The Avantree USB PC/PS4/Switch adapter works perfectly in docked mode. I got it Saturday & it just took a minute or 2 in order to initially figure out how to pair your headphones (definitely make sure to reset your headphones & put them in pair mode & then follow the instructions) to it but then after that it works like a charm.
The Nintendo Switch having no Bluetooth was a surprising choice for Nintendo. Fortunately, the GENKI Bluetooth adapter is a fantastic accessory for fans of the Nintendo Switch. It is straightforward to use and looks the part as well. It comes packaged in a box that looks like a Nintendo Switch game, which I thought was cool. It has the slimmest form factor out of all the Switch Bluetooth adapters currently in the market. It comes bundled with a USB-C to USB-A adapter that let you plug the Bluetooth adapter to the side USB-A ports when the Switch is docked. It is the only Bluetooth adapter for Nintendo Switch currently on the market that supports dual aptX Low.
