Thank you for viewing. I purchased these about six months ago and used them a few times a month on my days off. I'm selling them because I no longer use earphones. All the accessories are included, and I haven't experienced any problems with their operation. Since I'm not very knowledgeable about speakers and audio equipment, and these have been handled by someone else, I'm selling them as junk.
