Best portable headphones and DAC
The operative word is PORTABLE. I like my current set-up (which consists of an AQ red dragonfly and a folding pair of sennheiser headphones.) but I,m wondering if there is anything better out there. I also have a chord mojo but I,m not sure I would categorize that as portable. It mAy be fine for taking on a flights but it's too heavy for walks or bringing to a health club , IMO. I'm debating about upgrading the dragonfly to "cobalt". The reviews are mixed as to whether it's worth it if you already own the "red".
