The latency factor
The latency of BT vs USB is significantly different. WiFi vs Ethernet makes less of a difference. The biggest win is to use a wired headset. But I also think, where possible, using a wired connection also makes sense. Everything adds up.
| Connection | Typical Latency Min (ms) | Typical Latency Max (ms) |
|---|---|---|
| Bluetooth | 50 | 200 |
| USB | 1 | 40 |
| Ethernet | 0.2 | 1 |
| WiFi | 3 | 20 |
