I'll get in touch with Audio Technica and see about sending it in for an eval.
It didn't cut out entirely, it just got quieter and the bass disappeared. When I plugged it in later, it worked as expected. However, it might be brighter than it was before, and maybe a touch less sensitive. I guess that fits in with the "less low-frequency response" since I turned it up to compensate and heard more highs. I can't tell for sure since I was just talking into it, listening on headphones (not something I do regularly, so I don't know what that should sound like).
Thanks for the info J.J.!
