Super powerful, yet clean bass: FATfreq headphones are known for creating the deepest and most physically felt 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 achieve a subwoofer effect usually only found in full-size speaker systems.

All headphones are designed and assembled by hand in Singapore.

The Musician Pro in-ear headphones are a versatile workhorse, perfect for multi-instrumentalists, providing a balanced response across the full range with deep bass. Special low and high-frequency drivers allow for distortion-free mixing at full volume with excellent dynamic balance and detail. Musician Pro is available in both universal and custom fits.

Linear impedance

FATfreq uses proprietary schemes to correct nonlinear resistances in multi-driver headphones. Different output resistances of your devices lead to frequency response differences. This technology ensures consistent frequency characteristics of IEM when connected to any device – whether it's a microphone block, mixer, phone, or specialized portable player.

Signature Sonar La Trompa technology

Inspired by the anatomy of a traditional French horn, FATfreq uses an exponential French horn curve to adjust amplification and improve tonality of high frequencies through acoustics. It provides smooth, natural sound of high frequencies, complemented by a pleasant tone on mid and low frequencies.

Phase alignment

The absence of DSP in IEMs means phase alignment in multi-driver headphones needs to be achieved through acoustic delay. Using proprietary structures, engineers were able to align low, mid, and high frequencies so they consistently reach your eardrums, providing the accuracy and resolution required on stage and in the studio.
