Mous vs OtterBox vs Spigen: Which Phone Case Survives a Real Drop Test?
When you’re carrying a $1,200 smartphone, a drop is not a minor inconvenience—it’s a potential repair bill. While almost every brand claims “military-grade drop protection,” we put the three leading options to a series of physical drops on concrete to find out which case actually keeps your glass intact.
Mous, OtterBox, and Spigen cases tested side-by-side for drop resistance, bulk, and design comfort.
The Quick Verdict: Which Case Wins?
Mous Limitless 5.0 wins the top pick. Its proprietary AiroShock padding absorbs impact energy far more effectively than Spigen’s plastic air-cushioning and offers a significantly slimmer profile than OtterBox’s bulky defender setup.

Detailed Product Breakdowns
AiroShock Technology: Microscopic air pockets dissipate shock from drop impacts without requiring thick rubber bumpers.
