 So we actually don't use Bluetooth. It is a Bluetooth speaker, like if you just want to keep Bluetooth. But yeah, this is actually a proprietary wireless technology. It's called SKA. You can look it up. S-K-A-A. It's kind of you can think of it as a high performance competitor to Bluetooth in some ways. It's super low latency. So it's 19 milliseconds, which is, you know, less than your nervous system can detect. Wow.
