Well I don't need anything portable because I'm pretty satisfied with my IEM's for portable use, these would be meant for desktop use with my home computer. I think comfort would be something that I would take into account too, for longer listening periods. I think if I buy the K121s the big benefit to me is that I can get them locally and return them if they aren't to my liking. Thanks for your help!
