SHURE AONIC 215 wireless earphones with sound isolating feature. - Brand: SHURE - Model Name: AONIC215 - Type: Wireless Earphones - Features: Sound Isolating - Accessories: Quick Start Guide Only tested for functionality after purchase. The cellophane tape has been peeled off during the functionality check, but I haven't touched it since. I purchased it 10 days ago, and there is no discoloration on the box or contents. As it is almost a complete set, the price is set a little higher. I am willing to negotiate the price as much as possible. I would like to sell this item quickly. Thank you for looking.
