You are correct i'm sure, sorry was just trying to help anyone with an older 1st or 2nd gen who came across this thread and wanted to have something similar to the newer 3rd gen models. I know that the older gen bluetooth did not support music over A2DP and just supported calls.
Note: If you are an admin and think it's not relevant please delete my posts.
haha no worries mate. I'm sure it might help someone
