Our C4A hosts 4 balanced armatures per side (1 low, 1 mid, 1 mid-high and 1 high), and is the go-to choice for many musicians who prefer a bright, crisp frequency response through the mid and high range.

The C4A is beautifully clean and clear, with tight low end. A favourite choice for strings, keys, brass and woodwind players, as well as vocalists.

    Order Notes

SAMS

Our innovative Solid Acoustic Mass Shell provides enhanced isolation, fit and durability.

ModTec

Our proprietary balanced armature driver format. Extensive R&D has allowed us to package our individual drivers and crossovers into one solid module. The same tried and tested Cosmic Ears sound, from one source.

SDM

Our Shock Dampening Membrane works in unison with SAMS, the SDM is another layer of protection that defends our ModTecdrivers from the rigours of everyday and on-the-road life.

PPA

Pro-Phase Audio delivers industry-leading flat phase response so all of our ModTec drivers work in perfect harmony.

TunR

All our configurations are designed using our custom-built development chamber which allows the sound to be designed in unison with the resonance of the ear canal.
