I'm between klipsch and Sennheiser, any guidance.

I bought the sennheiser Adidas sport model in Hong Kong for about $120 USD. The sound was very good and I liked the fins that help the buds stay in your ears. The only problem is they shorted out from sweat. I had the same problem with the pair that came with my iPod shuffle. That's why I went with the adidas sport model. Anyway, after about 3 weeks of wearing then when I run they started shorting out, volume would go up, down, it would skip around to different songs, etc.

I was looking at those. That's about where I'd like to be on price as well.

Just received the etymotic mc3, very nice sound and very comfortable. Nice fit in the ear and stay in place. Just missed a phone call in the house so they must work pretty well at blocking external sound at moderate volume.

Vmoda - real nice sound and fit comfortably in the ear canal without sliding out. They were a little over $100
