I add foot powder and spray them but still. But that is covered in other reviews. Das ist wie laufen auf Wolken. It took about an hour and required only a hammer and a Philips head screwdriver (Id recommend using an electric screwdriver to speed things up). If youre like me, I always keep my phone on Vibrate mode. I looked through all the headphones packs, and this was only on one of them. The only noise I hear is from the tire on the roller and the bikes drive train. Did my research on earbuds and these kept popping up as highly rated. PERFECT. I would even buy a Sony underwear without batting an eyelid if they ever launch one.
