FATfreq Tech

BASS CANNON™ (Patent Pending): Using proprietary dynamic woofers, bass chambers and acoustic filter networks, FATfreq was able to design the deepest bass ever recorded of over 20dB, concentrated below 200Hz with zero bleed. Not for the faint of heart.

NOAH MODULES: Customizable bass chamber technology that revolutionizes in-ear monitoring. Switch out your modules for personalized bass tonality and tuning while benefiting from the pressure relief valves which prevent ear pressure build-up. Experience personalized sound and ultimate comfort with Noah Modules. Built with BASS CANNON™.

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 the entire FATfreq IEM lineup.

Best I’ve heard yet.

I have a few TOTL IEMs including Noble Kubai Khan, the original 64 Audio U12t, Moondrop Variations, Thieaudio Monarch Mark 2 & Prestige LTD, 7th Acoustic Supernova, Dunu SA6 Mark 2, and without doubt the Grand Maestros are the best I’ve heard yet by a significant margin. FatFreq’s noted and notable bass is there, and a lot of it IF the music contains a lot of it, deep with amazing thump & definition, but the mids are no slouch with great clarity & presence, and treble plays its part magnificently, lending detail and air to the mix. The one issue I have with the GMs is comfort, or lack of it in my ears: the deep insertion design of the nozzles coupled with the above average weight of the IEMs means listening sessions of more than 60 or 90 minutes are not in the cards for me: tho short they are well well worth it and very rewarding. As ever your mileage may vary but the GMs are a truly special set.
