Through a couple of different pairs of BT earbuds, none have done a really good job at managing phone calls on the bike-- not the fault of the headphones at all, and 100% the wind noise-- but I am generally doing +15mph.

For talking while in motion, corded will always work better because it (generally) puts the mic closer to your mouth. For phone calls at speed, aside from going to a lavalier mic, the audio for people on the other end is never gonna be very good.

If the call is important, I'll pull over. The call is seldom important.
