As compact as possible (without being too flimsy) with a 'robust' Bluetooth signal at close distances.
Good sound quality for portable h/phones (Sennheiser PX-100 MKII and B&W P3s are the 'benchmarks' inasmuch as the PX-100 MKIIs are the very lowest SQ I would consider but - preferably - closer to my P3s if that's reasonable to expect with wireless.) I would prefer the quality to be strongest in the mid-range and upper bass and voice.
Open backed preferred but not essential. On ear rather than 'over-the-ear'.
Reasonable battery life at moderate volumes. (Volume is allways moderate as I look after my hearing and even leave the volume limiter on to prevent accidental exposure to loud volumes.) I don't want to be charging it after every single use.
