TENNMAK Replacement Dust Proof vs GEEKRIA Earphone Magnetic Anti-Lost at a Glance
• TENNMAK Replacement Dust Proof — biggest strength: it's a complete reseal job in a bag — 5 pairs of nylon dust mesh, 5 pairs of metal mesh and the tweezers you need to do the swap, sized for four specific Sony and Edifier models.
• TENNMAK Replacement Dust Proof — biggest trade-off: it's useless unless you already own one of those four earbuds, and it asks you to handle a tiny mesh disc by hand without losing it.
• GEEKRIA Earphone Magnetic Anti-Lost — biggest strength: a silicone neck strap with a magnet that holds each bud, so a dropped earbud dangles instead of disappearing into a gym floor drain.
• GEEKRIA Earphone Magnetic Anti-Lost — biggest trade-off: the compatibility list is all JBL, so Sony, Edifier, Soundcore and Apple owners are out of luck.
• Buy TENNMAK if your earbuds are muffled, dusty or losing seal and you'd rather refurbish than replace.
• Buy GEEKRIA if you own one of the listed JBL models and you're tired of hunting for a bud on your hands and knees.
This is a consumable-part kit, and the spec sheet says so plainly. You get ten pairs of mesh in total — five nylon, five metal — plus a pair of tweezers, and the enclosure materials are listed as metal and nylon in a black-and-gold finish that reads as a cosmetic match for dark earbuds. The dimensions (5.91 x 3.94 x 0.08 inches) tell you what you're actually handling: a flat, postage-stamp-sized sheet of tiny discs, not a chunky accessory. The whole idea is that the filter mesh on an earbud is a wear item — it collects wax, dust and pocket lint, and when it loads up, the earbud stops sounding like itself. TENNMAK's answer is to swap the mesh rather than the earbuds.
The process as described is refreshingly honest about the fiddliness. You lift the old mesh off with the tweezers, clean the earbud tube, pick up the new disc with the tweezers, paste it on the tube and press several times to seat it. That's it. No adhesive applicator, no jig, no instructions beyond those three steps. In my opinion, that's the right level of complexity for someone who's comfortable with small parts — and a mild headache for someone who isn't.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
Buy it if: you own Sony WF-1000XM4, WF-1000XM3, Edifier TWS NB2 or Edifier TWS NB2 Pro, and you want a multi-year supply of replacement filters plus the tool to install them. The 90-day warranty adds a little reassurance on top.
Skip it if: your earbuds aren't on that four-model list. There's no universal sizing here, and I wouldn't try to improvise a fit on a model the sheet doesn't name. Also skip it if you were hoping for an upgrade — this restores an earbud, it doesn't change how it sounds. And if what you're really shopping for is deep bass clip on earbuds for streaming, this isn't a headphone at all; it's the maintenance kit that keeps a specific pair of headphones alive.
GEEKRIA's accessory solves the opposite problem. Instead of restoring audio, it stops you from losing the hardware in the first place. Each strap is a soft silicone cord with a glossy finish, and the magnet at the business end attracts and locks the earbuds together when you pull them out of your ears, so they hang around your neck instead of dropping.
Installation is described as a few seconds — you push each earbud into a hole in the strap and you're done — and there's a microphone opening at the bottom so the strap isn't sitting over the mic. Two straps come in the pack, which is sensible: one for the bag, one for the gym. The compatibility list is long but narrow: JBL Vibe Beam, Tune Flex, Tune 230NC TWS, Live Beam 3, Live Pro 2 TWS, Vibe 200TWS, Tune Beam, Tune 225TWS, Vibe Flex and Quantum TWS. That's ten JBL models and nothing else.
Buy it if: you own one of those JBL earbuds and your loss risk is real — running outdoors, working out, cleaning the house, cycling through a commute. Hanging a bud around your neck while you talk to someone is also genuinely handy during long streaming sessions when you're pausing constantly.
Skip it if: you don't own a listed JBL model. The strap is molded to fit specific bud shapes, and a loose fit defeats the entire purpose. Skip it too if you dislike anything around your neck, or if you've already solved the problem with a case and a routine.
• Best for clogged or muffled Sony WF-1000XM4 / XM3 → TENNMAK Replacement Dust Proof. It's built for exactly those two models.
• Best for Edifier TWS NB2 / NB2 Pro owners → TENNMAK Replacement Dust Proof. Same logic, and you get ten pairs to work through.
• Best for stopping loss during workouts and runs → GEEKRIA Earphone Magnetic Anti-Lost. The magnet lock plus neck cord is the whole point.
• Best for JBL Vibe Beam, Tune Flex or Tune 230NC TWS → GEEKRIA. Those are named on the compatibility list.
• Best for a complete, self-contained job → TENNMAK. Tweezers included, so you're not hunting for a tool at the last minute.
• Best for zero-fuss installation → GEEKRIA. Seconds to fit, seconds to remove, no adhesive and no pressing.
• Best for long-term ownership support → TENNMAK, on the strength of the 90-day warranty and the fact that a ten-pair kit covers repeat replacements.
• Best for keeping a streaming setup clean → TENNMAK if the filters are the weak link; GEEKRIA if you're constantly pulling buds out mid-session and setting them down somewhere you'll forget.
Worth saying plainly, because the product names can mislead: neither of these is a listening device. If you're shopping for usb c charging headphones for streaming, or for deep bass clip on earbuds for streaming, you're in the wrong aisle — both items here are accessories for earbuds you already own. Buy them to protect or repair, not to upgrade your sound.
My Verdict
No. If your model isn't one of those four, this kit isn't the right fit.
Not according to the compatibility list, which is exclusively JBL — Vibe Beam, Tune Flex, Tune 230NC TWS, Live Beam 3, Live Pro 2 TWS, Vibe 200TWS, Tune Beam, Tune 225TWS, Vibe Flex and Quantum TWS. Fit matters here, so I wouldn't force it onto something else.
The design includes a microphone opening at the bottom of the strap, so the mic isn't covered. Beyond that, the sheet describes no change to audio behavior — it's a silicone cord with a magnet, not electronics.
I don't quote prices here. Use the "Check latest price on Amazon" button on this page for both items and compare the current figures yourself, especially since one is a ten-pair kit and the other is a two-pack of straps.
