Not so with the LifeProof cases, which claims to be the slimmest waterproof case for the iPhone, adding just a sixteenth of an inch in thickness.

A stolid case in black, pink, purple or white, it won’t win any aesthetics awards, but it is simple to use. Just squeeze the phone into the front piece of the case (it requires some force), then snap on the back. Make sure to run your thumbs all around the seal. Failure to do so is the main reason the cases leak, the company said.

Sound quality is unimpaired by the sealed cover — people I called were unaware I was talking to them through a waterproof fundas iphone china. I was able to type accurately through the clear screen cover; I just had to press a fraction more forcefully.

The case comes with a screw-in headphone attachment that lets you listen to your tablet android when submersed, provided you also have sealed earphones.

One of the better-thought-out features is a clip at the bottom that lets you recharge the phone without removing the cover.

The case is $80 from LifeProof, which also sells accessories like a bicycle mount and a belt clip.Estuches iphone Venta al por mayor

The company says the cases is waterproof, dust- and dirtproof, snow- and shockproof. But because LifeProof only warrants the case — not the phone inside — I didn’t have the guts to test it by leaving the thing underwater for an hour as the reviewer’s manual suggests.
