Thanks for the input everyone.
@Dan Dare, the necessary part -- a replacement microphone and boom -- is available but is nearly £74 with VAT. I don't know if it's a screw connection internally or needs soldering and past experience says I'm no good with a soldering iron. Replacement headsets--some 'little used'--are available second-hand for less than the cost of a boom...
I'm weighing up the pros and cons.
