Ok so here's my current setup.
I've been thinking of picking up a Sennheiser HD 650 to use at the computer and keep the k550 for outdoor use (I listen a lot of music on the go so it's well worth keeping them).
The reason for this is that I've been noticing that at a certain volume sounds start to kind off blend together and the bass starts to fade if I don't pump it up in the EQ.
But now I'm wondering, should I even get different cans or is it a better idea to upgrade the computer hardware first?
Any feedback/suggestion is greatly appreciated!
