I have a couple of different headphones and I find that, for mixing, the DT-770 is a bit
too heavy on the low end for me. But if you know your headphones really well and you
listen to your music through them you might want to stick to them.
I use a pair
of Fischer Audio FA-003 headphones for mixing duties. I do most of my mixing on my
near-field monitors but for things like checking the low end and cleaning up tracks the
Fischers are indispensable for me.
What is currently feeding your headphones?
My experience is that a dedicated headphone amplifier can make a positive audible
difference over most
integrated headphone outputs. For example the low end sounds
much more solid on my DT-770 with a separate headphone amplifier instead of using just the
headphone output of my audio interface. It's not just speakers that like a bit of power
Try listening to the same song(s) from different headphone sources and I
think you'll hear differences.
