These are the latest BOSE earbuds (2nd generation). I've only used them once to listen, but I'm selling them because the sound quality isn't to my liking. They are like new, with no scratches, but please refrain from purchasing if you are concerned. The next-generation QuietComfort Ultra Earbuds are recommended for those who want to listen to music anytime, anywhere. They feature personalized sound with CustomTune technology, noise cancellation, and a comfortable fit. You can enjoy impressive sound in various environments without compromising on sound quality.
