Which should you buy?
What decides this is not the score, it is the display. Meta Adventurer Plug-in Case shows nothing and answers through the speakers, while RayNeo iO shows information on the lens. Reading is far faster than listening, but you pay for it in battery, price and discretion.
Meta Adventurer Plug-in Case wins the overall score by 0.9 points, but that score averages six criteria and you will only use some of them.
Battery is not close: RayNeo iO lasts 48 hours against 8 h for the Meta Adventurer Plug-in Case. The reason is the camera: recording is what drains the cell.
Meta Adventurer Plug-in Case has a camera and RayNeo iO does not. If you want to capture without reaching for your phone, the comparison ends there.
Both have manufacturer-confirmed language support.
On price, Meta Adventurer Plug-in Case is 250 $ cheaper.
Watch the warranty: RayNeo iO offers 1 year and Meta Adventurer Plug-in Case offers 2 years.
