ELECOM AV-35AD02BK Brand new, unused, and unopened. Due to long-term storage, there is some peeling on the edge of the package, as shown in the second photo. Also, if you would like a guaranteed working product, I can take it out, test it with my own headset, confirm its functionality, repackage it, and then ship it. Please let me know in the comments before proceeding with the purchase.
