Big fan of Beyerdynamics. I am going to take classes soon that have over 100 hours of online lecture/podcast material per class for the next 3 years and would like to know which you would use to couple a fiio e17 to listen to these lectures(or maybe just through a laptop port sometimes). Noise isolation is not a must.

I'll take other recommendations too, but I'd like to stick to Beyer's because I have a freeggin huge head and it's honestly the only set of cans I've listened to for more than 5 hours and not notice they were on my head. Comfort is a huge factor for me. I currently run the T90 through a bottlehead. Have an e17 and Aune T1 lying around. Also, if listening to a youtube quality voice makes one of these headphones no different than a 50 dollar one, can I get some recommendations as well? Because if so, getting a 200 headphone just to listen to lectures while owning a t90 at home would be retarted.
