I purchased these for use in online meetings and used them once just to try them out, but I'm selling them because I'm using other earphones. Purchased in August 2024. All accessories are included. I am not currently considering lowering the price. I would appreciate it if you could understand that these have been stored at home. To prevent swapping, returns are not accepted.
