To perform your best, hearing high-resolution mixes is not enough - you have to feel it pumping in your veins. Packed with Tribrid technology, Maestro SE utilizes a combination of Dynamic, Balanced armature, and electrostatic drivers for best-in-class airiness on the highs and ultra-highs, supported with a powerful yet controlled low-end for ultimate head-thumping goodness! Now available in Universal-fit.

Maestro SE Defining Bass Excellence

A harmonious blend of extraordinary bass and unmatched clarity that transcends traditional boundaries, with every musical nuance captured and conveyed with authority.

FF Custom-Designed Bass Chamber

Meticulously engineered, the chamber utilizes cutting-edge acoustics to amplify low-frequency vibrations - Setting the benchmark for deep, captivating Bass response.

Precision-Tuned Quad EST Drivers

The Maestro SE is powered by Quad precision-tuned Electrostatic drivers for unmatched detail retrieval and soundstage up to 40kHz and beyond.

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.

3D Contour Fit

A secure fit allows you to get the best out of your in-ear monitors. Using software and earmold retention principles, FATfreq digitizes your scans to shape important pressure points, ensuring your perfect 3D-fit. Models are then sent to FATfreq's high-precision 3D printers for fabrication.
