I purchased these high-end earphones new and have only used them at home. I didn't use them very often, but they are about two years old, so the battery has deteriorated. There are almost no scratches, and the appearance is clean. The sound is still good, with a rich tone, and I always felt that string instruments sounded beautiful. I'm not sure what size the ear tips are, but one size is missing. The charging cord is also missing, so please prepare one. Accessories include the original box, four sizes of ear tips (probably missing M size), and the earphones themselves. I will clean them before shipping. Please note that the condition is based on my subjective assessment, and these items have been handled by someone else. Please carefully check the images and purchase only if you are satisfied. The color may also appear different depending on your monitor and the lighting during photography. I will post plenty of images to show the colors as accurately as possible, so please understand before purchasing. These are used, discontinued, and unsupported products, so please understand that they are sold as-is, with no returns or claims. Also, in the case of used clothing, we do not accept complaints about odors, so please purchase only if you understand this.
