【Tested and Working】 Purchased last December, it hasn't even been a year. I'm selling these because I recently lost the case. Sale is for the left and right earbuds only. Recommended for those who have lost their earbuds, are experiencing issues, or are worried about pairing if buying a single earbud. (Charging case is not included.) ※Will be cleaned with alcohol before shipping. ■Condition ・Appearance ※Because I handled them very carefully, there are almost no scratches, stains, or minor scratches visible. (Please check the images for details.) ※Original ear tips are attached. ■Included Items Outer box, all ear tips (including the original ones) ※Please prepare a dedicated charging case for charging. ■Battery ※I didn't notice any significant battery drain during the functionality check. However, I haven't performed a long-duration test. Please understand this before considering a purchase. Please note that returns are not accepted to prevent product substitution.
