A:AnswerI am a small person and they fit me so I would have to say small, but since they work through the bones near your ears I don’t see why they wouldn’t also fit a large person.
A:AnswerId be iffy on this one. When I've been running, next to traffic and with wind in my ears, it would be hard for folks to hear me. Not sure how it would work if you cut the wind with, say, a helmet and such. But at least my pair picked up background noise too... just recently my Dad had to hang up on me because he could hear a baby crying 4 aisles away from me when I was at Costco.
A:AnswerI was walking outside with 30 mph winds and my husband thought I was sitting in my office! I was then talking to him in the car and the reception as well as the transmission was amazing.
