I'm thinking about buying the AKG Q701s, the Fiio e7/e9, and one other pair of headphones for portability. Do you think this is a good setup? Also, will my speakers benefit from the Fiio e7/e9s? They are plugged in so I don't know. What about the ATH-M50? the Sony MDR-XB500? Which one would you recommend? So basically my questions are:
AKG Q701 vs Beyer Dynamics DT 770/880/990
AKG Q701 vs K701 vs K 702
Fiio e7 and e9?
Will my speakers (plugged in)benefit from the fiio e9?
For portability use with my ipod and fiio e7, ATH M50 vs Sony MDR XB500? <Keep in mind for portability wise, looks matter>
