they collapsability be great for portability and store on trip , and the mechanical design appear to be durable over time - ask I again after five year of hither-and-yon . sound quality be fine . not exceptionally comfortable after a extended sit , compare with a studio-quality headset , but that comparison be unfair since they be not intend for that use . only complaint be the lack of a adapter to 1\/4 '' phone plug socket .
