Why Bluetooth audio lags behind the video, and what fixes it

If voices in a video land a moment after the lips move, or a game's footsteps arrive late, you are hearing Bluetooth latency: the time it takes sound to be compressed, sent over the radio, buffered and decoded in the earbuds.

Where the delay comes from

Audio is encoded by a codec on the phone, split into packets and sent over Bluetooth. The earbuds keep a small buffer so that a dropped packet does not cause a gap, then decode and play it. True wireless earbuds add one more step: the signal often reaches one bud first and is relayed to the other.

Typical end-to-end delay

SituationRough latency
Wired headphonesalmost none
Bluetooth with SBC or AAC150 to 250 ms
Earbuds with a "game mode"60 to 120 ms
LE Audio with LC3 (when both ends support it)can be under 100 ms

Most people notice lip-sync errors above roughly 100 ms when sound comes late, which is why video apps try to compensate.

Why videos usually look fine but games do not

Streaming and video apps know the Bluetooth delay reported by the phone and hold the picture back to match. Games cannot wait, because they must react to your input immediately, so the delay becomes audible. That is also why a video app looks fine while a browser video or a social clip drifts.

Practical fixes

Turn on the earbuds' low-latency or game mode if the companion app has one. Keep the phone and earbuds close, without your body between them; interference makes the buds enlarge their buffer. Close other Bluetooth connections such as watches during gaming. For competitive games, a wired connection is still the only zero-delay option.

Choosing earbuds with this in mind

If video calls and casual games matter to you, look for a game mode in the specifications and for support for newer codecs. Budget models such as the soundcore life p2i show that low price and decent everyday performance can go together; check the manufacturer's spec sheet for the exact modes each model offers.
