This is the English edition of a review from my Japanese YouTube channel, iestaLife. I review gadgets from my home studio in Japan, so product links go to Amazon Japan.
Quick take
I swapped my favorite leather AirPods Pro 3 case for the ESR Cyber case for one reason: its lid locks. If you hang your AirPods outside a bag, on a carabiner or a crossbody strap, a lid that will not pop open by accident matters more than looks. It is about 10 g heavier and bulkier than leather, but it also sticks to tilted MagSafe chargers.
What I tested
- ESR Cyber case for AirPods Pro 3, black (list price about ¥3,300 at the time of recording)
- Compared with the leather case I used before (about ¥3,000)
- Carabiner on a belt loop, a Peak Design mobile strap, wired and MagSafe charging
Side by side
| ESR Cyber | Leather case | |
|---|---|---|
 |  | |
| Weight (measured) | 36.3 g | 26.4 g |
| Lid lock | Yes | No |
| On a tilted MagSafe charger | Stays put | Slides off |
What I found
- The lock works. The lid closes with a magnet and then locks. Shaking it on a belt loop did not open it.
- Why I needed it. I once found my leather case wide open on my shoulder strap. With another unlocked earbud case, I have lost an earbud about twice.
- Strap setup. I attach a Peak Design mobile quick-release adapter to the case and clip it to the same strap as my iPhone.
- MagSafe magnet. A magnet in the back holds the case on stand-style MagSafe chargers. My leather case slid off.
- Charging access. The LED is visible through a hole, and the USB-C opening is wide enough for normal cables.
- Fit is tight. Keep the included removal tool. Without it, the case is hard to take off.
Who it is for
- You carry AirPods Pro 3 outside your pocket, on a strap, a bag or a belt loop.
- You charge on a stand-style MagSafe charger.
- If you keep AirPods in a pocket and care about looks, a slim leather case is nicer.

Limitations
This is an early impression, not a drop test. Once the case is on, the strap loop on the AirPods Pro 3 itself is covered, so you use the loop on the case. Prices are Amazon Japan prices in yen at the time of recording.
