High-quality wireless earbuds with a stable fit. - Brand: audio-technica - Model Name: ATH-SQ1TW - Color: Blue - Features: High sound quality, stable fit - Type: Wireless Earphones Purchased in 2021 and used for about 2 years. The main unit has been cleaned with an OS cleaner, and the ear tips (large) have been replaced with the unused ones included (photos 3, 4). Therefore, there are two pairs of small-sized replacement ear tips remaining (photo 5). Part of the box is damaged and stained (photo 6). Pairing operation has been confirmed with my personal smartphone. We have made the price more affordable than the market price for used items, so please refrain from price negotiations.
