I purchased these at e-earphone, intending to use them, but I never got the chance, so I'm selling them. I opened the outer box, but the item itself is unused. They have been stored carefully in a dark place, so the condition is very good. The conversion nozzle adapter is also included. Please feel free to ask any questions in the comments.
