Test that setup before hand to make sure those headphones work as you remembered them too. It would suck to go through that again and come out empty handed. Also check to see if when the screen locks that it continues to record until you press stop. She will probably be about 5ft away from you so test for clarity at that range.
So many people are tied to their phones now days that it wouldn't look out of the ordinary to be holding it w/o heaphones and not using it. Just don't let her see the screen being active of course.
The guys on the board have a lot of good points that you could bring to their attention. Keep us updated and good luck.
Already tested it last night with my roommate. Crystal clear, even when the screen is locked.
Here's a general question about the addendum regardless of how it relates to the lease. The addendum states that I can be evicted for being a "habitual complainer" or by causing "discontent, unrest, dissatisfaction, or disturbance among other residents."
That sounds strangely like blackmail to me.
