I've had my HTC one with Sprint for just over a week now and noticed something. About 1/3 of my calls to friends sound far away. It is almost like the other person is speaking to me through speaker phone or is talking to me through an elevator shaft. I love this phone, but not sure why some of my calls dont sound great through the ear piece. I had the 3VO before this and never had this problem. Is the beats speakers messing with my normal call speaker? My best friend also has the One with Sprint and said his does the exact same for about 30% of his calls. Anyone else experiencing the type sound quality while on calls?
