I have a Droid DNA but a friend just bought the ONE. Nice phone but he is having a terrible time finding a bluethooth headset that will work well without background noise. It took me 2 yrs to get him away from his Iphone so help me to not loose him back to the dark side.... I do not use bluethooh headsets as I just ignore the phone until I arive at my destination, so I'm clueless. He has tried a Plantronics Voyger 510 that worked perfectly for his Iphone but it was really bad with the ONE. He can hear people well enough but the background noise for those calling him is incredible. He recently used a different Plantronics model but it was only slightly better. Any Recommendations from those who have used both in conjuction with each other would be much appreciated.
