My right ear was at 10mm and left ear at 12mm, i'm downsizing my ear for a job.
My left ear is currently at 6mm, and my right ear is at 8mm.
How do i downsize to 6mm for my right ear?
I want both of them to be equal.
Small sized plugs are allowed in my work area.
So 6mm should be fine.
How do i make sure my right ear goes to 6mm and not smaller then that?
