Audio Mapping / Headphones

I'm going mad I know I am. Today I wanted to work on my Bluetooth headphones during an edit, and it's not uncommon for me to do so. However I turned them on to ensure I was connected, but Premiere was still playing out on my speakers. I went to my audio mapping, and it looks like my output should be coming to my headphones, but it's still going to the speakers. Here are some screen shot references. 

Headphones are WH-CH700N

Speakers are routed through my Blackmagic Playback.
