If you want a purpose-built, model-specific fit for your AirPods 4th Gen — especially for airplane travel — choose Proof Labs 4; if you need a flexible, universal silicone earhook set that works across different earbuds and comes in multiple color options, choose APGLSXY Ergonomic Silicone Earhooks. Both are silicone ear adapters designed to keep earbuds seated, but they solve the problem in very different ways. Here's how they compare when a secure fit earhooks is your main priority.
• Proof Labs 4 — biggest strength: Purpose-built exclusively for Apple AirPods (4th generation), with two sizes in the box (2 Pairs Small, 2 Pairs Large), a storage pouch, carabiner, and a 1 Year Manufacturer Warranty.
• Proof Labs 4 — biggest trade-off: You must remove the hooks before charging, and they only fit AirPods 4th Gen — nothing else.
• APGLSXY Ergonomic Silicone Earhooks — biggest strength: Universal silicone earhooks sold as 3 sets in black/white, designed to add grip and stability to a range of earbuds, with a sports-focused pattern.
• APGLSXY Ergonomic Silicone Earhooks — biggest trade-off: No sizing system and no stated model-specific fit, so how well they hold depends heavily on your particular earbuds.
• Who Proof Labs 4 is for: AirPods 4 owners who want a guaranteed, size-matched hold — and who want it to survive a long-haul flight without fiddling.
• Who APGLSXY is for: Anyone with earbuds that aren't AirPods 4, or who wants a cheap multi-set backup for workouts and commuting.
Proof Labs 4 is not a universal accessory — it's a dedicated one. The product is made specifically for Apple AirPods (4th generation), and that single fact is both its biggest advantage and its biggest limitation. Because it's built around one earbud shape, the fit is a design decision rather than a gamble. The soft, flexible silicone hooks are meant to prevent your AirPods 4 from falling out of your ears, and the package ships with 2 Pairs Small and 2 Pairs Large so you can match the hook to your ear rather than hoping one size works.
This is the set I'd point an AirPods 4 owner toward for a long flight. The hooks create a physical anchor around the back of the ear, which is exactly what you want when you're seated, drifting off, and don't want to dig a loose earbud out from between the seat cushions. The included storage pouch and carabiner also matter more than they sound — they give you a dedicated place to keep the hooks when they're off the buds, which is the moment most small accessories get lost in a carry-on.
The trade-offs are real, though. Proof Labs is explicit that the hooks must be removed before charging, so they aren't a leave-on-and-forget solution. And if you own anything other than AirPods 4th Gen, this product simply isn't for you. What you do get is a clear fit promise: it's backed by the Proof Labs Fit Guarantee and a 1 Year Manufacturer Warranty, and the kit totals 8 pieces (four pairs of hooks plus the accessories), all in white silicone.
Buy it if: you own AirPods 4th Gen, you want a size-matched hook rather than a universal one, and you value having a pouch to keep the set together.
Skip it if: you use non-Apple earbuds, or you want something you can leave on while charging.
APGLSXY takes the opposite approach. Instead of fitting one model perfectly, these are general-purpose silicone earhooks — ear adapters and covers meant to work with a range of earphones. The set includes 3 sets of hooks in black and white, so you get multiple pairs to experiment with. The pitch is broader: improved stability and grip, suitable for men and women, and comfortable enough for all-day wear.
The material story is straightforward. Soft silicone gives the hooks flexibility and durability, and the installation is designed to be easy, so you can move them between earbuds without much fuss. The product is styled with a sports pattern, which lines up with its intended use cases: workouts, commuting, or just relaxing, with the goal of keeping your earbuds in place through all of it. The listing also notes that the hooks are meant to enhance sound by improving the seal and fit — a common claim for this kind of accessory, and one that makes sense when a better-seated bud means less leakage.
Where APGLSXY wins is flexibility and value per piece. Three sets in two colors means you can keep a pair in your gym bag, a pair in your travel kit, and a spare at home. There's no model lock-in, so if you switch earbuds later, the hooks likely still work. The stated compatibility list mentions iPhone 17 as a device, which tells you the brand is positioning these as a broad accessory rather than a precision fit for one product.
Buy it if: you want a multi-set, multi-color pack, you're not tied to one earbud model, or you need spares for the gym and the road.
Skip it if: you want a guaranteed, size-matched fit for one specific earbud — that's not what a universal hook can promise.
Side-by-Side: Which Should You Choose?
• Best for a specific earbud model → Proof Labs 4. It's built only for AirPods 4th Gen, so the fit is intentional, not incidental.
• Best for mixed earbuds or future swaps → APGLSXY. No lock-in, and you get 3 sets to spread across bags.
• Best for size matching → Proof Labs 4. Two sizes (Small and Large) in the box vs. a single universal shape.
• Best for keeping the kit together → Proof Labs 4. Storage pouch, carabiner, and quick start guide are all included.
• Best for color variety → APGLSXY. Black and white options vs. Proof Labs' white-only silicone.
• Best for leaving hooks on while charging → APGLSXY. Proof Labs requires removal before charging; APGLSXY doesn't state that restriction.
• Best for a long-haul flight setup → my pick is Proof Labs 4. If you're an AirPods 4 owner, the size-matched hold and the pouch make it the more travel-ready of the two.
• Best for a low-commitment, multi-purpose backup → APGLSXY. Three sets means you can test, replace, and stash without thinking about it.
My Verdict
For AirPods 4 owners, yes — Proof Labs 4 is built specifically to stop your buds falling out, which is the exact scenario a cramped, reclined seat creates. APGLSXY works too, but the fit is universal rather than model-matched.
Both use soft silicone, which is flexible and forgiving. Proof Labs backs its hooks with a 1 Year Manufacturer Warranty and a fit guarantee; APGLSXY states durability as a design goal but doesn't list a warranty term.
Proof Labs 4 is only for Apple AirPods (4th generation). APGLSXY is the universal option — its hooks are designed for a range of earphones, so it's the better pick if your buds aren't AirPods 4.
