...So I'm shopping for a new set of wireless headphones, and considering what I'd get for the money, how much I need, etc.
Whereupon I find this Amazon Q&A:
Question: How well do these block out my girlfriend talking?
Answer: Her voice is already inside your head. Even if you break up with her, she will slowly seize every neuron, thought, memory, and a pair of headphones will not stop the complete take over of your soul. Say goodbye to your sense of self.
