I just bought a Plantronics M1100 after doing a fair amount of research and knowing someone that already owned one. Paired and connected without any issues. Made a test call to my son to see how things sounded. I couldn't get more than a couple of feet from the phone without choppy sound. Thinking it was the new headset, I tried using an older headset, same thing. If I went into another room, the reception was just aweful.
Thinking it might be the bluetooth antenna, I took off the phone case I got better results but not nearly enough to be satisfied. I hate to think I just found what maybe the only, but important, issue with this phone. I would like to know if this is a known issue and if so, is there is any remedy for this.
