I am okay with open cans.
Just standard sound card from my computer no extra equipment.
I generally like more bass however I now listen to anything from Dubstep to singer/songwriter acoustic music so as long as they are decent quality I will be fine. I listen to Spotify all day and am not a audiophile.
My main concern is the comfort and will be wearing them throughout my entire workday.
Thanks for the quick response!
At $150, no amp, bassy and not bassy (mid-centric) music genre's and need for great comfort you are almost certainly have to make some compromises.
Cans that might best meet your needs: Ultrasone HiFi 780, Shure SRH 840, Sony MDR 7510, KRK KNS 8400.
