Get yourself a great headphone line! Cheap, sturdy, well built, clear transmission of signal, simply what I needed and wanted.
I've been using it in the home studio, in location recordings, in a barn my mates and I converted in a recording studio for 3 weeks, it never failed me and the length is good!
I personally hook this from the interface to my wireless in ear monitoring system: the emitter can be close to me (and away from the recording gear in case of RF interference) or I can just plug my headphones and have enough room to perform
