Thank you for viewing. Manufacturer: M&M DESIGN Model: SN-MD5050 Length: 3.0m Custom Specification: FIIO arrangement on one side Usage Period: 3 years Used for 3 years connecting a FIIO M9 and HELIX DSP (in the same car). It was functioning without any problems until removal. There may be traces of cable ties and other signs of use. The current retail price is ¥66,000 including tax. I cannot answer questions regarding compatibility with devices other than the FIIO M9. No claims and no returns accepted.
