Query: sound is very good but fit is awkward

I bought these after reading the Amazon reviews. The sound through the headphones is good. However, the fit with any of the three different size rubber earbud covers is awkward and the earbuds fall out of my ears when running or biking or weightlifting. Of course, all ear shapes and sizes are different, but I would strongly recommend you attempt to try these for size elsewhere before ordering online.
