^^vs he500 from memory:
Pandora 6 =
Similar midrange balance
Smoother treble but may be as bright?
More bass with better punch but more reverb
Honestly the are the closest hp's in balance to the 6 but if I had to choose only one headphone it would prob be the 6 because it's more natural and dynamic. I can't remember things like imaging etc but I will have an he500 again soon and I am thinking of letting the he6 go to get the pandora but I don't know yet.
I know I am late but the mids are just as forward in the upper mids and a little less in the lower mids. Overall this headphone beats my crack/speedball n hd650 combo straight from my iMac out in a lot of way namely clarity. It's not as deep in soundstage though.
No I have no idea what to go with haha, hoping one destroys the other - oh well
Might have to demo one
