I hesitate to put Audeze on the spot as I also haven't seen an official release announcement, just a tweet they posted. So I may or may not have received a pop filter from them.
Being a small company, they'd likely not want an influx of requests, but their customer service is top-notch so it wouldn't hurt to send a polite enquiry.. if your mic is truly suffering.
Thinking back, it was the same procedure for the beta firmware. They really try to go the distance and help their customers, unlike any other company I've dealt with in the past. Love these guys.
Edit: just found that tweet. And they replied to someone: "it is already available. please email support@audeze"

Thanks for the heads up! I was expecting them to make an announcement when the filters were available. Odd way to find out....but I emailed them just the same.
