SHURE AONIC 215 Wired Earphones Purchased one year ago, used for a few minutes 1-2 times. Operation confirmed, works perfectly. No noticeable dirt or scratches. While I have cleaned the surface for sale, I haven't been able to check the fine details or parts that require disassembly. Please refrain from purchasing if you are looking for a perfect product. Returns and exchanges are not accepted. Thank you for your understanding.
