Bluetooth Audio Delay
All Bluetooth audio is delayed because sound is compressed, buffered and sent in packets. Typical delays range from roughly 100 to 300 ms depending on codec and device. Measure yours with the audio latency test.
Why Bluetooth adds latency
The sender encodes audio into packets, the radio link adds buffering to survive interference, and the receiver decodes it. Each stage adds milliseconds. Video players usually compensate; games and music apps often cannot.
Codecs
SBC is universal; AAC is common on Apple devices; aptX Low Latency and newer LE Audio (LC3) can be faster when both devices support them. Your phone’s developer options (Android) show the active codec.
Game or low-latency modes
Many earbuds have a gaming mode in their app that shrinks buffers at the cost of more dropouts.
Reduce interference
Keep the device close and in line of sight; Wi-Fi on 2.4 GHz and USB 3 ports can interfere.
Use wired for music making
For playing instruments or rhythm games, use wired headphones. Our wired vs wireless guide compares both.
