ขั้นตอน
- 1
Use a low-latency mode
Many earbuds have a "game mode" or low-latency mode in their app. It trades some stability for less delay.
- 2
Use a dedicated wireless dongle
Gaming headsets with their own USB receiver use a different, much faster connection than Bluetooth.
- 3
Go wired for gaming
A wired connection has effectively no added delay.
- 4
Adjust A/V sync for video
Many video players and TVs have an audio delay or lip-sync setting. Video apps on phones and computers usually compensate automatically.
- 5
Keep it close and clear
Interference causes retransmissions and larger buffers. Stay close to the device and away from routers.

- Using the headset's microphone at the same time switches it to a call mode that sounds worse and can change the delay.
