The reviews also seemed consistently good. Sleeping became difficult as any pressure would cause the ear to throb. So I sent in for the upgrade, giving them my numbers on the unit as they asked. Definitely would not fit a size 5 or 6. And also stainless steel bench top in the garage. I purchased a day before Christmas and it has been even one month. you wanna ride the bike gets old very quick. My biggest concern was battery life (because I wear headphones my whole 8 hour shift and that was by far the most crucial factor for me) and using them a couple weeks here are the very encouraging and satisfying details:1) Each bud last about 3 hours give or take a few minutes. Convenience? removeable mic ? this is nice if you just want to use the wireless headset to listen to music. Still havent heard back from them.
