⚡ The quick answer
A SpongeBob AirPods case costs €17.90 and is chosen based on the case size first, not the visual design. The AirPods 2 case measures approximately 53 × 44 × 21 mm, the AirPods 3 case approximately 54 × 46 × 21 mm, and the AirPods Pro case approximately 61 × 45 × 22 mm: a case designed for one will not close properly on another. Then check three details: a cutout for the charging port, an opening or transparent area in front of the LED, and a silicone thickness of less than 2 mm if you charge on a wireless pad.

A wireless earbud case lives a brutal existence: it spends its day at the bottom of a pocket with keys, falls off a desk about once a quarter, and its hinge endures dozens of daily openings. After a year, the glossy white is grey, scratched on the edges, and the hinge has developed play. None of this is fatal, but all of it is preventable for the price of a case.
The problem is that half of the cases sold online are vaguely described: "AirPods compatible" without specifying the generation, even though three case formats coexist and they don't look alike. A case that's too big gapes and lets the case slide out; a case that's too small prevents the lid from closing completely, which interrupts earbud charging without you realizing it.
This guide covers the three checks to make before buying, then details the materials, the issue of wireless charging, and maintenance. It's the same method applied in our phone case guide: we start with actual dimensions, not the visual. To place this product within the entire range, our merchandise guide provides an overview.
Compatibility: identify your case in ten seconds
Before any purchase, look at your closed case. Three clues are enough to classify it.
LED position
If the small indicator light is inside, under the lid, you have a first-generation case. If it's outside, on the front below the hinge, you have a later generation. This is the quickest criterion, and it changes everything: a solid case on a case with an external LED will obscure the charging indicator. The latest models available in store are grouped under new arrivals.
Width
Classic AirPods cases are significantly taller than they are wide, with a base of about 44 mm. The Pro model case is wider than it is tall, around 61 mm wide by 45 mm high: it's immediately recognizable when laid flat. A Pro case on a classic case will leave more than a centimeter of lateral play.
Charging port
Recent generations have transitioned from the Lightning port to USB-C. The bottom cutout of a case is generally wide enough to accommodate both, but check that the cable inserts fully without forcing: a half-inserted connector heats up and damages the port. The same principle applies to phone cases and all portable accessories.
Silicone, TPU or plush: what's the difference
Three families share the market, with very different characteristics.
Soft silicone
This is the standard, and by far the most versatile. Usual thickness: 1.2 to 1.8 mm. It absorbs falls from low heights, grips well in the hand, doesn't scratch the case, and is easy to remove for cleaning. It has two known drawbacks: it attracts dust and pocket lint, and clear silicones yellow slightly after a year or two. Nothing dramatic, but it's good to know before choosing a white model.
Rigid TPU
Harder, thinner, visually sharper. It preserves print details with a precision that silicone cannot achieve, which matters when you want a well-defined face of SpongeBob or Patrick. On the other hand, it transmits shocks more, and can crack at a corner after a fall on tile.
Plush and 3D models
Very expressive, with reliefs, ears, or character shapes. They protect well against shocks due to their thickness, but they pose two practical problems: they no longer fit into a small pocket, and their thickness often exceeds 4 mm, which blocks charging on an induction pad. Best reserved for bag use. If you like plush items, our plush guide covers the topic in large format, and the plush collection brings together all the characters.
What a case really protects
Let's be precise, because marketing promises are generous.
Scratches: yes, completely
This is the main benefit and it's real. A lacquered case shares a pocket with keys, a small leather good, and coins: without a case, it gets scratched in a few weeks. With one, it emerges intact after two years, which matters on resale day. The simplest remedy is still to separate your keys, for example on a carabiner keychain.
Falls: partially
A 1.5 mm silicone case handles a fall from a desk (about 75 cm) onto parquet or carpet very well. On tile and from more than a meter, it cushions without guaranteeing protection. What it protects best are the four corners, which are exactly the areas that hit the ground first.
Hinge: indirectly
The weak point of all cases is the hinge. A case doesn't reinforce it, but it prevents the lid from opening wide in a pocket, which limits mechanical stress. Choose a model where the top part is attached to the bottom part rather than a case in two independent pieces.
Water: no
No case of this type is waterproof. It slows down the penetration of a splash, nothing more. If the case gets wet, remove the cover immediately, otherwise the moisture will remain trapped against the plastic.

Earbud and speaker protectors, and desk surfaces.
Wireless charging, LED, and cutouts
Three technical details determine daily comfort. They cost zero euros to check and ruin the experience if missed.
Induction works under 2 mm
A silicone case between 1.2 and 1.8 mm thick does not block charging on a Qi pad: the field passes through without difficulty. Beyond 3 mm, and especially with a plush case or a thick relief model, charging becomes slow or intermittent. If your pad heats up abnormally, this is the first parameter to test: remove the case and try again.
The LED must remain visible
On a case with an external indicator, an opaque front cover will deprive you of charging information. Look for a round cutout or a translucent strip at that precise spot. On a case with an internal LED, this question does not arise.
Carabiner, useful but to be monitored
Most cases include a ring and a small carabiner. This is practical when hooked to a bag loop, but the ring is the breaking point: it's the first thing to give way after a few months of swinging. If you care about your earbuds, it's better to hook the case inside a zipped pocket or use a more robust keychain carabiner, or even a strap on a backpack.
| Material | Thickness | 75 cm drop | Qi charging | Jean pocket |
|---|---|---|---|---|
| Soft silicone | 1.2 to 1.8 mm | Absorbed | Yes | Yes |
| Rigid TPU | 1 to 1.5 mm | Transmitted | Yes | Yes |
| Plush / 3D | 4 mm and up | Highly absorbed | Often no | No, bag required |
💡 Did you know?
An earbud case is opened an average of six to ten times a day, which is over 2,500 cycles per year. It's the hinge, not the outer shell, that determines the actual lifespan of the item. A one-piece case, which limits the opening angle in a pocket, therefore protects more effectively than a model with two independent parts.
Which model for your use
Four situations, four answers.
Daily commutes and jean pockets
Thin silicone, one-piece case, carabiner left aside. You want something that won't snag on anything and will come out without pulling out the lining. It's the same reasoning as for choosing between a cardholder and a compact, explained in our article on wallets. In summer, with shorts with shallower pockets, thinness matters even more.
Backpack and school bag
Here, thickness is no longer an issue. A relief or plush case makes perfect sense, and the carabiner becomes useful for finding the case at the bottom of the bag rather than searching for it under notebooks. This topic connects with organizing a backpack, a well-prepared back-to-school, and a well-compartmented pencil case.
Office and open plan
The case stays on the desk all day: it's a visible object, just like a mouse pad or a mug. A sharply printed TPU is better than silicone that collects dust. Our article SpongeBob at the office details the right balance, and our gift guide for a colleague follows the same logic of discretion.
Gift
At €17.90, it's an effective small gift, in the same range as our under €20 selection. One precaution: ask for the case generation before ordering, otherwise the gift won't close. For a teenager, it's almost always a good choice, as shown in our gift guide for teens; for a younger child, see our gift guide for kids or the gift ideas collection.

What travels in the same pocket or bag as your earbuds.
🧠 Tip
Measure your case with a ruler before ordering, width and height, and note both numbers in your phone. Thirty seconds is all it takes, and you avoid the most common mistake: ordering a Pro model case for a classic case because the visuals look similar on screen.
⚠️ Mistake to avoid
Leaving the case on when the device has gotten damp. Silicone doesn't dry on its own and holds water against the plastic for hours, exactly where the charging contacts are. If in doubt, remove the case, wipe the device, and let both air dry separately before reassembling them.
Care and lifespan
A silicone case gets dirty, that's normal. It cleans up in two minutes.
Cleaning
Remove the case from the device, wash it in lukewarm water with a drop of mild soap, scrub the corners with a soft toothbrush, rinse, and let it air dry completely before putting it back on. Allow two to three hours for drying: putting a damp case back on the device is the best way to damage the charging contacts. The same logic applies to the care of printed products, and the same reasoning about materials as in our article cotton, fleece, or polyester.
Embedded dust
Silicone attracts fibers. A piece of adhesive tape applied then removed cleans the surface much better than a cloth, which only moves lint around.
When to replace it
A silicone case lasts one to two years before stretching out: when it no longer firmly holds the device and slips when opened, it no longer protects. It's a consumable, not an investment, and its price reflects that. It's also an opportunity to change the design.
Delivery, times, and costs
Delivery costs €5.90 in France and the rest of the European Union, and is free for purchases over €60. Outside the European Union, it is €7. The announced delivery time is 7 to 14 business days.
A €17.90 case alone does not qualify for free shipping. Many orders combine it with a t-shirt, a sweater, or a gift set to reach €60. If the package needs to arrive by a specific date, order fifteen days in advance: the announced times are business days, not including weekends. The holiday calendar is detailed in our Christmas guide.
Frequently Asked Questions
How do I know what generation of earbuds I have?
Look at the LED: if it's inside under the lid, it's a first-generation case; if it's on the front outside, it's a later generation. Then, measure the width: about 44 mm for classic models, about 61 mm for Pro models.
Does a case block wireless charging?
No, as long as it remains under 2 mm thick. Plush or thick embossed models, beyond 3 to 4 mm, slow down or interrupt charging on a Qi pad.
Do I need to remove the case to charge with a cable?
No, provided the bottom cutout is wide enough for the connector to fully insert. If you have to force it, remove the case: a partially engaged connector damages the port.
Does the case protect against a fall?
A fall of about 75 cm onto parquet or carpet, yes. On tile and beyond one meter, it cushions without guaranteeing. It's mainly the four corners that are protected. The same principle applies to phone cases.
Does silicone yellow over time?
Clear silicones take on a slightly yellow tint after one to two years. Saturated colors, like SpongeBob yellow or Bikini Bottom blue, do not show this phenomenon.
How do I clean a dirty AirPods case?
Remove it, wash it in warm soapy water with a soft toothbrush, rinse, then let it air dry for two to three hours before putting it back on.
Is the included carabiner reliable?
This is the most frequent breaking point after a few months of swinging. For intensive use, prefer a more robust keychain carabiner or a zippered pocket.
Is this a good low-budget gift?
Yes, at €17.90. The only precaution is to know the generation of the person's case: a case with the wrong size will not close.
An earbud case is a small purchase that goes wrong for only one reason: choosing the design before measuring the case. Grab a ruler, note the width, check the LED's position, and the rest becomes easy. A thin, one-piece silicone cover suits 90% of uses, keeps the case intact for two years, and doesn't interfere with cable charging or induction pads. The design, however, is the only variable where you can indulge without technical arbitration.
