Bluetooth-Sharing Headphones

The main feature of these $200 headphones (apart from having glowing rings that flash with the music you’re listening to) is to “share” what you’re listening to over Bluetooth. But you can only do this if the other person also has a pair of the same headphones. The manufacturer suggests (in their photos) that a lady wearing these might want to smile at a stranger on the subway and share her music with him, which leads me to suggest that they’ve never used public transit.
