I picked up some Ty Hi-z 150 ohm earbuds, and frankly, I'm impressed. I did not see that coming. I'm wanting to mostly use these for running. I can't bring myself to cover the pads on any of my cans with sweat. The problem is that they won't stay in my ears, especially the left side. I know I'll get the just get some IEMs responses, but I can't do in ear. Plus, for 20 bucks, these little buds are glorious. So are there any tricks to fatten these up so they stay put? I thought about adding another donut over the existing donut, but I'm worried that might kill the sound. Are there any better / thicker foamies available anywhere? Preferably of better quality, that doesn't tear so easily.
