I don't see them. Could be an upcoming color, or a skin, or it could be the 2013 Red Version with white earpads.

Audio-Technica made a history article about their limited edition colors here: https://www.audio-technica.com/en-us/blog/a-history-of-a-ts-limited-edition-ath-m50x-headphones/

Given limited information, my guess is it's the 2013 red edition but with white replacement earpads. You can buy the stock earpad replacements on Amazon in both White and Black. https://www.amazon.com/dp/B00LID642G/ref=twister\_B00O3O8ZPQ?\_encoding=UTF8&psc=1
