So far they're great...with the Comply tips they isolate very well and are very comfortable as well. The detail is amazing, and the soundstage is about the best you can expect from a universal IEM. Separation, as expected with a 3 way crossover high-mid-low setup, is great. Can't recommend these enough, and at the prices these are going for now you'd have to be crazy not to buy them.
Best headphones for the money
