Dozens of case makers come to CES every year to show off their cases that protect your phone when this happens. Whoa. Whoa. Whoa, nice bounce. But how much can they handle? We challenged these case makers to a live drop test at CES. With ratings from 4.5 to 16 feet, these companies put their own iPhone Xs on the line to prove that Claim, and push their limits. From bumpers to covers to massive cases, we had it all. Cases that came with a screen or back protector in the box were allowed. Round 1, we dropped them from the height the case maker said. There's no way to keep every drop consistent so bare in mind, this is not a scientific test. Starting off the group was Caseology at four and a half feet. Three, two, one, drop. [MUSIC] Then, Vanessa got on the scisor lift and went to nine feet. [MUSIC] Then, 10 feet. [MUSIC] [MUSIC] 12'. [MUSIC] [MUSIC] And 16 ft our highest rating. Countdown let's get escited 16 ft guys. Three, two onedrop. [MUSIC] OWC didn't have a scratch on it, but some dead pixels on the screen meant they were out of the race. [MUSIC] Drop. Whoa, I'm getting really good at this. [MUSIC] Rhino shield pushed the boundaries beyond their claim and started off at 16 feet with it's bumper. [NOISE] ... Round Two. At this point, they have already proven the claim. So we're pushing them beyond their rating to find a winner. We dropped them from 16 feet. Three, two, one. Drop. Whoa. [SOUND] [MUSIC] [SOUND] [MUSIC] [SOUND] [MUSIC] [SOUND] [MUSIC] [SOUND] [MUSIC] [SOUND] And six made it through our final round at 20 feet. This is nerve wrecking Three, two, one, drop, aah! Whoa. [MUSIC] [MUSIC] [SOUND] [MUSIC] [SOUND] [MUSIC] And even at 20', some phones Still didn't break, so we went for a vertical drop from the same height. [MUSIC] [MUSIC] Rokform didn't crack, but had some visible scratches on the edge. [SOUND] Leaving us with three winners, Pelican, Supcase, and Zizo. Big round of applause for everyone here who participated and our winners, thank you very much. Catch the full show on CNET's YouTube channel, and let us know what you want us to test next.
