If you are interested in KOSS disclosing DRS numbers to the public, you may want to consider emailing their investor relations to let them know

Every 3 months, KOSS puts out a 10-Q report. KOSS could easily include the DRS numbers like GME does (see below). KOSS email info I found online is: mjkoss@koss.com

KOSS is a small family business and I believe that just a handful of emails from passionate Koss shareholders could have a big impact. Keep in mind that public companies are not allowed to disclose shareholder owership that is held in street name with brokers, BUT they are allowed to communicate with and report ownership from their transfer agent regarding direct registered shares.

For reference, here is how GameStop worded it on their last 10Q. There will be another update tomorrow as that's when their 10-Q comes out.

"As of April 30, 2022, 12.7 million shares of our Class A common stock were directly registered with our transfer agent."

You can see it here at the bottom of page 10:
