Experience raw, unadulterated power with the World's First 30dB sub-bass shelf, expertly controlled under 200Hz. FATfreq's proprietary tubeless hyper tweeter system provides stratospheric ultra-high extension and brilliance to 40kHz. Giving you the best of both worlds at incredible value and ergonomics.

FF Custom-Designed Hyper Tweeter

Engineered for absolute clarity, FATfreq's tubeless hyper tweeter system provides ultra high-end extension and brilliance to 40kHz. All Acoustics and Technology is packed into an astoundingly ergonomic shape for your perfect, non-fatiguing fit.

Bass Cannon™

Using proprietary dynamic woofers, bass chambers and acoustic damping networks, FATfreq was able to design the deepest bass ever recorded of over 30dB, expertly controlled below 150Hz with zero mid-range bleed. A FATfreq innovation pioneered and perfected for sheer bass power.

Linear Impedance

FATfreq uses proprietary circuits to correct the non-linear impedances of multi-driver systems. The different output impedances across all your devices cause frequency response to vary. Having this tech ensures consistency in frequency response for all FATfreq IEMs when plugged into any device - Be it your mic-pack, mixer board, phone or dedicated DAP.

Sonar La Trompa™

Inspired by the anatomy of the traditional french horn, FATfreq uses exponential horn curvature for gain control and to improve treble tonality via acoustics. Providing you with Smooth, natural sounding highs, grounded by a nice timbre in the mid and low frequencies.

PhaseAlign

The absence of a DSP in IEMs means that we have to match the phase of multi-way systems via Acoustic delay. Using proprietary structures, FATfreq was able to align the low, mid and high frequencies such that they reach your eardrum in a coherent manner. Giving you the sound accuracy and resolution demanded on stage and studio.
