has very little touch noise, making it recommended for everyday use. *Please note that it is not compatible with Sennheiser MMCX.* It was stored in a dehumidified storage box when not in use. The original box and pouch are included. Due to the discoloration and greening of the plug, the condition of the product is listed as "slightly scratched or dirty." Thank you for your understanding.
