Hi! I got my hd560s like 2 weeks ago, upgraded from the razer barracuda x.

They did not blow me away, i did not notice a different at first. I did however find myself listening to music more and more, and i sang along more, and i danced more.

In my experience this is a sound you grow into, and you'll be extremely happy you did. But it's not as drastic a change as I expected, and you might expect it to be.

Btw: it doesn't need an amp. I run it through a Samsung dongle which has an amp but the 3.5 jack from my laptop does the job.
