I would think so. That's a lot of gain to have twixt mic and speaker in
something that small without feedback.
yes..they use delays to stop the howlround, and echo cancellation - DSP
stuff - but even so its a hard call. However any improvement at all would
be useful.

Would it be possible to use an in-ear speaker inductively coupled to a
body-worn microphone/transmitter?

One of my friends had something like that, a huge box on her chest. she used
to insist that folk "Speak to the bosom!".
