I purchased this item new and used it, but I am selling it because I received a higher-end model. I lost the left earphone, so I purchased a replacement left earphone on this site. Pairing works without any problems, and there are no issues with playback, but if you are concerned about this, you may want to refrain from purchasing. I will include the instruction manual, charging cable, unused earphone tips, and the separate body from when I purchased the left earphone. I will answer any questions, so please ask before purchasing. #Anker #SoundCore #Earphones
