I am looking for an ultra portable headphone amp to use between my iphone and my headphones, currently PX200-II and HD25-1 II. I understand i will need to get a line out adapter. 
 
Obviously sound quality is key but size and price are not far behind, in that order. I wouldn't want to go much larger then an ibasso T3. 
 
I can spend up to $200 shipped, though i'd prefer to keep it around $150 if possible. 
Is there an amp out there that matches my criteria?
 
Thank you for your help.
And if your answer is that i shouldn't bother amping either of these HPs I thank you for that advice also. 
 
Also if anyone happens to be selling an amp that matches i'd be interested to hear about it.

The T3 is a superb choice for your application.  Tiny size, 4 gain settings, excellent sound.   If you prefer a digital volume control, it would be the T3D.
