I decided to make them because my ear buds hurt my ears after wearing them for any more than an hour (which I do all the time when I travel). Anyway, I've worn them for over an hour once so far, and they are totally comfortable. Cool thing is, I can pop the ear buds out pretty easily, and could probably switch in a nicer set of buds without a problem. It's worth doing IMO.
P.S. My life is back on the strait and narrow after a few rough months were I didn't want to do anything, so expect me to be blogging and writing code, and doing a ton of more projects this summer. Next up is making some carbon fiber shiznit for my KTM.
