I struggle with this, perhaps it was insertion depth but that unconventional iem shape should never have been greenlit Average bass, thin midrange, unbearably sibilant treble

Bright and full sound, very detailed, sparkly, airy, tons of treble extenstion... but it gets fatiguing with the stock filters. Blue filter has the best balance but still doesn't scale too well. 300 mesh filter goes hard tho - check modded ranking at bottom.

An interesting sort of Science Project IEM. FatFreq tried to extract as much Sub-bass power and texture while making an airy, detailed planar that isn't fatiguing. They succeeded, and with the Super Stage NOAH modules, this is the most open and wide sounding single Planar I've ever heard. Wish it was cheaper and didn't come with the Ares S II cable.
