Yeah, either i listen to it completely flat or with a slight bass bump of 1-2 db and a 1-2 db treble boost.
But 1-2 db is pretty small.
When i first got them... I only listened to them flat.
But maybe after burning them in the sound changed? i don't really know for sure.
Maybe my ears simply got used to the sound. So then i wanted a little bit more bass... lololol
Only the TFZ #3 i NEVER EVER add bass to...
Usually i only add some treble. starting from 2k and up i add 3-4 db roughly.
But the TFZ #3 are MEGA bass cannons in my opinion.
The extra treble is to make them sound more balanced. hahaha
Welcome to the basshead club. I think you should check out the KZ ZS7 since you like bass so much.
