A five balanced armature universal IEM from Heir Audio and the first five driver universal IEM in the world. Featuring a warm, lush, impactful low-end coupled with non-sibilant highs. It was built in response to requests for a “universal 8.A.” The name was inspired by the 1987 Ford Mustang 5.0 which marked a return to raw power, the Heir Audio 5.0 does the same. It also marks the introduction of a refined shell designed in collaboration with a fellow Head-Fi member.
