You know those fancy Bluetooth earbuds you love using so much? Surprise: they won’t work with your Nintendo Switch, or the seatback TV screen on a plane. But for just $16 (with promo code Q7BINWU2), you can plug this Bluetooth dongle into any headphone jack, and connect to it with your favorite wireless headphones for wireless listening.
It also works as a Bluetooth receiver, so you can plug it into an old stereo system or car, and broadcast music from your phone over Bluetooth to speakers that otherwise wouldn’t be compatible.
