Super powerful yet clean bass: FATfreq headphones are renowned for creating the deepest and most physically impactful bass on the market (in some models, the boost reaches up to +20-30 dB). Thanks to patented technologies, this bass does not "bleed" into the mid frequencies, leaving vocals and instruments crystal clear.
Bass Cannon technology: a special acoustic chamber and crossover system allow for a subwoofer effect usually only achievable in full-size speaker systems.
All headphones are designed and hand-assembled in Singapore.
The in-ear Musician Pro SE headphones are a versatile workhorse, perfect for multi-instrumentalists, with a balanced response across the full range and deep bass. With special low, mid, and high frequency drivers, you can now enjoy distortion-free mixing at full volume with excellent dynamic balance and detail. The Musician Pro is available in both universal and custom fits.
Unmatched low frequency amplification and control.
The redesigned Musician Pro instrument, created for bass guitar enthusiasts. A pronounced V-shaped curve with unparalleled bass extension and control. In combination with the unique three-way crossover, the Musician Pro SE is equipped with an additional low-frequency driver, providing deeper and richer bass with seamless transition to the mid ranges.
Linear impedance.
FATfreq uses proprietary schemes to correct non-linear resistance in multi-driver headphones. Different output resistances of all your devices lead to differences in frequency response. Using this technology ensures consistency in the frequency response of IEMs when connected to any device - whether it's a microphone block, mixer board, phone, or specialized portable player.
Sonar La Trompa proprietary technology.
Inspired by the anatomy of a traditional French horn, FATfreq uses an exponential curve to adjust amplification and enhance tonality of high frequencies through acoustics. Provides smooth, natural sound of high frequencies, supported by pleasant tonality in the mid and low frequencies.
Phase alignment.
The absence of DSP in IEMs means that phase alignment in multi-driver headphones needs to be achieved using acoustic delay. Using proprietary structures, engineers were able to align low, mid, and high frequencies so that they reach your eardrums cohesively. Providing the accuracy and resolution of sound required on stage and in the studio.
