Purchased at e-earphone at the end of July this year. The original price was 570,000 yen, so it's a great deal for those who already have a cable. The invoice will be included with personal information redacted. The used warranty period has several months remaining. This is a collaboration between Astell&Kern and Empire Ears. I really liked the sound, but it didn't fit my ear shape, so I'm selling it. Operation has been confirmed. The main unit is in very good condition, and there are no noticeable scratches. For an additional 90,000 yen, I will include the Effect Audio Fusion 1. -------------------------------------------------- The following is quoted from my profile: I use recycled cardboard and cushioning materials for packaging. I do not have any pets, and I do not smoke. If you have any questions, please feel free to ask. Below are items I plan to list.
