GuliKit Route Air Bluetooth Adapter for Nintendo Switch/Switch Lite, PS4, PC - Dual Stream Wireless Audio Transmitter with aptX Low Latency | Compatible with AirPods, Bluetooth Speakers & Headphones (Not for AirPods Pro 2) | Perfect for Gaming, Movies & Music Streaming

I was currently using the older Guilikit Route+ Bluetooth adapter, which was an amazing little device that made it easy to use my Bluetooth headphones with not only my Nintendo Switch but with various other USB devices. It was great to not be tethered to my Switch with long wires while commuting on the train. It also had a pass-through port that allowed you to charge the Nintendo Switch while continuing to use the dongle. My one main dislike about it was that it stuck out from the bottom of the Switch if I decided to lean the switch on a table while I was playing, which put pressure on the USB connector on both the Switch and the Route+, which made it an easy breaking point.However, in comes the newer GuliKit Route Air, which significantly improves the previous dongle with very few cons. The new and slimmer form factor sits flush with the bottom of the Nintendo Switch and doesn't stick out as previously. The unit itself now has two A & B buttons, which allows you to sync two headsets with the dongle and 4 LED status lights (shows you how many devices you have connected and which Bluetooth protocol it's using.) It came in a nice plastic case with a USB C to USB A converter so you can connect it to your PC or any other USB capable device. It also has a plastic piece that the dongle sits on so it protects the USB C port whenever it's not plugged in, so it doesn't break by accident if you have it in a bag or case.Pairing a device is simple, you connect the dongle and hold either the A or B button for 4 seconds while your headset is in pairing mode. It then quickly connects and shows you if it's using SBC, aptX or aptX Low Latency. Unlike the Route +, whenever I would unplug the Route Air and plug it back it in, my headset would immediately reconnect. On the Route + it would sometimes take a few seconds or even need the headset to be re-synced before it would connect. I was using a pair of Shure SE215-BT2's and connected via the aptX LL protocol to the Route Air. The audio was great and I didn't notice any lag between the action in the game and the audio.Now depending on your needs, you might see this as a con. Unfortunately, due to it's slimmer profile, there is no USB pass-through to allow you to contentiously use your Bluetooth headset and charge the Nintendo Switch. If you have one of the newer Nintendo Switch units with improved battery life or a Nintendo Switch Lite, then this might not be that big of an issue for you. Also, depending on which case you're using with the Nintendo Switch, this unit might not fit 100%. I normally use a full size shell case with my Switch. As you can see with the picture, I managed to squeeze in the Nintendo Switch with the dongle plugged in but this isn't a preferred way to use it. This isn't the fault of the device, just have to make sure the case you're using has a notch big enough to fit in the wider size. You could use an adapter to extend it but then it defeats the purpose of the dongle being low profile.Overall, I'm very satisfied with the quality and ease of use with the GuliKit Route Air and probably won't use anything else unless GuliKit updates the Route Air with a USB Pass-through charging port. It's a shame the Nintendo Switch doesn't do Bluetooth natively but this is definitely a great solution to that problem.
