If you want to restore the sound and fit of earbuds you already own, choose TENNMAK Replacement Dust Proof; if you need to protect a pair of JBL Tune earbuds you carry everywhere, choose BOVUGAC Case. These two accessories solve completely different problems, and mixing them up is the fastest way to waste money on cheap TWS gear.
• TENNMAK Replacement Dust Proof — biggest strength: a ten-piece mesh kit with tweezers that refreshes the clogged filters on Sony WF-1000XM3 / XM4 and Edifier TWS NB2 / NB2 Pro earbuds.
• TENNMAK Replacement Dust Proof — biggest trade-off: it only fits those four specific models, and it does nothing for the earbud case itself.
• BOVUGAC Case — biggest strength: a soft silicone shell with keychain, lanyard and a cleaning pen that keeps a JBL Tune 120 / Tune T125 charging case safe and clipped to your bag.
• BOVUGAC Case — biggest trade-off: it is a cover only, so it adds nothing to sound, fit or battery performance, and it fits no other earbuds.
• Buy TENNMAK Replacement Dust Proof if your existing Sony or Edifier earbuds feel muffled or loose and you want to fix them instead of replacing them.
• Buy BOVUGAC Case if you already own JBL Tune 120 TWS or Tune T125 TWS and want cheap, practical protection plus a way to stop losing the case.
This is a repair kit, not a product you buy for a new pair of earbuds. TENNMAK sells ten pairs of replacement mesh in total: five pairs in nylon and five pairs in metal, plus a pair of tweezers to do the swap. The enclosure material is listed as metal and nylon, and the pieces are tiny — the whole set measures 5.91 x 3.94 x 0.08 inches, so it arrives as a flat sheet of nearly weightless parts. The color is black and gold, which is purely cosmetic here; nobody sees a dust filter once it is seated.
The job it does is simple and genuinely useful. Dust mesh sits between the nozzle and your ear, and over months it collects wax, lint and skin oil until the sound turns dull and the bass disappears. TENNMAK's process is a three-step one: lift the old mesh off with the tweezers and clean the earbud tube, pick up a fresh mesh with the same tweezers, then press it onto the tube and hold it down a few times so it sticks. That is the entire job, and it takes minutes per earbud.
BOVUGAC Case: Who It's For
This is a protective cover built specifically for the JBL Tune 120 TWS and JBL Tune T125 TWS true wireless earbuds. The manufacturer states plainly that it is not compatible with other devices, so this is a one-model accessory. It is made of soft silicone in green with a nature-style pattern, and the whole point is that it is skin-friendly, silky in the hand, and adds protection without adding bulk. Scratches, accidental drops, shocks and bumps are the things it is designed to absorb.
The package is more generous than the price-point category usually offers: one silicone case cover, one carabiner keychain, one cleaning pen and one lanyard. The keychain clips to a handbag, backpack or computer backpack, and the lanyard gives you a second way to hang it. Together they attack the single most common way people lose cheap TWS earbuds — leaving the charging case on a table or in a pocket and never seeing it again. The cleaning pen is a small but sensible addition, since the same dust and wax problems that plague every TWS earbud will eventually reach a JBL Tune as well.
Who should buy it? JBL Tune 120 or Tune T125 owners who carry their earbuds daily, students and commuters who toss a case into a bag, and anyone who has already lost one charging case and does not want to repeat the experience. Who should skip it? Owners of any other earbud brand, and anyone hoping for a sound upgrade. The earbuds themselves are not included, and the case changes nothing about how the JBL Tune sounds.
Side-by-Side: Which Should You Choose?
• Best for protecting a JBL Tune 120 / Tune T125 → BOVUGAC Case. The silicone shell and keychain are purpose-built for those two models and nothing else.
• Best for carrying convenience → BOVUGAC Case. A carabiner keychain plus a lanyard gives you two attachment options; the TENNMAK kit just lives in a drawer until you need it.
• Best for long-term ownership → TENNMAK Replacement Dust Proof. Ten pairs of mesh means you can repeat the fix many times over instead of buying new earbuds.
• Best for a gift or stocking filler → BOVUGAC Case. A complete kit with a cleaning pen and lanyard feels like a finished present; a bag of tiny filters does not.
• Best for Edifier TWS NB2 / NB2 Pro owners → TENNMAK Replacement Dust Proof. The BOVUGAC case will not fit Edifier earbuds at all.
• Best for Sony WF-1000XM3 / XM4 owners → TENNMAK Replacement Dust Proof. Same logic: match the accessory to the model you actually own.
In my opinion, TENNMAK Replacement Dust Proof is the smarter buy for most people reading this, because it fixes a real, inevitable problem on earbuds that are otherwise still good — and it works across four popular Sony and Edifier models. I would pick the BOVUGAC Case only if you specifically own JBL Tune 120 TWS or Tune T125 TWS and your priority is keeping that charging case alive and attached to your bag. Neither one improves sound quality on its own; one restores it, the other protects your hardware. Decide which of those two problems is actually yours, and the choice makes itself.
