I would buy a Lightning to 3.5mm MALE cable if that were an option. Good headphones often have a 3.5mm port rather than a permanently attached cable which can be a point of failure.
I would NOT buy a Lightning-only set of headphones ever because it's not a standard port and only Apple uses it (and only on their iDevices). Adapters and dongles are not really acceptable for me (even ones better-made than the plastic junk shown here), and as far as Bluetooth audio has come it still isn't good enough yet.
