Samsung Galaxy S3 Seidio OBEX Waterproof Combo

Product Description

Protecting your Samsung Galaxy S3 is not always easy, but Seidio’s OBEX utilizes advanced technology that not only safeguards your device against drops, but also keeps external elements like water, snow, mud, other liquids, dust, and sand from damaging your device. Includes OBEX Holster.

The materials and design of this case ensure that your Samsung Galaxy S3 is protected at the highest level possible. While the curvature provides a secure grip and absorbs shock if your device is dropped, the built-in screen protector promotes touch sensitivity and clarity. Waterproof membranes prevent external matter from entering the microphone and speakers while maintaining sound quality. OBEX will give you the ultimate protection anytime, anywhere.


  • Case exceeds IP68 rating
  • Critical points of entry are blocked by two-stages of protection
  • Anti-reflection glass protects camera lens
  • Waterproof membranes shield the microphones and speakers while maintaining sound quality

Drop Protection

  • Exceeds the MIL-STD-810G test, which evaluates the case from 4 feet drops at multiple angles
  • Internal structure is designed to protect your Samsung Galaxy S3 in the event that it is dropped or compressed
  • Combines Polycarbonate and Thermoplastic Polyurethane (TPU) materials
  • Raised edges on the case and the 4H hardness rated screen protector create a barrier from external elements

OBEX Holster

  • Spring clip lifts for easy access
  • Secure locking mechanism
  • Adjustable swivel belt clip with 7 rotating angles
  • Only fits Seidio OBEX Case

Star Star Star Star Star Fantastic case
User: Sam C, Nov 25, 2013
Pros: Great protection
Cons: It is a litlle on the big side, but it is a big phone.
Money well spent. I work construction and am outdoors a lot in all weather, rain, snow, dust, dirt, mud and so on. The case keeps it all out.

The case is a tough case. i was using the flashlight app on my phone and I dropped it off a boom lift, it fell 15 feet struck a roof, bounced and fell another 15 feet before hitting concrete. it bounced a few times after hitting the concrete. The whole time the flashlight app stayed on even after it came to rest. No damage to phone or the case.

The belt clip it strong as well and locks securely. I snag it from time to time and it holds up well. Coworkers with other brand of cases have had their clips break a few times but mine is still going strong.

The little dots on the between the phone and the screen protector that others were complaining about bothered me a lot at the start but they go away after a little while so it isnt really a issue except at the beginning.

To start i put the phone in wrong the first time and people couldnt hear me on calls because i pinched the membrane wrong at the microphone, but that was my fault and it just need to be taken out and put back in.

It is a little big but the phone while being thin is wide and tall. Considering it is a full protective case the size isnt that bad.

All in all if your looking for a rugged case and need the water and dust protection, then i would recommend this case for you.

Pros: Tough and waterproof
Cons: annoying prismatic dots on screen and slippery
Definately better than the otterbox however the sides and back dont have the rubberized coating like the front which is backwards if you ask me. This makes it slippery and hard to grip. those prismatic dots on the screen are very noticable and not neccessary as no other cover has them. with that being said it is a tough case and i would recommend over others i have tried GO GATORS

Pros: waterproof, dustproof, drop protection
Cons: back material, screen protector
I have been excited about this case coming out! I have bought many Seidio accessories for my HTC EVO in the past that were great. When I saw ShopAndroid had it on sale and a 60 day money back guarantee I was sold. Seidio only offers a 14 day return policy, if product is defective though they do offer a year warranty. When I opened the package I was presented with an Addendum to the Manual. It stated that if you saw little dots on your screen those were for greater touch sensitivity and to prevent "water marks", when the protector sticks to the screen. Well if you have a dark background you hardly notice the dots, theres about 20-25 dots on protector (maybe more, I dont remember). But if you had a lighter background on a wallpaper, game, app, etc. the dots would act like small prisms. It looked as if you had glitter on your screen, really distracting. Especially while watching a movie. I thought I would get used to it, but I couldnt get past the dots. I was quite disappointed. I did email Seidio and asked if this was an early iteration of the product or if they were going to this design. I was told they were going to send my email to the technical department and they just reiterated the same Addendum to the Manual that came with the product. So, not much insight, or questions answered. I saw this case licensed under PT cases and sold at Best Buy, when opened the package it said Seidio,and when I looked at that one in the store it had no dots on the screen protector.

The case added some bulk to the phone, and I realized it would, but the plastic material on back and sides of the case made the phone a little slippery when holding. It did help with putting in pocket etc. I do know there needs to be a compromise when designing these products. When I did the water test before putting the phone in the case (which is required and highly recommended) it worked perfectly. If you can get past the screen protector and dont mind the materials used, it would seems like a good waterproof, dust proof case. Just didnt work for me.
