Japan genuine product FiiO K15 Silver

This is a genuine Japanese model, the Fiio K15 in silver, purchased from Amazon (sold by e-earphone) in September 2025.

I purchased it, but it's difficult to continue using it as the size doesn't fit my environment, so I've decided to sell it.
I am not considering price reductions for the time being, so please refrain from price negotiations.

Please only purchase if you understand that this is a used item.
Everything shown in the photos is included, and I cannot answer questions about the warranty.

I plan to ship it in the original cardboard box shown in the last photo.
