My sr 325is sounds really thin with a smaller soundstage on an IPHONE 4s.
It's not like anyone listens to GRADOs at max volume (These headphones are loud enough  IMHO even plugged in directly) But I did put it at MAX volume to test out if it distorted on a smaller device...
 
And it did, but it was only with certain songs (The same songs that distort on my HD 558s)
 
Again, no one really listens at this level, as i'm sure you will go death, but I wanted to know if these are common signs of being underpowered or is it that my headphones are damaged?
 
And in general, I mean the distortion sounds.
 
When I first got the 325is out of the box they hit maximum volume with ZERO distortion... So why are they distorting a little bit now at maximum volumes?
 
 
I don't understand, And my HD 558s also show distortion at max volumes but this is a 50ohm headphone. (The aTH -m50 Absolutely no distortion)

Did they "hit maximum volume with ZERO distortion" with your iPhone 4s--or some other device?
 
Also be aware that being able to achieve high volume levels does not necessarily tell you that a can is adequately powered.  For example the Pro 750 will get very loud with an unamped iPhone, but will also lose all its bass.
 
Grado's, on the other hand, are usually easy to drive

It hits max volume with no distortion.
 
 
 
But only on classical music/orchestra or pink floyd
 
It has distortion on bass heavy tracks like skrillex or aviici

You didn't answer the question in my first sentence of my last post.
 
Have you tried the can connected to different powering devices--perhaps playing some of the same files?

I just grabbed my Grado 325i's and my Wife's iPhone 4s and listened to a small selection of music at full volume and though the Grado didn't sound that great being driven by the iphone, there was zero distortion and the music was clean. I was listening to Usher, lady gaga, and some other pop and hip hop type stuff which includes a good amount of bass. (Wife's music by the way)
 
I believe the Grados can be ran off phones but they come alive when driven by a proper amp.

Nevermind, all the distortion and thin-ness is now gone.  
 
 
I was just used to the m50 sound signature wich sounds like complete crap to me now lol
 
 
It's really incredible how the human ears get used to a sound
