Bose noise-canceling headphones, the QuietComfort 25. Sound output is good. There are no issues with left/right sound positioning. Noise cancellation has been confirmed to be working properly. While it's an older model, it's in relatively good condition, with minor scratches and scuffs. The ear pads likely need to be replaced. All accessories are included. It seems you can make it wireless by purchasing a kit. This is a rare and excellent noise-canceling model that runs on AAA batteries.
