For the ATH-M50x professional monitor headphones and ATH-M50xBT2 wireless headphones, limited-edition color models have been regularly offered, appealing not only through sound quality but also through striking visual design. Starting in 2020, the "M50x Series Limited-Edition Color Voting" has allowed customers to vote online for the color of upcoming limited-edition models, with global participation from fans.

In January 2024, Audio-Technica launched a special website, "LAB M50x," marking the first initiative where fans could contribute directly to the creation of limited-edition models by submitting their own color designs. This platform allowed participants to select from a variety of matte and metallic colors for each part of the headphones, and thousands of fans shared their designs on social media with the hashtag #MyM50x2024. An expert panel, including the ATH-M50x product manager, selected three finalists from a pool of 14,560 submissions, and the final "LAB M50x" design was chosen through a fan vote, garnering 3,127 votes on social media.

The winning design was submitted by Sergio Gamarra, a DJ from Bolivia. Describing his color choices, Sergio explained: “Blue represents confidence, reflecting the quality and reliability of the M50x headset. Orange evokes energy and creativity, capturing the excitement of music. Lastly, gray adds sophistication and elegance, balancing the color palette with a touch of modernity.”
