@sam I have #threema for select buddies only... perhaps ticks the boxes?

Anyone know of a reliable #microphone and how to use it for #telephoning with decent sound quality, using a smartphone, while #cycling ? I can #telephone in the car fine but on #bike I have to abort most calls. Is there a trick or #gadget I can use to have decent #soundquality without #wind and clothes rubbing mic and background noise etc.?
Do I have to wear a #motorcycle #helmet for the #soundquality ?
Thanks for sharing any tips!
