Thank you for viewing. This is the "TriMonster (Q-16)" earphones from ivipQ, featuring dynamic drivers. It has high ratings on X (formerly Twitter) and other platforms, and the retail price seems to be around 10,000 yen. I am selling it to organize my collection as I have too many earphones. After purchasing it new, I believe I have only used it for a total of 2 hours, twice, to check the sound quality. There are no scratches or stains, and it is in very clean condition, almost like new. The outer box is not included, as it was not present when I purchased it new. 【Condition】 Usage time: Less than 2 hours (only 2 listening sessions) Product condition: Almost unused
