Purchased new in October 2025, aged for about 50 hours with aging sound sources, and then listened to for about 3 hours. I used ear tips other than the included ones, so I haven't used the included ones much. However, the S&S ear tips (size M), Candy ear tips (size S), and Basic Balance ear tips (size S) were used to test the fit and are therefore listed as used. All accessories are shown in the photos, and I will remove any that are not needed. Please make reasonable offers regarding price reductions.
