Query: Great Earbuds!

They really sound fantastic, I wish the design were better so that they stayed in my ears more firmly when I run. The noise reduction really works (you'll have to take them out of your ears when someone starts talking to you). Just remember its noise REDUCTION and not CANCELING. I got about 3 months of use out of them. But thats how long my earbuds usually work until one of the ears stops working or you need to wiggle the port to get the sound right.
