A compact and high quality aftermarket product that allows you to stream audio from your Nintendo Switch via Bluetooth. There is no sound delay. Powered directly from the Switch console. I use Apple Airpods or Beats Studio Wireless 3.0. I have an official Nintendo portable stand with a charging port on the side, it connects to the USB-C port via the stand mount and still works as usual. I also connect it to my bluetooth receiver in the car. On the way, if I wait in my car for a short time, it works perfectly. Highly recommended if you are going wireless and need a more convenient mobile experience. You should definitely add it as one of the essential Switch accessories.
