Purchased online on October 1, 2025, and used mainly on weekdays for about a month. I am selling this because I plan to switch to the manufacturer I used previously, due to personal preference. The sound quality and noise cancellation are surprisingly good. There are no noticeable scratches or stains on the case/main unit. All accessories are included, including the box, but please understand that this is a used item before purchasing. The charging cable is unused. There are no delivery notes or receipts (due to online purchase), but Bose doesn't even include a paper warranty, so I believe the serial number will likely provide a one-year warranty (I haven't tested this, so I can't guarantee it).
