I am looking for a pair of decent headphones within the budget of around $200 with a portable headphone amplifier. I would be using it to commute daily and also for part of my studies in audio engineering and recording studio . I listen to mostly punk rock, punk pop and rock and also I do not blast my headphones at extremely loud volumes. I've also been to the local audio shop to test different brands of headphones before settling on the few selected models as shown below.
Beyerdynamic DT 770(250 Ohm)
Beyerdynamic DT 990(250 Ohm)
The 990 sounded much more detailed as compared to the 770 but being an open can headphones, I am a little afraid that the sound leakage from these headphones might disturb the others around me in the quieter environment. The COP seems to be an okay choice between the two though I feel its more catered towards the ones who enjoyed bass.
For the portable headphone amp, I would be getting the Fiio E11 if I am getting the DTs but I am wondering if its enough to drive both headphones to their fullest potential. Any other recommendations for other headphones paired with the amps are welcomed too ! I would be getting my gear from Amazon at the end of the month
