I've tried over 5 BT earpieces and I haven't found one that's comfortable on a bike either because they're too big and conflict with helmets straps or get sweaty and eaither slip off of just are plain uncomfortable. Plus it's yet one more gadget to remember to charge up. Wired headsets are smaller but the wire is a problem, of course, for any physical activity. I'm lucky though, I'm not a heavy phone user. I just have my phone clipped to my clothing in some accessible place. As mentioned above, you could clip it to the handlebar. I'd just be worried about damaging it.
