BASN Bmaster IEM Monitor Earphones

This is the BASN Bmaster IEM monitor earphones.
Purchased in December 2025, I used them almost daily for work, but they are in beautiful condition. They are still usable, but I am selling them because I have purchased different in-ear monitors.

They are clear and very easy to listen to.
Original price: 12,900 yen

The XS size ear tips that I used will be discarded.
All other accessories have been stored as they were upon opening.

There are no smokers in the household, but we do have a cat.
Please understand that these items have been previously owned.
