The headphones really don't require much power at all to get them going. Hence the reason many people buying these for portable use as they don't require an amp. They offer quite a bang in audio quality at real good price. I can say with real confidence that you'll hear good sound/music out of them.
As to whether or not you'll be able to experience the full sound spectrum of these headphones from the devices you mentioned...there's not a definite answer for this. I'll be honest here as it's definitely a yes or no kind of thing with subjectivity.
As I've mentioned elsewhere, not all devices are created equal. They'll either power them sufficiently or be inadequate in power.
Some personal experiences of mine with the portables I have:
-1st generation nano powered these headphones decently, but there was real lack in bass extension despite using EQ settings to help. It was like listening to Led Zep's "Kashmir" with 15 dollar ear buds.
-Samsung Galaxy S3 drove these without too much problem. Bass extension was good without EQ and it sounded a bit more full with good details. Got similar results with our 1st generation Ipad, but it introduced an audible white noise (hiss) in the background. The hiss was absent on our 3rd generation Ipad though!
-1st generation Iphone had real trouble driving these headphones. Certain high frequencies sounded muffled and came out like static. Bass was quite weak. Our 2nd generation Iphone didn't have this problem at all.
-My HTC 3D EVO had no trouble driving these headphones but it introduces quite a loud hiss in the background and distorts very easily at higher volumes.
As you can see, your mileage could vary some here.
I'm comparing these experiences with either my home theater receiver or the Cambridge Audio DacMagic Plus (DAC) on my desktop where both offer clean sound with very low noise/distortion. This is one of the few reasons why some folk out there like myself pick up a DAC/AMP to get out of these pitfalls in audio quality.
You can probably see why I'm a bit adamant in telling people to try other sources out before they judge their headphones. You can't completely judge a book by its cover, right? Hehe!
All in all, try auditioning them if you're able to. Considering the fact that these headphones have gotten super portable now with detachable cables makes for a pretty darn good buy.
