Speck Presidio Grip Case ($44)
One of the best all-around cases for any phone is a Speck case. That's because they're not too thick, not too thin, super strong and give you tons of extra grip so you'll never drop your phone.
The OnePlus 7 Pro is big, heavy, and extremely slippery. It could be the slipperiest phone we've ever used. As a result, we highly recommend a case like the Speck Presidio Grip. This case is military-grade and drop tested over 10ft, which means those curved glass edges will remain safe.
What makes Speck cases great is the unique dual-layer design. The inside is a soft impact-absorbing TPU material with extra thickness in the corners. The outside is a hard polycarbonate plastic for added durability. Then, there are slits in the plastic that lets that soft, textured, grippy TPU material squeeze through the back. This is what gives each Presidio Grip its signature look, but also makes it extremely easy to hold your phone without the fear of dropping it. They're tough, stylish, and more importantly -- work.
