[Kenneth Tanaka](https://www.youtube.com/channel/UC7QwWqU_ZcWVko-SZvgcdMg) has provided impressive latency test videos, and measured the time differences between the animation and the sound. In [his video](https://www.youtube.com/watch?v=I2aUhpz9rxI&t=225s), Xiaomi Redmi Airdots S headphones, connected directly to an Nintendo Switch over Bluetooth, provided latency of 300ms and 267ms, and the gaming mode reduced it to 134ms. Moondrop Aria headphones, connected to a headphone port on the Switch, provided -50ms of latency. From the results, we can expect Airdots S to introduce latency of 184ms in Gaming mode, and 284ms in Normal mode, compared to the wired headphones.
I’ve tested a lot of headphones myself with a TaoTronics TT-BA09 Pro transmitter, and you can see [the results](https://docs.google.com/spreadsheets/d/1XFW9iwd-9IY9uzFZ0GnWiWtLnA-UCJk6F5xMu9qc4OQ/) here. The values show how much latency the headphones and the transmitter will introduce when you plug the transmitter to the headphone port. The transmitter supports SBC/aptX/aptX LL, but the Switch only supports SBC. When you pick the Airdots S from the list, you get 318ms in Normal mode, and 128ms in Gaming mode. If you compare the numbers to Kenneth’s, you can estimate that the headphones on my list will have 36ms higher latency on the Switch. I’ve done the math for you, so you can check the value in green cells for the latency on the Switch.
**TL;DR**: I decided to share [my latency test results](https://docs.google.com/spreadsheets/d/1XFW9iwd-9IY9uzFZ0GnWiWtLnA-UCJk6F5xMu9qc4OQ/). They will help you estimate the latency when you connect the Bluetooth headphones to an Nintendo Switch. You can also estimate the latency when you add a Bluetooth transmitter to it.
