My current fave audio transmitter for my Switch is this Audio Stick from @skullnco ! I'm already using it for more than a month and I just love it 🥰
I got the limited edition EVA color. They also have the standard black color if the purple and green combo isn't to your liking.
What I love about this is that it's compatible with almost any case for your Switch! I used to have a GuliKit Route Air, which I also truly loved, but I couldn't use it when I have the case on my Switch Lite. With Skull & Co's Audio Stick, I won't have to take off the case anymore.
Basically, you attach them to the purple audio stick if you'll be using it for your Switch that has no case. The spacers come in three sizes: for Switch, Switch Lite, and the flat one for any other devices.
