Interesting review!  High volume listening = flatter frequency response.  At lower volumes our ears are unable to perceive low and high frequencies as well.  At higher volumes, the hairs in the basilar membrane will fire more frequently.  Just a thought. 

Damn! One more contender in sub 100 or should I say around 150? 

Seems that you are quite undecided about the sound. Why not listen to it again. This time, walk slowly.

@Onny Izwan what do you mean? 

I mean listen to it again. This time, focus on the music and how they sound to you. 

@Onny Izwan Still not 100% sure what you're trying to say here, my opinion on the TFZ 5 is pretty firm (so much that I've ordered a second pair).

I'm glad. Thanks for the review, dude

Dude the harakiri thing worked like a charm! What.
