I picked up an AudioQuest DragonFly Red to use with my iPhone, iPad and MacBook Air. I already have some Massdrop Sennheiser 6XX headphones that I'm using with my Cavalli Tube Hybrid in my den audio setup. What are some options that I can take on the road, around the house, etc. to use with my devices that will work well with the DragonFly? I want something over the ears that's in between in ears/ear buds and the 6XXs. Sound quality and comfort are most important and I'm looking to stay in the $200ish and below range.

Are the Sony MDRV6s a bad choice? They are well below my budget but are studio headphones OK for casual listening?

Thanks for any advice.
