The corrosion from alkaline batteries is hard, tenacious and incredibly
difficult to remove if you use conventional organic solvents and
cleaning agents.  The magic substance, which works wonders, is water: a
slightly damp cloth or cotton-wool bud softens the corrosion and wipes
it away.  Clean the terminals on both the battery and in the device,
then make sure they are completely dry before putting the battery back
in.

No, the terminals on both the new batteries and the old ones (when i put
them back in) seem reasonably clean.

The corrosion is invisible, so a clean-lookig terminal may still have a
semi-insulating layer which is too hard to rub or scrape off without
damaging the plating.

First everything worked for two days after changing the battery.  Then one side started to give the high pitched whine. Then the sound on that side died. completely.
 During this perood of  testing, I noticed that the new batteries only lasted an hour or so.
 So I put the original batter daies back in.  The dead side is no better but after 4-5 days,  the one working side went dead.
Mind you, - even when dead with no sound, bothbuds report power properly on the bt side!
 Then yesterday, the sound on the working side went dead!

Could be earwax buildup in the buds.  Builds up slowly over months at roughly the same - but not _identical_ - rate in each side. That seems
to match your symptoms with the original batteries: first one dies,
then after some indeterminate elapsed time the other dies with no
sound but batteries measure good.
