Size: AirPods 4
Color: Translucent Grey
I bought this case for my AirPods 4 and the first thing that caught my attention was the design. From the outside, it immediately reminded me of the Tesla Cybertruck with its sharp lines and industrial look. It looks great, but this case is not just about aesthetics. The build quality is extremely solid. Honestly, even if you dropped it from a very high place, it feels like your AirPods would still be fully protected. It’s that sturdy. One detail I really appreciate is the locking mechanism. With regular cases, the lid can open when dropped and the AirPods can fly out. That risk is completely eliminated here. The lock keeps everything securely in place, which is a very smart design choice. I also tested wireless charging and had zero issues. As soon as I placed it on the charger, it was detected immediately and started charging without any interruptions. Overall, this is a well-thought-out, durable, and premium-feeling case. It offers both strong protection and a unique design. I’m very happy with it and would definitely recommend it.

First of all, there is a lot of competition when it comes to AirPod cases. So looking at negative reviews… I would take many with a grain of salt. They do not accurately describe the quality of this case! The case is first of all unique in style, not going to find another one like it on Amazon. Secondly, it does not look or feel cheap in quality. There is a very nice metal latch with a spot for the light to show from the AirPod Case. A very nice adjustable strap loop that is durable and impact resistant rubber that is not too soft or too hard. There was mention of the case falling apart, and that is not possible on the concept of pure physics. The top latches on to the bottom and there is no way to get enough flex to have the top come off it also snuggly fits the case on both top and bottom and comes with an adhesive strip for the top. It uses double sided tape so you peel off the bottom portion place on the top of the case, and then pull off the blue clear plastic to expose the second adhesive side in which the case gets placed on top of. One of the troubling things from previous reviews on this case was estimating the size. If you other reviewers showed the case in their hand, but who knew what size their hand is… In this photo, there is a picture of the case placed on top of a standard size Post-it note the case is smaller in width than a credit card and slightly higher. A small downside is no MagSafe option however, the charging port is easily accessible. Not a big problem if you’re used to plugging in your AirPods to charge. I would definitely recommend this case, especially on sale you cannot go wrong with this choice. Even though a few small setbacks the advantage of style, durability and quality make this a winner.

This is a solid case and well-designed. It fits the AirPods perfectly, and I like the look a lot. It is not a slim case, but seems very protective. The main blind spot is the strap. The metal loop looks cool, and is solid, but the strap slides out of it nearly every time it is in my pocket, making the strap completely unreliable. I'd love to see a fix from Aulumu!

Looks nice but the top cover will not stay in place. Falling all the time, having to hold it every time I use/put away my headphones. Worst case I’ve ever bought. Waste of money.

Amazing AirPods case! A little chunky but let’s be honest, if you’re buying this case it’s because of the design and not the slim form factor. The lock mechanism seems sturdy and the strap has been so handy to attach to my keys or backpack. I was worried about the strap slipping off the case due to the open strap attachment loop on the case, but haven’t had any issues with that!

The media could not be loaded. This Aulumu A09 case is a definite standout. Its futuristic design, reminiscent of a Tesla Cybertruck, is undeniably cool. The all-encompassing rubber casing provides excellent protection, and the aluminum locking tab adds an extra layer of security. Installation is a breeze. The case feels solid in hand and offers great peace of mind. The interesting use of mixed materials—matte finished aluminum, rubber, and hard plastic—creates a unique and durable case. I appreciate innovative and futuristic designs. However, form should never compromise function. While the case provides easy access to the USB-C charging port, unfortunately, wireless charging doesn't work for me with this case on. The case's sleek design is initially appealing, but its functionality is severely compromised by a critical design flaw. The uneven weight distribution caused by the oversized rubber feet results in a misaligned charging surface, rendering the case incompatible with wireless charging. This fundamental error undermines the core purpose of the product, which is to provide convenient wireless charging for AirPods Pro. While the design is top-notch, there are a couple of minor issues. The finishing on the aluminum could be smoother, with less sharp edges. Additionally, the lanyard slot feels like an afterthought, as it's clearly cut and grinded rather than being part of the original mold. I would have preferred a fully enclosed hole for easier attachment to a keychain. Overall, the Aulumu A09 is a fantastic choice for those seeking a stylish and protective case for their AirPods Pro. With a few small improvements, it could be even better.

Great case, not too bulky, feels premium, the snap shut is very fidgety and satisfying and the lock holds very well. And wireless charging still works which I was worried wouldn’t. You can still open it one handed, you just need an extra finger involved to open the lid while you open the lock. And the case just looks awesome in my opinion.
