I love my Airpods. One of my favorite products of all time. But I've found them to be totally useless on calls. I'm on my third pair -- that's another thing: they wear out if you use them a lot -- and I've had 3 different phones in the meantime and nobody can ever hear me when I talk on them. I've tested it myself and they make the speaker sound very quiet and far away. It must not affect everyone, because I see people using them for phone calls, but I've never been able to make that function work.
