Slim & Stylish: The Catalyst Waterproof Case for iPhone X

As expensive as the iPhone X is, you're going to want to protect it from scratches, drops, water, dust, and more. I've used Catalyst cases before, so I tried the Waterproof Case for iPhone X ($89.99) with my daughter's iPhone X. As protective as the Catalyst case is, it's still surprisingly slim. The iPhone X is water resistant, but this case makes it waterproof to 10 meters.

The slim design ensures the case is compatible with Qi-charging. There's even an included lanyard, which is another way to protect your phone, as you're less likely to drop it in the first place. My only concerns are that the rubber flap can be tricky to keep in place and it's only sold in one color—black with clear back and front.

If you don't need the waterproofing feature, Catalyst offers impact-protection cases, in more color choices and at less than half the price. Speaking of saving money, if you have expensive Apple AirPods, they can be easy to lose; so I'd recommend Catalyst's Waterproof Case for AirPods, especially the Glow-In-The-Dark option. For under $30, you can clip your AirPods to your backpack or purse and even find them in the dark.


  • Surprisingly slim
  • Robust protection
  • Sealed ports
  • Compatible with Qi-charging
  • Optional lanyard


  • Rubber flap can be tricky to keep in place
