Super powerful, yet clean bass: FATfreq headphones are renowned for creating the deepest and most physically palpable bass on the market (in some models the boost reaches +20-30 dB). At the same time, thanks to patented technologies, this bass doesn't "bleed" into the mid frequencies, leaving vocals and instruments crystal clear.
Bass Cannon Technology: a special acoustic chamber and crossover system allow for achieving a subwoofer effect that is usually only attainable in full-size acoustic systems.
All headphones are developed and assembled by hand in Singapore.
Maestro in-ear headphones are a versatile workhorse on stage and in the studio, providing a balanced response across the full range with an extended high-frequency range. Thanks to special low, mid, and high-frequency drivers, you can now enjoy distortion-free mixing at full volume with excellent dynamic balance and detail. Maestro is available in both universal and custom versions.
Unmatched high-frequency amplification and control.
Designed for demanding professionals on stage and in the studio, Maestro delivers an unparalleled balance of accuracy and musicality with incredible power reserves. The patented hybrid technology reproduces exceptional low-frequency control, maintaining clarity and detail with precision up to a frequency of 25,000 Hz.
Bass Cannon Technology.
Utilizing proprietary dynamic low-frequency drivers, bass chambers, and acoustic filters, FATfreq managed to create the deepest bass ever recorded - a 20 dB boost, with frequencies below 200 Hz. This is not for the faint-hearted.
Linear impedance.
FATfreq uses proprietary schemes to correct non-linear resistances in multi-driver headphones. Different output resistances of all your devices lead to differences in frequency response. Using this technology ensures consistent frequency characteristics of IEMs when connected to any device - whether it's a microphone block, mixer, phone, or specialized portable player.
Sonar La Trompa proprietary technology.
Inspired by the anatomy of a traditional French horn, FATfreq uses an exponential French horn curve to adjust amplification and enhance tonality of high frequencies through acoustics. It provides smooth, natural sound of high frequencies, backed by pleasant timbre in the mids and lows.
Phase alignment.
The absence of DSP in IEMs means that phase alignment in multi-driver headphones needs to be done with acoustic delay. Using proprietary structures, engineers were able to align low, mid, and high frequencies in a way that they consistently hit your eardrum. Providing the accuracy and sound resolution needed on stage and in the studio.
