I recently bought a Nintendo Switch and found that it doesn't use Bluetooth for an audio headset, only to connect Joy-Cons. I travel a lot for work and would like to use Bluetooth headphones to play with my Switch. This device came in a pinch! Following the instructions, I connected my headphones to the transmitter, plugged the transmitter into the Switch's headphone jack, and voila! Now I can play my games on the plane or anywhere without a wired headset. A NOTICE. Make sure you understand how to switch between transmit and receive modes. In my situation it is set to "Transfer Mode". There is a video on YouTube that explains this feature.
