With the balanced pads then treble is not issue, as it's smooth. What is a challenge, is source material, where treble already is forward.I'm really tempted to buy a pair of these but I keep going back to the posts I've read on the treble. Some people call it fatiguing.
The build quality sounds great and I love the looks. The price isn't outrageous.
To give a examples. Studio albums from Five finger death punch are perfect - they are very balanced, great imaging soundstages and so on. Try listening to "house of the rising sun“
Skillet with the song monster - really not good. Almost completely opposite.
Katie Melua's first two albums kinda "Sssssh"
The last two, number 8 I think one is called are just perfect.
