I previously owned the k550, lovely pair of cans and I just used to drive them from my e17 and needed nothing more... If your're not using a DAC+ amp setup you will see a bit difference in terms of clarity sound quality and most important the amazing soundstage of the k550's, but Id advise to...

lucky guy lol ^ as for me, my ears are just too damn picky, which means my wallet is the one usually paying the price :/

Quote: they were wayyy to harsh to listen to at the slightly above average volumes i listen to

bose ie2 are literally as good as stock earbuds that come with your pmp or cell phone, i have no idea why in the world people would by them for 100 bucks, and they still continue to do so :x

no problem, i just got my e10's as well and they sound great, very enjoyable listening any type of music on them especially acoustic, and smooth vocals, nice bass extension on them as well let me know what you think of them when you get em, and i suggest you play around with the earbuds a bit...

depending on where you are sitting in a concert, and what type of concert ;)

thanks, i couldn't have gotten a more straight forward response, exactly something i was looking for

just to save your time and money just read this review and see how much praise a sub 50 dollar headphone can get  http://anythingbutipod.com/2011/08/soundmagic-e10-review/ a very respectable reviwer in my opinion with little to no bias

i think youd be pleased with a fiio e7 and e9 combo

i drive my hd650's just fine through a fiio e10/e17, trust me you'll be pleased

lets see how well sennheiser does with this amp

are they really worth their quadruple digit price-tag?

there might have been a chance you could have gotten a fake pair of cx300's, imo their quality buds for the price you can get em now you can get soundmagic e10's for 35 bukks which are very highly rated

for me had to be klipsh s4

and not to forget the $40 price tag!!!! :)
