I'm sorry I'm a complete rookie to this so here Is my rookie question. Just bought sennheiser over ear momentums. With iPhone 4S as a source are any of these port amps better suited to my setup and why. . I would upgrade to an iPod if that would help SQ. . ( i know Probably a different forum)...

All kinds honestly. From country to Metallica not so much rap or classical though.

First I apologize for the rookie post. I read the forum extensively and only got more confused. Here is my situation.....I have a fly in fly out camp job, about 2 hour flight each way, plus hour bus ride. In the evenings its quiet in my room to watch movies, listen to music on ipad/iphone 4s...
