Michael has a Samsung Galaxy Tablet and when he connects via Bluetooth to his headset, the audio quality really drops. Leo says to try removing the device and then repairing it. It's also possible that the profile Michael is using is the wrong one. The sad part is, Michael may not have a choice to use a different one. So he may be stuck. He will want to use a profile suitable for music, like Aptex or A2DP. But it sounds like the tablet may be older, and thus relies on an older headset spec that doesn't support stereo and won't sound good.
