I would recommend whatever you can afford from Shure. I bought one pair several years ago for about $100 and the quality was absolutely superb. They come with tons of choices for the foam inserts, and their customer service is great. I had mine in a bag with some takeout and some ocra juice got in and totally muffled one of the buds. Sent them in expecting to have to pay, but they sent me a brand new pair no questions asked. I ultimately left them on a plane like an idiot and picked up a newer, better pair off ebay for about 150 and the sound is astounding. Plus, with the newer ones the drivers actually detach so if something happens to your cable and can replace it for a fraction of the cost of a new set.
