iPod earbuds for exercise

Does anyone have any suggestions for earbuds that are good for running in particular? I was set to order the Shure E2C or 3C, but I don't know how they would stand up to sweat and I am not sure I want an enormous level of ambient sound reduction for safety reasons on the roads. Thus, I am more concerned about fit and durability over sound quality. Thanks.
I hadn't considered that the Shure's might be noisy; thanks for that note Marco.

From the input from those who do use them during athletic endeavors, sounds like this may not be as much of an issue as it is just sitting still in silence. I use mine to listen at night when my wife is reading so it is mostly silent and I am concentrating on the music. Yes, that does definitely make the sound of my own movements more pronounced. Perhaps the effort of running would make that a moot point as your concentration is elsewhere. I play racquetball and I haven't bothered trying out the Shures in the racquetball court. Don't hold your breath for my review on that application either. Oh, and I'd completely agree that the earbuds Apple ships iPods with are best utilized to tie off your trash bag before disposal. The Shures, at least the e4c's, are a world apart.

I own the ec3s but for the gym I prefer these Black mega bass Sony ear buds They sound great and i dont worry about losing a $ 200.00 pair at the gym. They last about 6 months and cost 19.99 at jandr music world. I have been trying to find a pair that sounds better but cant. I bought the $ 70.00 list Sony buds and these for $ 20.00 sound better the more expensive ones for some reason do not go loud enough. I am open to trying any other earbuds. I am demoing a pair of Phillips Surround earbuds $ 20.00 at Best Buys and they are OK too. If anyone knows of a better bud please let me know price is not an issue.
I would like to recommend to you this naenka tws earbuds that I am using now. It uses Qualcomm 3040 chip and Bluetooth 5.0 technology. It can be used for 7 hours on a single charge and the total battery life of the charging compartment exceeds 28 hours. It is suitable for traveling and business trips. Music needs.
