There is no way that you can use a boom mic with a petrol engine! The
vibration will couple directly through the fuselage attached boom and
produces a huge signal. The use of ear-buds is a great idea, but the cost
is somewhat eye-watering! I just use the cheapest Ebay aviation headset
which will collapse to a reasonable size, unlike the premium headsets.
Anyway, its is very difficult to converse with a self-launching 2 stroke at
+6000rpm just behind your head, however much you pay for a
headset/whatever.

They are an excellent way to scratch the inside of the canopy. Also
something to store when not in use, which is 95% of the time as I recall.
There are many "isolating ear bud" headphones available these days.
Examples:

Shure

Ultimate Ears

Ear buds are available from manufacturers or on Amazon, etc. for much
less
than an aviation headset, and fit in the glider's side pocket.
Install an 1/8" stereo headphone jack and use the same boom mic!
