Well its more for music, gaming is just a secondary use.
So the grado is a domestic kind of headfone?
I took a look on the tad400 theyre portableand play also well on potables but they not are not what i looking for,
heres a list of demands for the headphones listed from important to less important):
Music,good bass(i want them to shake my ears but not xb-500style) comftreble cans,portabillity and at last gaming
plenty of bass
but not too much
good for gaming
at a $100.
I think you should really consider the
Audio Technica ATH M50, which I've
seen recently on Amazon for as low
as $107. (down from $150). Not true
portables but can be used as such,
plenty of bass, comfortable, well made,
and in fact they fold for traveling.
It's another highly praised headphone
as is the SR80i
but it's geared more towards what you
are looking for.
If others come to mind I'll post them here
