Have now had the headphones for a year and a half. They still work well after using them every day for a year and a half, but about six months in, I noticed that they "crack" when you put them on or if you sit and eat at the same time. No huge concern but may be worth mentioning as I am not the only one who has experienced this "problem"
+ good sound to be noise canceling headphones
+ good bass
+ really good noise canceling (may be the best on the market in this price range)
- box microphone
