Early teaser image reveals a striking retro-inspired design featuring a vibrant transparent orange plastic shells and stem, matching orange foam covers, and a classic fixed, non-detachable cable setup. While technical specifications, driver details, and the official model name remain under wraps, this release marks an exciting expansion for the brand beyond their traditional in-ear monitor lineup.
