• ALXCD Ear Tips Compatible — biggest strength: six pairs of soft silicone tips in S/M/L sizes, specifically shaped for the JBL Endurance Race, with a sound-isolating design that reduces ambient noise.
• ALXCD Ear Tips Compatible — biggest trade-off: it only fits the JBL Endurance Race. It does nothing for Sony or Edifier owners.
• TENNMAK Replacement Dust Proof — biggest strength: a 10-pair mix of nylon and metal mesh filters plus tweezers, aimed at keeping Sony and Edifier earbuds clean and unobstructed.
• TENNMAK Replacement Dust Proof — biggest trade-off: it's a filter, not an ear tip. It won't change fit, comfort or isolation, and it requires a fiddly three-step install.
• Who ALXCD is for: JBL Endurance Race owners who want fresh tips in multiple sizes for workouts.
• Who TENNMAK is for: Sony WF-1000XM3/XM4 and Edifier TWS NB2/NB2 Pro owners whose mesh filters are dirty, damaged or missing.
This is a consumable part, and it's honest about that. The ALXCD set is built around one earbud model — the JBL Endurance Race — and it ships as six pairs of silicone tips in small, medium and large, plus a fiber cleaning cloth with the ALXCD logo on it. The material is silicone, the color is black, and the whole pack measures roughly 4 x 3 x 0.4 inches, so it stores flat in a bag or drawer.
What it does best is restore fit. Silicone tips are the part of a TWS earbud that wears out first: they lose their grip, they get stretched, they get lost. On a sport earbud like the Endurance Race, fit is the whole ballgame — a tip that doesn't seal properly kills bass and lets outside noise in. The sound-isolating design here is meant to reduce ambient noise, which matters if you're chasing deep bass on in-ear headphones for exercise and don't want to crank the volume to compensate for a bad seal.
Who should buy it: JBL Endurance Race owners who've lost or worn out their original tips, or who want to experiment with sizing. Having S/M/L in one pack is genuinely useful because the correct size is often not the one that came installed, and it can differ between your left and right ear. If you use touch control in-ear headphones for exercise, a proper seal also keeps the earbud stable so your taps land where you mean them to.
Who should skip it: anyone who doesn't own the JBL Endurance Race. This isn't a universal tip. It's also not the right purchase if your problem is a blocked filter rather than a worn tip — silicone tips don't fix clogged mesh.
This is the opposite kind of product: a repair kit for a specific failure mode. The TENNMAK pack is a dust-proof filter replacement set for Sony WF-1000XM4, WF-1000XM3, Edifier TWS NB2 and Edifier TWS NB2 Pro. It arrives with five pairs of nylon dust mesh and five pairs of metal mesh, plus a pair of tweezers to do the job. The color is black and gold, and the mesh is made of metal and nylon.
The point of a mesh filter is to sit between your ear and the earbud's sound tube, catching earwax, dust and debris before it reaches the driver. When that mesh gets saturated or torn, sound gets muffled and unbalanced. Replacing it is the difference between a pair of earbuds that sounds wrong and a pair that sounds like itself again.
TENNMAK's own replacement process is three steps: remove the old mesh with the tweezers and clean the earbud tube; pick up the new mesh with the tweezers; then place it on the tube and press several times to seat it. That's a small job, but it demands a steady hand — these are tiny parts, and the tweezers are included for a reason.
Who should buy it: Sony WF-1000XM3 or WF-1000XM4 owners, or Edifier TWS NB2 / NB2 Pro owners, whose filters are visibly dirty, dented or missing. The 10-pair count is generous, which means you can refresh both earbuds and still have spares for the next cleaning cycle. There's also a stated 90-day warranty after purchase, which is more coverage than most small accessory packs offer.
Who should skip it: anyone who doesn't own one of those four earbud models, and anyone hoping this will change how the earbuds fit. It won't. It's a maintenance part, not a comfort upgrade.
Side-by-Side: Which Should You Choose?
• Best for Sony WF-1000XM3 / XM4 owners → TENNMAK Replacement Dust Proof. The mesh is sized for those sound tubes.
• Best for Edifier TWS NB2 / NB2 Pro owners → TENNMAK Replacement Dust Proof. Same reasoning, different model list.
• Best for fixing fit, comfort and seal → ALXCD Ear Tips Compatible. Silicone tips are what control fit and isolation.
• Best for fixing muffled or degraded sound from a clogged filter → TENNMAK Replacement Dust Proof. A blocked mesh is a filter problem, not a tip problem.
• Best if you want the most pieces and the most spares → TENNMAK Replacement Dust Proof. Ten pairs of mesh plus tweezers versus six pairs of tips.
• Best if you want a tool-free swap → ALXCD Ear Tips Compatible. Tips pull off and push on; mesh filters need tweezers and a careful press.
• Best for combining with a workout routine → ALXCD Ear Tips Compatible. Fresh tips on a sport earbud directly affect how stable it feels during exercise.
If I owned a pair of JBL Endurance Race earbuds and the fit had gone soft, I'd buy the ALXCD Ear Tips Compatible — it's the direct fix, it comes in three sizes, and it addresses the part that actually affects comfort and isolation for exercise. If I owned Sony WF-1000XM3/XM4 or Edifier TWS NB2/NB2 Pro earbuds and the sound had gone dull, I'd buy the TENNMAK Replacement Dust Proof instead, because no ear tip on earth fixes a clogged mesh filter. In my opinion, the deciding question isn't which product is better — it's which earbuds are in your ears. Match the product to your model and neither one will disappoint you.
what is tws earbuds
TWS stands for "true wireless stereo" — earbuds with no wire between the two sides. Both products here are accessories for TWS earbuds: the ALXCD tips fit the JBL Endurance Race, and the TENNMAK mesh fits the Sony WF-1000XM3, WF-1000XM4, Edifier TWS NB2 and Edifier TWS NB2 Pro.
what is tws earbuds means
It means each earbud connects independently and the pair links to your phone without a cable running between them. That design is exactly why these two accessories exist: TWS earbuds have small silicone tips and tiny mesh filters that wear out or clog, and both are replaceable rather than a reason to replace the earbuds.
how to tws earbuds
For the TENNMAK filter, the process is remove the old mesh with the included tweezers, clean the earbud tube, place the new mesh and press it several times to seat it. For the ALXCD tips, you simply pull the old silicone tip off and push the new one on, choosing whichever of the S/M/L sizes seals best in each ear.
how much is tws earbuds
That depends entirely on the model, and it's not something I can quote here — check the current price on Amazon using the button on this page for either accessory. What I can say is that both of these are maintenance parts rather than full earbuds: the ALXCD pack contains six pairs of silicone tips, and the TENNMAK pack contains ten pairs of mesh filters plus tweezers.
