If you want a stylish, protective skin with a built-in cleaning kit for your existing AirPods Pro 1st or 2nd Generation case, choose KOUJAON Compatible; if you need a functional replacement charging unit for the newer AirPods Pro 3rd Generation earbuds, choose korllo A3122. These two products serve fundamentally different purposes in the Apple ecosystem, and confusing one for the other is an easy mistake to make until you read the fine print. One is an accessory designed to dress up and safeguard a case you already own, while the other is a critical hardware component meant to replace a lost or broken charger entirely.
Choosing between these options isn't about which brand has better marketing or flashier colors; it is strictly about matching the product to your specific device generation and your immediate problem. Are you looking to add some personality to your current setup and keep it clean, or are you in a bind because your original charging case is gone? The answer dictates everything. I have analyzed the specifications, materials, and intended use cases for both items to help you navigate this decision without wasting money on incompatible gear. This comparison focuses squarely on how each item performs its core function, ensuring you pick the right tool for your office or daily commute needs.
• KOUJAON Compatible: Offers high-elasticity silicone protection and a decorative keychain with a 3-in-1 cleaning pen, but only covers the exterior of the case rather than replacing internal components.
• korllo A3122: Provides a complete functional replacement charging case with wireless and USB-C capabilities, but requires you to already possess the specific third-generation earbuds.
• Best for: KOUJAON is ideal for those wanting style and maintenance tools for Gen 1/2 users, while korllo is essential for Gen 3 owners needing a new battery hub.
The KOUJAON Compatible case is designed specifically for the user who already owns a working charging case for their Apple AirPods Pro 1st or 2nd Generation models and wants to upgrade the experience. It does not replace the electronics inside your case; instead, it acts as a durable, touch-like shell that wraps around the existing unit. If you are someone who frequently misplaces their earbuds or worries about scratches from keys in a bag, this product addresses those pain points directly. The inclusion of a bling flower keychain is not just aesthetic fluff; it serves a practical purpose by allowing you to attach the case to a belt loop or bag strap, making it significantly easier to locate when rummaging through cluttered pockets or backpacks.
The material choice here is distinctively tactile. This isn't just about comfort; it offers genuine shock absorption against bumps and drops. Unlike rigid plastic shells that might crack under pressure, this silicone material flexes to protect the underlying case. Furthermore, the waterproof nature of the material means that accidental spills or sweat won't ruin the exterior finish. You can wipe away dirt easily, keeping the pink enclosure looking fresh for long-term use. This makes it an excellent choice for the best earphones for office environments where desk spills or casual wear-and-tear are common concerns.

However, this product is not for everyone. It is strictly an external cover. If your original charging case is broken, missing, or has a faulty port, buying this KOUJAON case will not fix your ability to charge your earbuds. You must have a fully functional case to begin with. Additionally, the design is tailored for the first and second generations of AirPods Pro, so it will not fit the newer 3rd Generation models. If you are a woman looking for a gift that combines utility with fashion, this set stands out because it includes a three-part cleaning pen with a metal tip and flocking brush, ensuring your headphones stay dust-free alongside the stylish protection.
The korllo A3122 is a solution for a very specific and urgent problem: losing your charging case or having the original one break beyond repair. This is not a skin or a cover; it is a standalone replacement charging unit designed exclusively for the AirPods Pro 3rd Generation earbuds (models A3064/A3063). If you have recently upgraded to the latest Pro model and lost the box that keeps them powered, this is the hardware you need to get back to using your earbuds. The listing explicitly states that earbuds are not included, emphasizing that this is a pure replacement part for the charging infrastructure.
Functionality is the primary driver for this product. It supports both wired USB-C charging and Qi wireless charging, mirroring the convenience of the original hardware. More importantly, it incorporates robust safety features including over-charge, over-voltage, over-temperature, and short-circuit protection. These aren't just buzzwords; they are critical safeguards that prevent your expensive earbuds from being damaged by power surges or overheating during the charging cycle. In a busy office setting where you might leave your devices plugged in overnight or forget to unplug them, these protections provide peace of mind that your batteries remain healthy. The pairing process is straightforward: simply place your earbuds in the case, open the lid, double-tap the front until the light flashes, and connect via Bluetooth settings.
This product is strictly for the tech-savvy user who knows their exact model number. It is not compatible with any previous generations of AirPods Pro, nor does it work with standard AirPods 3 or 4. If you try to force older earbuds into this case, they simply will not fit or charge correctly. The enclosure is made of ABS plastic, offering a sturdy, white finish that blends seamlessly with the modern aesthetic of the 3rd Gen earbuds. While it lacks the decorative flair of the KOUJAON option, it excels at its single job: getting your audio back online safely. For anyone seeking the best headband headphones for office productivity that rely on seamless connectivity, a reliable replacement case like this is non-negotiable.

I would buy the korllo A3122 if my goal was to restore functionality to a set of lost AirPods Pro 3rd Generation earbuds, because without a working case, the earbuds are essentially useless. However, for most people looking to enhance their daily carry, the KOUJAON Compatible case is the more versatile addition to their routine. It transforms a standard piece of tech into something personalized and harder to lose, while also providing a cleaning tool that extends the life of the earbuds themselves. For the office environment, where appearance and reliability matter, the KOUJAON option strikes the better balance of style and practical utility, provided you already have a functioning case. If you are torn between upgrading your look or fixing a broken charger, let your hardware generation be the deciding factor, but personally, I prefer the added value of the cleaning kit and keychain.
