Merchant accuracy notes (please verify before publishing)

• ANC conflict: Specs list “Active Noise-Cancellation: No,” but feature bullets say “Active Noice Cancelling.” Unless you can confirm hybrid/ENC/ANC, list without ANC and call it noise-isolating only.

• Bluetooth version conflict: Table shows “Bluetooth Version: Other,” but product name/specs state Bluetooth 5.4—publish as BT 5.4.

• Battery phrasing: “~4.5 hours (used with charger)” likely means ~4.5 hrs per earbud charge with additional charges from the case. If you have total runtime (buds + case), include it.

• Licensing/IP: “TRANSFORMERS” may be a licensed mark—confirm brand authorization for marketplace compliance.
