Tom’s Guide instead says its US 55/65-inch lacks X-Balanced Speaker; that regional claim is not applied to the UK configuration. Unread 75-inch audio figures are not borrowed.

In the box–Table-top stand, voice remote, conventional remote, batteries, power cord and instructions. Release month is the named TechRadar fallback: its exact-model review gives 25 April 2022. Maker Hong Kong’s June release lists later planned July/September availability, which does not establish the earliest sale. UK spec fetches failed; Ireland exact-model specifications fill the bounded gap, with UK 75/85 specifications and mounting table retained. The review’s 77-inch price line conflicts with its own 75-inch size list and maker tables; no 77-inch configuration is added.
