This Nintendo Switch Bluetooth Adapter works great with Steelseries Arctis 3 Bluetooth Headset. I was initially concerned that it isn't aptx LL, but even without it, there are no lags at all. I use this Bluetooth adapter to play Fortnite without a bunch of crappy cables due to Nintendo's poor planning. The small microphone seems to work well when hand-held. However, when trying to play on a docking station, the microphone is usually too far away for others to hear. So I hope that future models will allow my Arctis 3 bluetooth headset or any other bluetooth gaming headset to work with both speakers and microphone! I'm only giving it 4 stars because you still can't use the microphone built into the headset. If you understand that, then 5 stars are guaranteed.
