How to fix music cutoff problem while playing music with bluetooth headset

Last year when iPhone OS 3.0 released, it enabled iPhone users to use Bluetooth and stereo headsets with A2DP and but not fully ARCP protocols. We took a look at the Motorola S9 Stereo Bluetooth Headset for iPhone 3.0 previously and now looks at the Motorola MOTOROKR S9 HD and has found it offers exceptional sound.So far it was working great for me, but recently I found out one issue while playing music with MotoRokr S9-HD that as long as the screen is on it plays fine, but once it goes off to conserve battery the music cuts in and out, mostly out and I was quite pissed off !!! almost planned to do a complete restore but before that I googled out and found out that the solution.
I just reset the Network settings by Going to Settings>General>Reset>Reset Network Settings, and it fixed the problem. Though I couldn’t find the exact cause of this, but I thought that sharing this info will be useful for you.
