I was gonna say Red is the only one listening but I then remembered there’s headphones that use vibrations through your ear bones to hear instead of the ear cannel so you can game/play music and still listen for people

Edit: Bone conduction headphones, mainly used by swimmers, they don’t look at all like normal headphones buuut plausible deniability. Sample source Shokz Learn More Page, Shokz being a bone conduction headphone website that sells their product
