Fir Audio M3 UIEM
It's not about driver count. Fir Audio's M3 is more proof of that. Innovations by industry luminary Bogdan Belonozhko get the most out of the dynamic driver and dual balanced armatures.
The buzzwords are Tactile Bass, ATOM Vent System and tubeless Direct Bore. These deliver a linear, reference and transparent sound that The Headphone List describe as "vivid, direct and lively-sounding".
Fir Audio's M3 can be made to order in custom (CIEM) form. Please email firstname.lastname@example.org for lookbooks and impressions taking. Otherwise, explore the rest of Zepp's Fir Audio range here or view our other universal (UIEM) options here.
