Save some money and get some excellent headphones.
These headphones sound VERY good! They don't have some of the features of the XM5s, but they share the same active noise canceling, which is also VERY good! I highly recommend these. For under $100 you can't go wrong.
These headphones are amazing!! Sound quality is just as good as sony's newest more expensive headphones and the features are all perfect. Comparing it to sony's newest $400 headphones, I say these are nearly as good for a quarter of the price. One thing to note if you are comparing is that the noise cancellation is not as good. Still works okay and I am happy with it but it is of lesser quality than more expensive headphones. But that is the only thing I can think of!!! super comfortable and the battery lasts forever. Highly recommend!
