Final Fusion-G Black, Size M: Foam and Silicone Fusion

This is a black, size M of the final (ファイナル) FUSION-G.
Purchased in April 2026, it was intended for use with the final A4000.
However, the shape differs from the genuine ear tips for the A4000, and they did not fit my ears, so I am selling them.

One pair was attached to the A4000 and inserted into my ear only once, for just a few seconds (the pair on the right in the photo). I disinfected it with an alcohol wipe just in case.
The other pair is brand new and has not been touched at all.

Thank you for your consideration.
