I've used these for about a week, but they didn't fit my ears, so I'm putting them up for sale. 【Included Items】 Everything shown in the photos. (Main unit, case, instruction manual, different sized ear tips) Different sized ear tips are included (second photo, right side), but I mistakenly opened the plastic packaging when I bought them, thinking they were spares. The ear tips inside are unused. Please understand that these are used items, despite the short period of use, before purchasing.
