Audio glitches while playing songs over MOTO S305 headset 

The MOTO S305 doesn't support read remote extended features command.
The fix is we should always use ReadRemoteSupportedFeaturesCommand at first,
Only send ReadRemoteExtendedFeaturesCommand if extend features are supported
by remote device.
