I own a Zebronics headset and after trying a lot of options I found one that works for me. My device is Samsung Galaxy S7562
1) Make sure u enable bluetooth (Settings---->Bluetooth----> Slide the bar to the right and it glows green, this shows that Bluetooth is on in ur mobile)
2) Select Bluetooth (Settings--->Bluetooth--->Make ur device visible, by default it is GT-S7562)
3) Switch on ur headset, it shows up on the ;list of available devices, if it doesn't show up, Click the Scan button on ur mobile screen and find and pair ur headet to mobile
4) Once it is paired and connected, U have a few more things to do before u can listen to Music from ur headset
5) Download Bluetooth Manager ICS from Google Play Store
6) Download Rocket Music Player form Google Play Store (any player other than the one that came with ur mobile and Google Play Music is supposed to work but I use Rocket Music Player)
7) Open Bluetooth Manager and U will find a checkbox next to a "Select Filter" button. Tick this checkbox and minimise the app but do not close it
8) Open Rocket Player and play any song u want, U will hear it through ur bluetooth headset and not out loud.
Enjoy!!!
