• Pyhsz Charging Case Replacement — biggest strength: built for the 4th generation only, with a fast-charging claim of 5 minutes of charge for about 1 hour of listening and a full earbud top-up in roughly 30 minutes.
• Pyhsz Charging Case Replacement — biggest trade-off: it fits just the 4th-gen models, and neither the earbuds nor a Type-C cable come in the box.
• Huunad Replacement — biggest strength: a 450mAh built-in battery that the brand says delivers up to 5 full recharges, with a pairing sync button for simple setup.
• Huunad Replacement — biggest trade-off: it does not support Find My or magnetic charging, and the warranty is shorter than Pyhsz's.
• Who each pick is for: go Pyhsz if you own 4th-gen AirPods and want quicker charging; go Huunad if you're reviving a 1st or 2nd gen set and want a straightforward, lightweight case.
The Pyhsz case is a single-purpose product, and that's the point. It is designed only for the 4th generation earbuds, covering models A3053, A3050, A3054, A3056, A3055 and A3057. If you own any other generation — 1st, 2nd, 3rd or a Pro model — this is not the case for you, and the listing is upfront about that. For 4th-gen owners, though, the fit and features are aimed exactly at what that generation needs.
The headline feature is charging speed. Pyhsz states that 5 minutes of charging gives you about 1 hour of listening time, and that completely drained earbuds reach full charge in around 30 minutes. The case itself takes roughly 2.5 hours to top up. You get two ways to charge it: a Type-C port and wireless charging. Keep in mind the earbuds and the Type-C cable are not included — this is the case only, so you're replacing the shell, not the whole set.
In my opinion, this is the pick for someone with 4th-gen AirPods whose original case was lost, damaged or stopped holding a charge, and who wants to keep the wireless charging habit and the auto-connect behavior they're used to. Skip it if you own an older generation — it simply won't fit — or if you want a case that ships with a cable in the box.
Huunad Replacement: Who It's For
The Huunad case plays in a different lane entirely. It's built for AirPods 1st and 2nd generation, covering models A1722, A1523, A2031 and A2032. If your older AirPods still sound fine but the case has given up, this is the kind of replacement that keeps a working set out of the drawer. It comes in white, and the enclosure is ABS plastic — a hard shell, not a soft sleeve.
Charging is where Huunad makes its case. The built-in battery is rated at 450mAh, and the brand claims it charges your earbuds in about 20 minutes while providing up to 5 full recharges. That's the number that matters for a 1st or 2nd gen owner: you're not just restoring the case, you're restoring the multi-day buffer that made the original setup convenient. It supports both wireless and wired charging through a Lightning port.
Pairing uses a physical Bluetooth sync button rather than an automatic handshake. Once you've paired, the case reconnects on its own the next time you use it. Two limitations are stated plainly and are worth repeating: the case does not support Find My, and it does not support magnetic charging. If either of those matters to you, this isn't the right product. The warranty is listed at 90 days, noticeably shorter than Pyhsz's.
It's also compact and light — 9.66 grams, with dimensions of 1.8 x 2.2 x 0.8 inches — so it disappears in a pocket. Huunad also notes that customer support is available if you run into issues.

One honest note on price: I don't quote it here, and the numbers change often anyway. Check the current price on Amazon using the button on this page before you commit, since both are the kind of purchase where a small difference can tip the decision.
If I were buying for myself, I'd pick based on the earbuds in my hand, not on the spec sheet — because these two don't actually compete. They serve different generations. For 4th-gen AirPods, I'd buy the Pyhsz Charging Case Replacement: the faster charging, the Type-C plus wireless flexibility, the upgraded Bluetooth chip and the two-year warranty make it the more complete replacement. For 1st or 2nd gen AirPods, I'd buy the Huunad Replacement — the 450mAh battery and up to 5 recharges are exactly what an older set needs. My overall preference goes to Pyhsz for the longer coverage and the broader charging options.
FAQ
Yes. Huunad lists both wireless and wired charging, with a Lightning port for the wired option. What it does not support is magnetic charging or Find My. If you want the magnetic snap-on behavior, that's a reason to look elsewhere.
Neither one includes earbuds or a charging cable. Both are replacement cases only. For Pyhsz specifically, the listing notes that the earbuds and the Type-C cable are not included, so plan on using a cable you already own.
Pyhsz quotes the faster figures: about 1 hour of listening from 5 minutes of charging, and roughly 30 minutes to fully charge drained earbuds, with the case itself taking about 2.5 hours. Huunad quotes about 20 minutes to charge the earbuds and up to 5 full recharges from its 450mAh battery. Note that these are the brands' own stated figures, not independent test results.
