Ultra-powerful yet clean bass: FATfreq headphones are renowned for creating the deepest and most physically palpable bass on the market (in some models, reaching up to +20-30 dB). Thanks to patented technologies, this bass does not interfere with the mid frequencies, leaving vocals and instruments crystal clear.
Bass Cannon Technology: A special acoustic chamber and crossover system allow to achieve a subwoofer effect usually only possible in full-size acoustic systems.
All headphones are designed and assembled by hand in Singapore.

A project born from the intention to create a monitor that meets all the requirements of the flagship MAESTRO series, all at an affordable price. This low-frequency IEM is the benchmark for all Basshead audiophile audio systems.
The unique Maestro Mini design provides concentrated reproduction of low frequencies in the sub-bass range without unwanted transitions to mid frequencies. As a result, the model has earned its place as a benchmark for music lovers and bass guitar enthusiasts seeking uncompromising sub-bass sound.
Acclaimed standard in bass-oriented speaker systems
Continuing to exceed expectations, the Maestro Mini immerses you in the depth and clarity of bass like never before. With FATfreq innovation, for the first time developed and perfected to provide incredible bass power. 3D-printed sound channels and a signature bass chamber tuned for perfect control.
Low-frequency chamber
In a meticulously designed chamber, state-of-the-art acoustics are used to amplify low-frequency vibrations, setting the benchmark for deep and mesmerizing bass sound.
Bass Cannon Technology

Используя фирменные динамические низкочастотные динамики, басовые камеры и акустические фильтры, компания FATfreq смогла создать самые глубокие басы, которые когда-либо были записаны, - повышение на 20 дБ, с частотой ниже 200 Гц. Это не для слабонервных.
Linear impedance
FATfreq uses proprietary schemes to correct non-linear resistances in multi-driver headphones. Different output impedances from all your devices result in differences in frequency response. Using this technology ensures consistent frequency response of the IEM when connected to any device, be it a microphone block, mixer, phone, or specialized portable player.
Signature Sonar La Trompa technology
Inspired by the anatomy of a traditional horn, FATfreq uses exponential horn curvature to adjust gain and improve tonality of high frequencies through acoustics. It provides smooth, natural high-frequency sound, supported by pleasant tones on mid and low frequencies.
Phase alignment
The absence of DSP in IEMs means that phase alignment in multi-driver headphones needs to be adjusted using acoustic delay. Engineers have aligned low, mid, and high frequencies so they reach your eardrum in a coherent way, providing the accuracy and resolution of sound required on stage and in the studio.
Silver cable
Custom-made Type-6 Litz pure silver cable to enhance the power and responsiveness of your mixes. Included are interchangeable 2.5mm, 3.5mm, 4.4mm audio plugs to choose the sound source.
