Purchased in August of this year. I'm selling it because I quickly switched to a headphone setup and haven't used it much. It was glass coated immediately after purchase, but it's a thin coating for smartphones, so the effect may not last long. Masking was done during the coating process, so there's no impact on vent holes, etc. Apparently, there are variations in the resin, and there are parts that look like scratches, but I think it's in better condition compared to other units. The box also has some original scratches, etc. The cable was only used for a functionality check before packaging and is practically unused. I also used my own ear tips. There are two pairs of size M ear tips in total, one pair that was originally attached to the unit and a spare.
