Purchased used in September 2023. I am selling these because they don't fit my ears. Functionality has been confirmed. I used them for about 2 hours, and the earphones themselves have no noticeable scratches and are in excellent condition with little sign of use. The left and right numbers are 065. All accessories are included except for the instruction manual. To prevent swapping, returns are not accepted, so please consider this item if you understand that it is a used product. Same-day or next-day shipping is possible. SHURE AONIC 4 SE42HYBK+UNI-A Black Wired Earphones with Microphone 3.5mm jack MMCX detachable 3.5mm Thank you for viewing.
