Silicone is a cute, for sure!
Mine are placed in two short (3cm each) PU-tubes of two different diameters.
The bigger one's hole is drilled exactly to the AOM5024 diameter. So I can press it in and it's absolutely tight.
The smaller one fits exactly inside the bigger tube's other end. It's inner diameter is 6mm, and I pressed a 3,5mm TRRS-jack (wich is also exactly 6mm in diameter) inside after soldering the cables.
After mointing the PU-tubes I wrapped camouflage around. That's it.
One problem with TRRS-jacks for mics is, that you will disconnect the internal speaker, as soon as you plug the mic in.
To solve that, you habe to bridge the speaker's contacts inside the microphone's TRRS-jack
