Anyone use these? http://hearos.com/earplugs/products-00211.html I tried out the Hearos Rock N Roll ear plugs last night and was pleased. I'm wanting to try out the High Fidelity ones but one thing makes me hesitate. When looking at the product picture, it looks like it has tubes extending out. Not sure I want to have tubes sticking out of my head when playing live. Any feedback would be appreciated.
