[AC Question]

I have a Galaxy Note 2. I have bought two different sets of Bluetooth headphones, (MPow and Jabra) and get get only 10 minutes into a playlist before the music starts chopping up. it happens with both sets, but not the old school wired type of headphones, a small speaker that plugs into the headphone jack, or the internal speaker. My workarounds have been to turn Bluetooth off and back on, or turn the headphones off and back on (both really annoying during a cardio workout). The workarounds only resolve the problem for a shorter period of time. Is there a setting I have missed or is the problem with Bluetooth design/capacity/tech age of the phone?
