Thank you for viewing. Final A5000 Operation has been confirmed. I purchased it in December of last year and used it a few times, but it didn't fit my ears, so I'm selling it. There are no noticeable scratches on the main unit. I apologize if I missed anything during my amateur inspection. Please purchase if you understand that this is a used item. Instant purchase is OK. Cancellations due to personal reasons are not possible.
