Astro A30 mic replacements

Hey, I've had the astro a30 for a while, the Xbox one, I don't think it makes a difference though. I mainly use it on Xbox though and here's my issue.

My microphone, the boom mic, recently gave out, and the internal mic is too low quality for anyone to reliably hear me. Is anyone aware of a replacement microphone for this headset? I'm in no financial spot to buy a new headset right now, so I'm stuck with this. If anyone knows of a decent alternative, please let me know. I'm desperate.
