Hes looking for a pair of comfortable headphones , with high sound quality. Preferably something he can use on a plane but that's a secondary use.
Comfort is huge for him , he had a pair of PSB m4u2s but found them to be too uncomfortable(and actually lost them on the plane, yikes ). Those were noise cancelling but he's thinking of moving away from that for sound quality.
He woul prefer a pair with a detachable cord, and one that could be used with out an amp. However he has a portable e11 amp and wouldn't mind a pair that would be improved by an amp.
Any suggestions would be great! Budget is flexible(if paying a bit more would be a huge improvement) and IEMs could be an option however he's concerned about comfort with those..... I'm kind of new to the headphone world my self so not really sure his best option!
Thanks a lot !
