FIX BOSE Headphones with A Hairdryer!! QC25 noise cancelling

Without a Hairdryer I couldnt get the glue of the earpiece speaker...
Remember the BOSE QC25s that let me down on a flight? I purchased a speaker for the QC25s and got around the glue problem with a hairdryer ... another bit of Dubious Engineering!!
Changing the channel slightly - please be patient ...
(None of the work on this channel is of real engineering standards - that said, the headphones actually sounded as they did before they broke - I'm actually a happy puppy!)
