Achieve HIFI-level sound quality with this silver and copper mixed OTG cable. It's very cool with its solid construction and flexible cable. - Type: Type-C to Type-C - Material: Silver + Copper Mixed Exceeds the ddHiFi TCO9S OTG cable, offering a wider range and a sense of realism. Also, the resolution is quite good, and I felt the sound was thick, like a high-end OTG cable, with clear sound quality. It's only been used for auditioning and is in like-new condition, so please rest assured. I'm also trying out various other things, so I'm selling this one.
