Latency with TV (lip sync)

Where measured or discussed, latency is portrayed as very low and lip-sync problems are generally not reported, helping the Wireless II work well for TV and movies.

TV sync performance is a strength. Reviews that tested video sources through HDMI ARC reported little to no lip-sync trouble.

Lip-sync performance is usually reported as solid over HDMI, and several reviewers call out low latency for gaming/video; wireless TV-to-bar modes may be more environment-dependent.

Latency is generally well controlled (including reports of very low passthrough lag), though some setups can see more delay on certain formats over optical or wireless connections.

One reviewer measured Bluetooth latency at about 50 ms and described it as about as good as it gets in testing, suggesting strong sync performance.

Using HDMI eARC is described as quicker and less delayed than Bluetooth for TV playback; no major lip-sync complaints surface.

Reviewers note low latency for typical phone video watching, though it is not positioned as a primary TV speaker.

One review specifically highlights auto AV sync to keep sound matched to on-screen action.

Video sync appears solid based on limited evidence. One reviewer specifically said audio and video stayed well aligned when watching clips.

Latency is typically acceptable for casual video; the AUX input is mentioned as the better option when you need lower-latency playback.

When used for video on phones, laptops, or TVs over Bluetooth, reviewers generally report no meaningful lip-sync issues for casual viewing.

At least one reviewer notes audio sync controls are available (via app) to correct lip-sync delays when needed.

Wired playback is effectively lag-free, while Bluetooth latency is usually minor enough for casual video and gaming, though one review still noticed slight sync delay on close inspection.

For video use, reviewers generally report low perceived latency over Bluetooth, and some use the speaker as a simple TV/audio source via AUX when needed.

One review claims latency is not an issue for watching videos, suggesting acceptable sync performance for casual A/V use.

Latency is usually fine for TV use, and at least one review notes Game mode can reduce processing and help if latency is noticed (especially when using optical).

Bluetooth 5.3 helps keep video delay low; minor latency was noted by at least one reviewer but not usually a deal-breaker.

Lip sync is generally solid over HDMI ARC/eARC, and some reviews mention adjustable delay controls. Results still depend on TV audio settings and passthrough behavior.

Lip-sync is generally not flagged as a major problem, but one review reports brief half-second audio skips with UHD Blu-ray content, suggesting occasional source/format sensitivity.

One review notes roughly a one-second delay after unpausing, but the app also provides lip-sync correction.

Latency feedback is mixed: several reviewers note noticeable Bluetooth lag and no dedicated low-latency gaming mode, while others say it is fine for casual video; USB-C can reduce lag but may not eliminate it in every app.
