Alright, I'll plan to bring my own headphones.
Last couple questions:
1. Is there a procedure for bringing our own music to demo gear with if we don't own a DAP? I'd rather use music I'm familiar with and enjoy. I've got a playlist on Google Play and I'm planning to load it onto a flash drive as well in case Internet isn't available, not sure if there's anything else I can do to make it low hassle short of forcing myself to listen to Hotel California on repeat.
2. Generally, how much time do we have to demo a single setup before it becomes a problem for other meet attendees? I don't want to be that guy, so I'm going to try to consolidate my demo playlist as much as possible and arrive early.
