Review on 🎧 Switch Bluetooth Adapter Transmitter Receiver for Nintendo Switch, Bluetooth 5.0 USB-C, Built-in Digital Mic APTX, Low Latency, Voice Chat, for Bluetooth Speaker/Earbuds/Headphones/Airpods by Gerald Hill

The only transmitter whose mic works on the Fortnite Switch. I returned 2 others before finding this one. Updated March 31 - will be returned. The microphone works, but the sound starts to wheeze almost immediately after plugging it in. Tried it with different headphones. Back to the drawing board for finding a wireless bluetooth dongle for a switch with a working microphone.
