While this limits its use on the normal Nintendo Switch, it's not a deal-breaker at all if you use a Nintendo Switch Lite.
However, that's also one of the downsides to this device - it's only meant for portable use and doesn't work at all if your system is docked.
The UGreen Bluetooth Adapter is meant for portable play and can hold eight hours of battery life off a two-hour charge.
It's a dual-channel device and supports Bluetooth 5.0, just like the other adapters on this list, and is easy to install and use. It instead makes use of the headphone jack at the top of your device. The UGreen Bluetooth Adapter is unique in that it's the only adapter that doesn't utilize the Switch's USB-C port when playing portable. Plus, it looks like a little Switch, and that's really cute. Overall, the ZIOCOM is a handy Bluetooth adapter and costs only $25. It can also be used while the Switch is in a protective case, which is a big deal for those who take their systems on the go. Despite having your own chat channel, the ZIOCOM Bluetooth Adapter does not have an internal mic, so you'll have to find another means of communication if you're planning on chatting during multiplayer games. The buttons on the left and right control of the device control the mic for players one and two, respectively. The ZIOCOM also supports dual-channel audio, which means both player one and player two can have their own private chat channel.
Once plugged in, a pair of LED lights turn on to indicate that your connection is active. There's no charging necessary either, as it is powered through the system itself.
Measuring in at just under two inches wide, a little bigger than the others on this list, but not by much. The ZICOM Bluetooth Adapter looks like a tiny Switch on its own and plugs right into the bottom of your Switch or through a USB passthrough if you're playing docked. Other than that, you're looking at the best Bluetooth adapter money can buy. So you'll have to expose your Switch to the elements to get this to attach properly during portable play. The only major downside is that it can't be used with most Switch protective cases.
The HomeSpot Bluetooth Transmitter comes in many colors to match your Joy-Con colorway, and at only $30, it's one of the best options for connecting your wireless headphones to your Switch.

Two LED lights correspond with each player and flash a different color to indicate whether a player is muted or if they haven't paired their headphones yet. The button on the left side of the device controls the first player's channel, and the button on the right controls the second player. It's a nice feature for those who take their local couch gaming online. The HomeSpot Bluetooth Transmitter is actually a dual-channel device, which means that two people can listen simultaneously. It's not just for portable use, though, and it can also be connected to the USB located on the Switch dock. The HomeSpot Bluetooth Transmitter for Nintendo Switch is a small and easy-to-use Bluetooth transmitter that connects to the bottom of the Switch.
