Wireless Earbuds Product Review

Retest reading · GoodCase editors

What the creator aimed for

The creator wanted a phone-style talking-head ad for wireless earbuds: a young creator opens the case, gives two lines of recommendation, cuts to a work-and-walk montage, and ends on a product hero shot with one line of on-screen text.

Actual input and models

A single text-only prompt with no reference images, the two lines written out verbatim, and no stated duration or aspect ratio. The case tags list Seedance 2.0 as the creator's model; their settings and attempts are unknown. We retested on MiniMax H3 Max 768p with the prompt unchanged.

Test conditions and runs

Tested on 2026-09-07 with MiniMax H3 Max at 768p (from the model name); the provider receipt confirmed the model. One generation (n=1), scored automatically by claude-sonnet-5 and gpt-5.6-sol. No human verdict.

What held up

Final score 83.9, with the judges at 83.3 and 84.5, a 1.2 gap, so they largely agree. The automatic transcript matches both scripted lines word for word, so by the transcript the spoken script came through intact in this run. No silent stretch in the audio.

What failed or can't be told

No failure reason is recorded. Neither the score nor the transcript shows whether lip sync held, whether the earbuds looked the same across shots, or whether the closing line of text rendered correctly.

Variables to try next

Add a product reference to lock the earbuds and case. State the duration and aspect ratio. Try the lines in Chinese and see whether the transcript still matches. Generate more than once.
