If you want your AirPods to finally stay put during a run, choose WC HookZ; if you need to protect a Baseus Bowie MC2 charging case from drops and scratches, choose Helvioran Silicone Case.
• WC HookZ biggest strength: Over-ear silicone hooks that hold AirPods 1, 2, 3, Pro 1 and Pro 2 in your ears without the usual "earbud pushed outward" problem.
• WC HookZ biggest trade-off: It fits a fixed list of Apple models only — AirPods 4 and AirPods Pro 3 are explicitly not supported.
• Helvioran Silicone Case biggest strength: A full wrap-around silicone skin for the Baseus Bowie MC2 case, with keychain, lanyard and cleaner kit in the box.
• Helvioran Silicone Case biggest trade-off: It protects the case, not your ears — it does nothing about earbud fit or stability.
• Choose WC HookZ if you own Apple AirPods and the real problem is them falling out mid-workout.
• Choose Helvioran Silicone Case if you own Baseus Bowie MC2 earbuds and want the charging case shielded and easy to clip on.
WC HookZ is a fit-and-retention accessory, not a case. The design brief is narrow and honest: hook over the top of your ear so the AirPod stays seated instead of being pressed outward. That outward push is the classic failure mode of cheap ear hooks, and WC's stated approach is to shape the hook so it sits around the back of your ear rather than against it. If you've ever had an AirPod pop loose halfway through a run, this is the specific problem it's built to solve.
The materials side matters too. It's tempered silicone with rounded edges, which the spec sheet frames as a comfort and durability combination — flexible enough to bend, rigid enough to actually hold. In my view that's the right balance for an ear hook, because a hook that's too soft does nothing and one that's too stiff becomes painful after twenty minutes. The 5 x 4.09 x 0.59 inch dimensions and 1.5-ounce weight tell you it's a small, light accessory rather than something bulky hanging off your ear.
Who should skip it: AirPods 4 and AirPods Pro 3 owners — the compatibility list stops at AirPods 1, 2, 3, Pro 1 and Pro 2, and there's no version for the newer shapes. Skip it too if your AirPods already fit perfectly; you'd be adding an accessory to fix a problem you don't have. And if what you actually want is protection for a charging case, WC HookZ isn't that product at all.
Helvioran Silicone Case: Who It's For
The Helvioran Silicone Case solves a completely different problem. It's a soft silicone skin that wraps the Baseus Bowie MC2 charging case, covering the shell against scratches, drops and the general wear of living in a pocket or bag. The cutouts are precise enough that you can keep charging without pulling the case off, and the front LED stays visible so you can check status at a glance. That last detail sounds minor until you've owned a case cover that hides the light.
The kit is the interesting part. Alongside the skin you get a keychain, a lanyard and a cleaner kit. Clipped to a backpack strap or belt loop, the lanyard turns the case into something you can grab without digging through a bag — genuinely useful if you commute, travel or move between gym and office a lot. The cleaner kit is a small but sensible addition for keeping both the case and the earbuds free of lint and earwax buildup. It's a slim-fit design in green silicone with a nature-inspired pattern, and it's also described as having a waterproof shell, which adds a bit of reassurance against splashes and rain.
Who should buy it: Baseus Bowie MC2 owners who carry their case loose in a bag, want a visible charging indicator, and like the idea of a lanyard plus cleaning tools bundled in. It's an everyday-carry accessory rather than a performance one.
Who should skip it: Anyone without Baseus Bowie MC2 earbuds — the fit is model-specific, so it won't correctly wrap a different case. Skip it as well if you keep your case in a hard shell or a dedicated pouch already, or if you dislike any added bulk, even the slim kind. And if your complaint is that your earbuds fall out of your ears, this product has nothing to offer — it never touches your ears.
• Best for earbuds falling out while running → WC HookZ. Retention is the entire point of the design.
• Best for protecting a charging case from drops and scratches → Helvioran Silicone Case. Full wrap-around coverage that stays on during charging.
• Best for Apple AirPods owners → WC HookZ. It's built specifically for AirPods 1, 2, 3, Pro 1 and Pro 2.
• Best for Baseus Bowie MC2 owners → Helvioran Silicone Case. The fit is cut for that exact model.
• Best for carrying convenience → Helvioran Silicone Case. Keychain and lanyard come included for clipping onto a bag or belt loop.
• Best for long-session comfort → WC HookZ. Rounded silicone edges and two size pairs are aimed at all-day wear.
• Best for keeping gear clean → Helvioran Silicone Case. The bundled cleaner kit handles the case and earbuds.
• Best if you own newer Apple models (AirPods 4, AirPods Pro 3) → neither. WC HookZ doesn't list them as compatible.
In my opinion, WC HookZ is the one I'd buy — but only if you own one of the Apple models it supports and your actual problem is earbuds working their way loose. It addresses a real, specific frustration, uses a material spec that makes sense for something that bends constantly, gives you two size pairs to tune the fit, and backs it with a 365-day warranty. The Helvioran Silicone Case is a well-put-together accessory with a genuinely useful kit, but it's a case — it protects a Baseus case, it doesn't keep earbuds in your ears. Buy based on the problem you actually have, not the accessory that sounds more protective. And before you commit to either, check the current price on Amazon using the button on this page.
No. The compatibility list covers AirPods 1, 2, 3, AirPods Pro and AirPods Pro 2. AirPods 4 and AirPods Pro 3 are explicitly not supported, so check your model before buying.
It's designed specifically for the Baseus Bowie MC2 open-ear earbuds. The cutouts and LED window are positioned for that case, so a different model won't seat properly.
Yes — charging with the case on is one of the stated features, and the front LED stays visible so you can check charging status without peeling the cover off.
WC HookZ includes two size pairs, an instruction manual and a 365-day full warranty. The Helvioran Silicone Case includes a keychain, a lanyard and a cleaner kit, but the sheet lists no warranty term.
