I've never tried what you want the sound signature to sound like, but I've owned both. Klipsch image can be harsh on the ears and has somewhat dry bass. The superfi 4's bass is much richer, however, the mid-bass hump is located much further up the spectrum. Also keep in mind the range numbers. 20-15,000 Hz or 10-20,000 Hz. Here's the other thing, I don't trust those numbers. If UE makes CUSTOM headphones that only go to 16 KHz, then universal fit will probably be exaggerating. Maybe they can handle that tone, not necessarily safely though. I trust a worse numbers over better numbers
