I purchased these new on Amazon and used them indoors for a short time. However, I quickly bought another pair of earphones, so I've been storing these carefully. They are in clean condition with no scratches or stains. The sound quality is also perfect. All accessories are included, and the spare ear tips and charging cable are unused. The ear tips currently attached have been disinfected with alcohol. ◾️Product Description (from the web) ・Equipped with ENC noise-canceling function.
