ivipQ-512 4.4mm mmcx High Purity Silver Palladium Used for about 3 months after purchasing new. I couldn't find any noticeable scratches, but it's a used item, so please consider purchasing if you understand this. *Regarding MMCX, noise may occur due to poor contact depending on the earphones. Please note that we cannot accept returns in such cases. In my usage environment (Shure SE846), it worked without any problems. Also, I haven't done any recabling except for removing it to list it for sale after attaching it to the earphone body, so I think there is little wear and tear. To prevent trouble, please understand that we may cancel transactions with those who have many negative ratings or no transaction history.
