How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a secure, noise-isolating fit that comes from the tip itself and is made specifically for Apple AirPods Pro, choose COMPLY Memory Foam Replacement; if you need a cheap way to keep a wide range of earbuds from slipping out during runs, choose LOCZUK 50pcs.
• COMPLY Memory Foam Replacement — biggest strength: body-heat activated True Memory Foam that molds to your ear canal for a locked-in, noise-blocking fit built for AirPods Pro Gen 1 & 2.
• COMPLY Memory Foam Replacement — biggest trade-off: it's a precision part for one earbud family only, and it needs gentle hand-cleaning with warm water to stay in shape.
• LOCZUK 50pcs — biggest strength: a 50-piece bulk pack of flexible PC plastic ear hooks that slide onto earbuds with 6.0mm posts and survive repeated bending.
• LOCZUK 50pcs — biggest trade-off: it's a pure anti-slip bracket, not a tip — it does nothing for sound or noise isolation, and it ships with no warranty.
• Who each is for: COMPLY for AirPods Pro owners who want comfort, isolation and a tip that won't fall out; LOCZUK for anyone with hook-compatible earbuds who wants spares for the gym, trail or daily commute.
This is a replacement earbud tip, not an accessory bracket. It swaps out the silicone tips on Apple AirPods Pro Generation 1 and Generation 2 for Comply's True Memory Foam in Lilac Purple, and the material is the whole point. Body heat activates the foam so it slowly adapts and molds to the shape of your ear canal instead of pressing against it like a stiff silicone dome. If silicone tips have ever left your ears sore after a long call or a full album, that's the exact problem this design targets.
The secure-fit story here is about grip and depth. Memory foam creates more surface contact and friction inside the canal than silicone, so the tip stays put when you're moving — the manufacturer frames it as staying secure whether you're pounding the pavement or just listening at your desk. The tip is also cut to a specific length and shape for the AirPods Pro nozzle, which is why Comply positions it as an optimal in-ear fit rather than a universal one. The practical knock-on effect is passive noise isolation: blocking outside sound lets you hear detail at lower volumes, which is friendlier on your ears over time.
LOCZUK 50pcs: Who It's For
This is a completely different kind of accessory. You get 50 transparent ear hooks — retaining brackets that clip around the earbud and hook over the ear to stop it from working loose. They're molded from a flexible PC plastic compound, so they tolerate repeated bending and stretching rather than snapping the first time you stuff them in a pocket. Each hook measures roughly 1.89 x 1.34 x 0.35 inches and weighs almost nothing individually, though the full 50-piece lot comes in at about 27.22 g.
The fit logic is mechanical, not acoustic. A reinforced holding structure clamps the earbud body and the curved hook rests behind your ear, so the bud stays anchored during jogging, hiking and other strenuous movement. The surface is described as pliable and mild on skin, which matters when you're wearing them for hours — the goal is to avoid the rubbing that rigid plastic hooks cause. Installation is deliberately simple: slide the hook frame onto the earbud and go. No tools, no adhesive, no extra supplies.
The catch is compatibility. These hooks are designed for earbuds with 6.0mm connecting posts, and LOCZUK describes that as a wide matching range across multiple earphone styles — but it is still a spec you have to check before buying. They're also clearly positioned as spare fittings: the transparent look means they disappear against most buds, and the 50-piece count is aimed at people who lose or break hooks regularly. Be aware there's no warranty on this product. Who should skip it: anyone expecting better sound or noise isolation, and anyone whose earbuds don't have a 6.0mm post to mount onto.
• Best for a secure fit that also blocks noise → COMPLY Memory Foam Replacement. The foam tip does the gripping and the isolating at once.
• Best for pure anti-slip on the move → LOCZUK 50pcs. A hook physically anchors the bud; it's the more direct answer to "my earbud keeps flying out."
• Best for AirPods Pro 1 & 2 owners → COMPLY Memory Foam Replacement. It's built for that exact nozzle and won't interfere with charging.
• Best for mixed earbud collections → LOCZUK 50pcs. One pack covers most buds with 6.0mm posts, so you're not buying a different tip for each pair.
• Best for comfort over long sessions → COMPLY Memory Foam Replacement. Heat-activated foam adapts instead of pressing, which is the whole reason to move off silicone.
• Best for people who lose accessories constantly → LOCZUK 50pcs. Fifty hooks means a lost one is a shrug, not a reorder.
• Best for low-maintenance ownership → LOCZUK 50pcs. Rinse-free, no special cleaning rules, just bend and reuse.
• Best for a single, tidy upgrade → COMPLY Memory Foam Replacement. One precision part that changes how your AirPods Pro feel and sound.
In my opinion, the right pick comes down to what's actually bugging you. If your AirPods Pro tips slip, ache or let the world leak in, I'd buy the COMPLY Memory Foam Replacement — the memory foam tackles fit, comfort and isolation in one move, and it's made for your exact model. If your problem is an earbud that won't stay hooked during a run and you own buds with 6.0mm posts, I'd buy LOCZUK 50pcs instead; fifty flexible hooks solve that specific job and leave you stocked with spares. They're not competitors so much as two fixes for two different failures. Check the current price on Amazon for whichever one matches your problem.
If silicone causes soreness or slipping, the design addresses both: body-heat activated foam molds to your ear for a customized fit and adds grip plus passive noise blocking. For AirPods Pro owners chasing comfort and isolation, that's a meaningful change rather than a cosmetic one.
Only if your earbuds have 6.0mm connecting posts. LOCZUK lists that as the fitting spec and says the hooks suit most wireless earbuds with those posts across multiple styles. Measure or check your bud's post before ordering, because there's no universal guarantee.
No. They're anti-slip retaining brackets, so they keep the earbud anchored during jogging, hiking and daily use. Any change in sound comes from the bud sitting more consistently in your ear, not from the hook itself.
Clean them gently with warm water and a soft cloth. Avoid alcohol-based cleaners and lotions, since Comply states those can degrade the memory foam. Skip that step and the material won't hold its molding behavior for as long.
