The only wearable that will ever be acceptable is glasses on a leash. Basically light weight glasses that provide a user controllable altered reality extension, with close ear speakers (not in or on, just close). Connected by wire to in pocket hardware. Add a couple on rings to your fingers, first joint index and pointer, both hands and being able to locate those relative to the glasses.
There is the useful wearable technology, until then candy bar smart phones suffice, although the LG VR glass add on certainly does expand the use of smart phones to full entertainment device, chilling out, lying back, enjoy deep content immersion.
