I'm amazed that people try to use large headsets in Self-Launch Sailplanes.
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!

I use a boom mike and a compact headset with no mic.
Of course, my Antares 20E is much quieter than other motorgliders.

One of my friends is very happy using Bose noise-cancelling
non-aviation earbuds in his (louder) ASH-26E with a boom
mic.

Neither of us switch microphones...

Hope that helps,
