So I just got off the phone with a guy. I spent an hour on the phone with him. I used my droid the entire time. I was outside, the wind was blowing and it was horrible. as I climbed into the car I asked him if he could hear me better.... He said "I have heard ya fine the entire time, really good quality". He was surprised that I had been out in wind (easily gusting to 20 mph) and all that. Said I must have one excellent phone. To which I replied "Yup, I love my 'droid". The nature of this call? A high level job interview. Yup, Droid Does have good sound quality on a call.
