Fir Audio M3 CIEM
$1,799
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".
Please email crew@zeppelinandco.com for lookbooks and impressions taking. M3 can also be bought in universal (UIEM) form. Otherwise, explore the rest of Zepp's Fir Audio range or view our other custom (CIEM) options here.
