How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a glow-in-the-dark, lightweight shell that fits the whole AirPods family and adds a bit of playful style, choose KoovDem Earbuds Cover Compatible; if you need a rugged, locking hard case built specifically for the Beats Powerbeats Pro 2 with a cleaning kit in the box, choose Olytop Compatible. These two cases look like they belong to the same category, but they solve completely different problems. One is about personality and slim protection for AirPods; the other is about heavy-duty security for a sport-focused set of earbuds.
• KoovDem Earbuds Cover Compatible — biggest strength: a luminous quicksand design that glows in the dark, plus broad compatibility across AirPods 1/2/3, AirPods 4 and the Pro series.
• KoovDem Earbuds Cover Compatible — biggest trade-off: the glow effect depends on charging the case in light first, and the elastomer shell is built for everyday knocks rather than extreme abuse.
• Olytop Compatible — biggest strength: a two-piece military-grade hard shell with an integrated clip lock, carabiner and a 3-in-1 cleaner pen, all aimed at serious protection.
• Olytop Compatible — biggest trade-off: it fits only the Beats Powerbeats Pro 2 (2025), so it is useless if you own any other earbuds.
• Who KoovDem is for: AirPods owners who want slim, stylish, glow-in-the-dark protection and a keychain to keep the case attached.
• Who Olytop is for: Powerbeats Pro 2 owners who want a rugged locking case they can clip to a bag and clean with a dedicated kit.
KoovDem Earbuds Cover Compatible is a slim elastomer shell with a liquid quicksand design that absorbs ambient light and then glows neon in the dark. It is listed as compatible with AirPods 1, 2 and 3, plus AirPods 4 and the Pro series. In the navy blue (deep sea blue) colorway, it reads as understated in daylight and only reveals the luminous effect once the lights go down, which is a nice touch for anyone who has ever fumbled around a dark room looking for a case. The shell is described as lightweight and slim while still protecting against drops, scratches and bumps, and the precise cutouts mean you can charge with the case on, wired or wirelessly.
Two luminous stickers (6.8cm x 12cm) are included, so you can personalize the case or another surface. Like the case itself, the stickers need a good charge from sunlight on a sunny day to shine through the night. There is also a keychain so you can attach the case to a bag or finger, which is genuinely useful if you tend to misplace small accessories. The material is listed as polypropylene in the item details and elastomer in the feature copy, with a hybrid shell type and anti-slip, dust-resistant features.
In my opinion, this is the pick for AirPods owners who treat their case as an accessory, not just armor. It fits people who want a bit of personality, a glow effect for visibility, and a keychain to keep everything together. Skip it if you own Powerbeats Pro 2 (it will not fit), or if you want a hard locking shell for extreme conditions. The 30-day warranty description is also worth noting if you like a safety net, though it is short compared to what some rugged cases imply.
Olytop Compatible is a very different animal. It is a two-piece hard case designed precisely for the Beats Powerbeats Pro 2 (2025) only, with an integrated clip lock that keeps the case securely closed and prevents accidental openings. The two separate pieces allow the Powerbeats Pro 2 a flexible opening, which matters because these earbuds have a hook design that needs room to move. The shell is described as military-grade, absorbing impacts and protecting against everyday wear and tear, and the material is thermoplastic polyurethane in an electric orange sports pattern.
What makes this case stand out is the bundle. You get the cover case, a 3-in-1 cleaner kit pen, a spare adhesive tape, and a carabiner. The cleaner kit includes a flocking sponge, a soft brush and a metal pen tip, and it is meant for headphones, keyboards, phones and cameras, not just the case. At 0.4oz and 3.95in long with a 0.53in diameter, the pen is small enough to live in a bag pocket without adding bulk. The carabiner lets you clip the case to a backpack or belt loop, which fits the sporty, active use case these earbuds are built for.
In my opinion, this is the case for someone who wears Powerbeats Pro 2 at the gym, on runs or on a bike and wants zero chance of the case popping open in a bag. The trade-off is obvious: it only fits one specific model, and it is a hard shell, so it adds more bulk than a slim elastomer cover. If you own AirPods, this product is simply not for you. If you own Powerbeats Pro 2 and want a rugged, locking, clip-on setup with a cleaning tool thrown in, it is a very focused solution.

If I were buying for AirPods, I would choose KoovDem Earbuds Cover Compatible. In my opinion, the combination of broad AirPods compatibility, a slim elastomer shell, glow-in-the-dark quicksand styling, two luminous stickers and a keychain makes it the more versatile and more fun everyday case. I would choose Olytop Compatible only if I owned Beats Powerbeats Pro 2 and wanted a rugged locking hard shell with a carabiner and cleaning kit. The two do not really compete head-to-head; they serve different earbuds and different owners, so match the case to your model first and your lifestyle second.
No. KoovDem is a slim elastomer glow-in-the-dark case for AirPods 1/2/3, AirPods 4 and the Pro series. Olytop is a rugged hard locking case for the Beats Powerbeats Pro 2 (2025). They fit different earbuds entirely.
No. Olytop Compatible is designed precisely for the Beats Powerbeats Pro 2 2025 only. If you have AirPods, you want the KoovDem case, which covers the AirPods 1/2/3, AirPods 4 and Pro models.
It needs to absorb sufficient light first. The quicksand design and the included stickers charge from sunlight on a sunny day and then glow through the night, so the effect depends on how much light they get beforehand.
KoovDem includes the glow case, 2 luminous stickers (6.8cm x 12cm) and a keychain. Olytop includes the cover case, a 3-in-1 cleaner kit pen, a spare adhesive tape and a carabiner. Both are complete kits for their respective earbuds.
Value depends on which earbuds you own, since neither case fits the other's model. Compare the included accessories and check the current price on Amazon before deciding, because the bundles and materials differ a lot.
