Which should you buy?
Both belong to the same family, so here the scores are genuinely comparable.
RayNeo iO wins the overall score by 0.1 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 12 h for the Halliday G2. At that gap, one lasts the day and the other does not.
Both have manufacturer-confirmed language support.
RayNeo iO is 16 grams lighter, which you feel on your nose after eight hours.
On price, RayNeo iO is 100 $ cheaper.
