Manta’s argument is that a flat mask presses your eyelids. Contoured cups are the public design.
Sound versions add headphones; do not mix those specs with the base mask. We will not invent a “100% blackout” measurement.

Manta Sleep Mask
Contoured, often weighted eye cups. Manta publishes mask versions (Sound, Pro) on mantasleep.com.
Editors’ shortlist — published design (no darkness score). Official contoured-cup design still sold. We do not invent a lux-blocked rating.
Observed USD range $35–$89
Base Manta masks often list near $35–$49; Sound/Pro versions are higher. Confirm the version. Source: Manta Sleep. Desk research dated 2026-08-23. Confirm before you buy.
