Disappointed by build

This review is based upon a replacement pair of headphones. The original pair ordered had the right ear piece acting up where the right ear ANC would cut in and out sporadically. After 2 days, all sound would cut in/out. I returned and they sent me a new pair. This one lasted longer, about a month before the ANC had issues. They still play music fine however. I will not be getting another pair of these. The sound quality is great and they are very comfortable but the longevity thus far has been lackluster.
