Fir Audio M3 CIEM
It's not about driver count – Fir Audio's M3 is more proof of that. Innovations by industry luminary Bogdan Belonozhko such as Tactile Bass, ATOM Vent System and tubeless Direct Bore get the most out of the dynamic driver and dual balanced armatures put to use delivering a linear, reference and transparent sound.
Please email email@example.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.
