FATfreq x HBB Deuce

I have to knock it down a star, for the diabolical unboxing experience, whimsy cable and the lack of specs. Otherwise, the IEMs do excel in subbass rumble and midbass slam like no other (that I've tried). The mids are slightly recessed for my liking, and the treble extension is not ideal, but it's not intended to excel in every genre and that's okay. Cost-effectiveness is average.

Exceptional IEM

Best IEM's I've listened to! Rumbling sub-bass, powerful bass, clear mids and highs. Just perfect. But not all is great... The cable is practically impossible to wear because of the microphonics and the case is so small that you have to squish the IEM's and cable to fit, making me afraid of damaging the goods. Very, very poor unboxing experience for the price. But the sound of this IEM's are pure bliss and make all the bad things small compared with there excellent performance.

Very good, I like. It very much. I don't need to use any eq and just right for me.
