Disappointed with another adapter that stopped working I was very skeptical. However, it automatically paired with my Sony XM4 headphones so quickly that they were ready to go. It even worked when docked! I can finally play in my free time and drown out my rowdy husband who I've been locked in with for over a year at home! THANKS FOR MAKING A WORKING PRODUCT. (Yes, it's capitalized because I'm SO excited to play Fortnite, Zelda, and all my games in pure bliss with headphones on.)
