Fiio did some magic with these FF3 buds, they call it "drum bass cavity" or "bass boosting flute design"... or whatever lol. Most IEMs have louder bass but they sound like when you hit a pillow. I own some expensive IEMs like the Variations and IER Z1R, they all have superior sub bass rumble, but I don't get the same punch like the FF3, it's so weighty and addictive. Maybe because of the open design, larger drivers or something... I've stopped buying IEMs recently, I am looking to buy more buds like the FF5 and DIY stuff
I only have the og VE Monk. Haven't listened to it for a few years so I couldn't accurately say (I'd have to dig through a bunch of boxes to find it). But I remember having some special moments on the Monk whereas the FF3 only gave me ok times. 🎧
