Used for about 20 hours after purchasing new. All original packaging and accessories included. It's in beautiful condition. onso iect 06 Unbalanced connection 2-pin CIEM The cable is a used item and has minor scratches. The sound quality after changing the onso cable: I felt the vocals and instruments spread out. The gloss was slightly reduced, but I personally felt it became less harsh and more monitor-oriented. In short: From warm to cool. Regarding handling, this is definitely better. I used "AZLA sednaEarfit Crysta2" ear tips instead of the original ear tips, and the cable was also used for about an hour. Thank you.
