It looks like it's a standard 2V source. It's got up to twice the output of the iPod.
I wish Dan posted FQ graph comparing 3.0 with the latest 3.2 revision.
How do the new Mad Dogs compare to the older Denon DX000 series and HE-400 in deep sub-bass frequencies below 50 Hz? Is it enough to satisfy a bass head?
How about soundstage, imaging, and instrument separation?
Pretty decent isolation, pretty durable, pretty big physically. I might consider them for flying (all commercial for me), but would likely choose my custom iem's instead for convenience and even better isolation. I'll let more experienced travelers weigh in as well. I travel a couple times a year give or take. Always the iems, likely never the Mad Dogs, just based on the physical size, weight, etc.
I assume you are talking fixed wing.
Given the conspicuous lack of noise insulation on most mil transports that would be a challenge even for an iem.
yeah fixed wing. KC-135R to be exact(CFM 56 engines). I've actually used some "IEMs" by a company called AirBuds that worked somewhat well in the jet, however I haven't found any fullsize headphones that would do a decent job of protecting my hearing from the outside engine noise
