Why the Yi Sports Action Camera Original Underwater Waterproof Case Matters

If you’re like me—someone who loves capturing life’s wildest moments, from snorkeling in turquoise lagoons to skiing down powdery slopes—you know how crucial it is to protect your action camera. I’ve had my fair share of close calls: a splash of saltwater on my lens, a sudden downpour mid-hike, or even a clumsy drop into a shallow river. These moments taught me one thing: a reliable waterproof case is not a luxury—it’s a necessity. That’s where the Yi Sports Action Camera Original Underwater Waterproof Case comes in. It’s not just another accessory; it’s your camera’s best friend when you’re pushing the limits.

I first discovered this case during a spontaneous trip to Bali, where I wanted to film underwater coral reefs without worrying about my Yi camera. After a few dives with a third-party case that leaked (and a very sad, water-damaged camera), I switched to the original Yi waterproof case. The difference was night and day. This review is my way of sharing what I’ve learned after months of testing it in real-world scenarios: from deep dives to dusty deserts. Whether you’re a weekend warrior or a seasoned adventurer, this case might just save your gear—and your memories.

Design and Build Quality: Built to Last

Materials and Durability

The Yi Sports Action Camera Original Underwater Waterproof Case is made from a combination of polycarbonate and rubber. The polycarbonate shell is tough—I’ve dropped it from waist height onto rocks, and it barely scratched. The rubberized edges and seals add a layer of shock absorption, which is great for clumsy folks like me. One thing I love is the matte finish. It doesn’t show fingerprints or smudges, which is a small win when you’re constantly handling the case with wet or sandy hands.

Compared to cheaper third-party cases, this one feels solid. There’s no flimsy plastic or creaky seams. The hinges are sturdy, and the locking mechanism clicks into place with a satisfying snap. I’ve used cases where the latch feels like it might break after a few uses, but this one still feels brand new after months of abuse.

Sealing Mechanism: How It Keeps Water Out

The case uses a dual-seal system. There’s a primary rubber O-ring around the main opening and a secondary silicone gasket on the lens port. Both seals are replaceable, which is a big plus. I once accidentally nicked the O-ring with my fingernail (rookie mistake), but Yi sells replacement kits, so I was back in business within minutes.

Pro tip: Always inspect the seals before every dive. A single grain of sand or hair can compromise the waterproofing. I learned this the hard way when I got a tiny leak during a shallow dive—luckily, my camera survived, but it taught me to be meticulous.

Size and Portability

The case adds about 1.5 inches of bulk to the camera, which is standard for most waterproof housings. It’s not the slimmest, but it’s not a dealbreaker. The design is compact enough to fit in a small backpack or even a large pocket. The included wrist strap is a nice touch—I use it when I’m kayaking or hiking near waterfalls to avoid accidental drops.

Waterproof Performance: Diving Into the Details

Depth Rating and Real-World Testing

Yi claims the case is waterproof up to 40 meters (131 feet). I’ve tested it at depths up to 30 meters while snorkeling and scuba diving, and it held up perfectly. At 30 meters, the water pressure is about 4 atmospheres, and the case didn’t budge. I didn’t push it to 40 meters—safety first!—but other users on diving forums have reported successful dives at that depth.

Here’s a real-world example: During a trip to the Great Barrier Reef, I filmed a school of clownfish at 25 meters. The case stayed dry, and the footage was crisp. The only minor issue? The lens port fogged up slightly after a long dive, but this is common with any waterproof case and can be avoided with anti-fog inserts (more on that later).

Temperature Resistance: From Ice to Tropical Waters

The case handles temperature extremes well. I’ve used it in icy lakes (around 2°C/35°F) and tropical waters (30°C/86°F). The rubber seals stayed flexible in the cold, and the polycarbonate didn’t warp in the heat. However, I noticed that in very cold conditions, the buttons became a bit stiff, which made adjusting settings underwater tricky. A small gripe, but worth mentioning.

Pressure Changes: Air Travel and High Altitudes

If you’re flying with the case, don’t forget to open it briefly during ascent and descent. The pressure changes can create a vacuum, making it hard to open the case later. I once landed in Denver (high altitude) and couldn’t get the case open until I released the pressure. Now, I always crack the latch mid-flight—problem solved!

Functionality: How It Enhances Your Camera Experience

Lens Clarity and Image Quality

The flat lens port is designed to minimize distortion. I’ve compared footage from the Yi case and a third-party dome port, and the difference is noticeable. The Yi case produces sharper images with less chromatic aberration. However, the flat port can cause glare in bright sunlight. To fix this, I use a lens hood (sold separately) or angle the camera slightly away from the sun.

One thing to note: The lens port is fixed, so you can’t use external filters or wide-angle lenses. If you’re into creative underwater photography, this might be a limitation. For most users, though, the standard port is fine.

Button Access and Controls

The case has raised silicone buttons that align perfectly with the Yi camera’s controls. I can easily press the shutter, mode, and power buttons, even with thick dive gloves. The buttons have a tactile feel, so you know when you’ve pressed them—no guessing games underwater.

Tip: Before your dive, practice adjusting settings in the case on land. It’s easier to get familiar with the button layout when you’re not fighting currents or low visibility.

Audio and Microphone Performance

Waterproof cases always muffle sound, and this one is no exception. The Yi case has a small hole for the microphone, but it’s not ideal for recording audio underwater. For vlogs or interviews, I recommend using an external mic (if your Yi model supports it) or syncing audio in post-production. That said, the mic hole works surprisingly well for ambient sounds, like waves or boat engines, in dry conditions.

Compatibility and Accessories: What Works (and What Doesn’t)

Camera Compatibility

The case is designed specifically for Yi Sports Action Cameras, including the Yi 4K, Yi 4K+, and Yi Lite. I’ve tested it with my Yi 4K+, and it fits snugly—no wobbling or gaps. However, it won’t work with non-Yi cameras or other action cams like GoPro or DJI. If you’re using a third-party camera, check the dimensions carefully.

Battery and Charging

You can’t charge the camera while it’s in the case, which is a bummer. I’ve had to plan my shoots around battery life. On the bright side, the case doesn’t block the battery compartment, so swapping batteries is quick and easy. Just remember to power off the camera before removing the case to avoid accidental button presses.

Mounting Options

The case has a standard 1/4-inch tripod mount and a GoPro-style mounting bracket. I’ve used it with chest straps, handlebar mounts, and suction cups—no issues. The mounting points are reinforced, so they won’t crack under stress. One thing I wish Yi included: a quick-release plate for faster camera swaps.

Useful Accessories

• Anti-fog inserts: These little desiccant pads absorb moisture and prevent lens fogging. I use them for every dive.
• Lens hood: Reduces glare and protects the lens from scratches.
• Replacement seals: Always keep a backup O-ring in your gear bag.

Real-World Use Cases: From Diving to Desert Adventures

Underwater Filming

The Yi case is a game-changer for underwater content. I’ve filmed coral reefs, sea turtles, and even a shipwreck at 20 meters. The case keeps the camera dry, and the lens clarity is impressive. Just remember to rinse it with fresh water after saltwater dives to prevent corrosion.

Rainy and Dusty Conditions

I’ve used the case in monsoon rains and desert sandstorms. The seals held up, and the camera stayed protected. The rubberized edges also help with grip—I’ve dropped it less often than with my old case.

Extreme Sports

Whether you’re skiing, mountain biking, or paragliding, the case can handle the shocks. I’ve crashed my bike with the camera mounted to my helmet, and the case absorbed the impact without damage. The only downside? The added bulk can make the camera feel heavier during high-speed activities.

Travel and Daily Use

The case is great for travel. I’ve taken it on trains, buses, and even crowded markets. The wrist strap gives me peace of mind, and the compact size fits in most daypacks. Plus, it doubles as a protective case for storage when I’m not using the camera.
