Before Seidio’s waterproof and dustproof seals can meet or exceed a variety of industry standards, they first have to satisfy the exceedingly high bar put in place by Seidio engineers. All of our phone case tolerances are meticulously measured and precision-cut to provide a fit like no others.

It seems because water is an essential for life, it’s also essential we protect against it. Too often we spend time in and around water and it frequently foils our phones and electronics. The same can also be said for dust and dirt, and although they’re not essential to life, life just never happens without them, either. Don’t let the elements seal your phone’s fate. Protect it with Seidio.


Of the many benefits people expect from their smartphone cases, first and foremost is some kind of protection. After all, the realities of life often include smartphones being accidentally bumped, hit and dropped–no matter how careful we are in handling them.

What makes Seidio’s cases so astonishing is the level of protection our products provide, while still remaining slim, lightweight and non-clunky. Many of our cases meet a variety of industry drop protection standards. And all of them are engineered for life.


Whether you’re an active outdoors person or not, there will always be moments when you’re outside of your home or car and Mother Nature comes calling. That’s why Seidio designs and engineers cases for outdoor lovers as well as for those might rather stay inside.

From the slimmest protection available to tough, rugged outdoors defense systems, Seidio cases cover a wide range of safeguarding options in a broad collection of styles. So whether your fair-weather or up for anything, Seidio cases have got you covered.


We are referring, of course, to families with children. Whether it’s toddlers or teens, or both, it seems no group of humans is more likely to be involved with smartphone accidents. Who would have ever imagined we’d have to protect our devices from baby bites and drool? Two-year old temper tantrums? And absent-minded young adults?

Well, we at Seidio would. And we did. That’s why we’ve designed products that fit parents’ lifestyles as well as their lives; lives that include the unpredictable actions of children.

    The Obex case is amazing, I purchased my first one almost 3 years ago and have been using than ever since. They’re sturdy and strong with solid drop protection and a comfortable feel. The sound is almost completely unaffected thanks to the membrains they use. I have taken my phone swimming with me and even taken a video of myself cliff diving from about 20 feet up all without issue or damage to the phone or the case. The Screen protector is also amazing, it feels very nice on the fingers and I have had no issues with using the screen, some screen protectors I’ve used have caused issues when typing. The power and volume rocker button covers are low profile enough that you don’t accidentally press then when you take the phone out of your pocket but high enough to be easily findable without looking. Now to the downsides. The sunken design of the windows for the front indicator lights, cameras, flash and speakers make it difficult to clean which will result in blury pictures after a while. They can be cleaned but I found that I generally needed a Qtip to really clean them properly. The screen has a habbit of picking up small bits of dust which don’t just rub right off. The biggest issue and the reason I’ve had to replace my Obex case twice is the rubber hinge construction. Due to the force required to open the clips for the power port the rubber used for the hinge will fail and rip over time. Also having headphones in with the case in your pocket caused a lot of wear to the hinge on the headphone cover. In my first case the headphone cover ripped right off with a below normal amount of use and with my 2nd and current cases the lower door hinge has failed and ripped off. The case still appears to function and be water tight but especially with the headphone cover it is easy to loose the detached cover. In conclusion, this is a great case with a lifetime of about 18 months.

    This is by far the best case for an S4. Did lots of research (almost picked otterbox) before deciding on my first Seidio case.

    The case is very smooth, so it is easy to remove from pockets and doesnt get stuck like other cases. No feedback from calls or noticable sound lose. Something many other cases fail with like the otterbox defender. The screen does not scuff, and has remained very smooth for the time ive had mine.

    Bought 2 1/2 years ago and still using it. It still protects the phone well, however like other reviews, the first thing to fail is the rubber hinges for the charge and phone plug. This is to be expected for what its been through.

    My case has been dropped from a motorcycle twice, went through water, mudholes 4x4ing, sits in coveralls everyday getting pushed squished you name it. Welding, grinding, It has hit the concrete at every angle from over 7ft up numerous times. No screen crack at all, case has dents in the plastic, but does not chip or crack in any way.

    Like i said best case by far. Will buy another one if i dont upgrade my phone soon!
    Thankyou Seidio

    I had the Obex for my Galaxy S4. Best case ever, in my opinion: it provided great protection against water, dust, and drops (thanks to it, my S4 survived a 3 meters drop without a scratch). If you’re looking for a 360° protection for your phone, the Obex is the best you can have.
    (Now I don’t use it anymore, but only because I’ve bought an S7, and the Obex production seems to have been discontinued. Sorry to see that, personally I’ve never seen a water-proof heavy-duty case with so much good reviews on sites like amazon, etc. If they start producing the Obex again for newer models, it will be my case again for sure!!!)

    Fantastic case. I used mine until my S4 died. I replaced it with an S7 and was really disappointed that the OBEX line had been discontinued. Was forced to switch to Lifeproof and they dont even compare to the quality of my old OBEX. Come on Seidio, bring it back! I’d buy one in a heartbeat.
