If you want a cheap way to restore the fit, seal and bass of the JBL TUNE120, TUNE125 or T120 earbuds you already own, choose Sqrmekoko 3; if you need a compact, protective home for your JBL Endurance Peak 3, Peak 2 or Peak earbuds and their charging case, choose Alltravel TWS Earbuds Case. These are two very different accessories for the same general world of cheap TWS earbuds, and neither one is a pair of earbuds — that's the first thing to get straight before you buy. For office use, the split is simple: Sqrmekoko keeps the buds you already wear at your desk comfortable and sealed, while Alltravel keeps them protected in a bag or drawer when you're not wearing them.
• Sqrmekoko 3 — biggest strength: A 6-piece set (3 pairs) of soft, skin-friendly silicone eartips specifically shaped for JBL TUNE120, TUNE125 and T120 TWS earbuds, with a sealed design that helps block outside noise and lift bass.
• Sqrmekoko 3 — biggest trade-off: It only fits those JBL models, and it's an eartip replacement — it does nothing for your charging case or cable.
• Alltravel TWS Earbuds Case — biggest strength: A palm-size, semi-hard carrying case in PEVA with a matching elastic strap and a mesh pocket, so your earbuds, charging case and cord stay together and protected.
• Alltravel TWS Earbuds Case — biggest trade-off: It's the case only — the earbuds and accessories are sold separately — and it's built around the JBL Endurance Peak family, not the TUNE line.
• Who each pick is for: Sqrmekoko 3 is for someone whose JBL TUNE earbuds fit badly or whose tips are lost or worn out. Alltravel is for someone who already owns Endurance Peak earbuds and wants them organized, cushioned and easy to carry.
Sqrmekoko 3 is a replacement eartip kit, and it's honest about that. You get 6 silicone eargels — three pairs — made from a high-grade, skin-friendly silicone that's soft and flexible rather than stiff and plasticky. The point of that softness is long sessions: if you wear earbuds through a workday, at a desk, on calls or through a commute, the material matters more than most people expect. Hard, tired silicone gets uncomfortable fast; this is designed to stay gentle.
Who should buy it: anyone with JBL TUNE120, TUNE125 or T120 earbuds who wants a snug, secure fit that holds during workouts, travel or daily wear, and who wants spares on hand. Who should skip it: anyone with a different earbud brand or model, and anyone hoping this fixes their charging case or cable situation — it won't. It's eartips, and only eartips. There's a 12-month warranty listed, which is a reasonable cushion for a small silicone part.
Alltravel TWS Earbuds Case: Who It's For
Alltravel TWS Earbuds Case is the other half of the equation: protection and organization. It's a palm-size, compact, lightweight carry case at roughly 4.5 x 3.25 x 1.5 inches and 1.8 ounces, so it disappears into a backpack pocket or a desk drawer without bulk. The exterior is a semi-hard PEVA shell with a white striped finish, described as water resistant and built to absorb pressure and knocks — the kind of semi-hard protection that stops a charging case from getting crushed or scuffed at the bottom of a bag.
Inside, the design is practical rather than fancy. A matching-size base with an elastic strap holds the device firmly so it doesn't rattle around, and a mesh pocket takes the charging cord and small accessories so they don't scratch the case or tangle into a knot. There's a carabiner included, which is the detail that makes it genuinely carry-friendly: clip it to a bag strap or a belt loop and it's out of the way but always with you. It's aimed at JBL Endurance Peak 3, Peak 2 and Peak True Wireless earbuds, and it's meant to hold the earbuds' own charging case, the cord and the small extras together.
Who should buy it: JBL Endurance Peak owners who move around a lot — gym bag, commute, travel, or just a tidy drawer at home — and who are tired of hunting for a loose charging case and cable. Who should skip it: anyone with JBL TUNE earbuds (wrong fit family), and anyone who thinks they're getting earbuds in the box. They aren't — it's the protective case only, device and accessories sold separately. It carries a 1-year warranty.
Side-by-Side: Which Should You Choose?
• Best for a snug, secure fit during workouts or travel → Sqrmekoko 3. The sealed design grips the nozzle and stays put.
• Best for improving noise isolation and bass on cheap TWS earbuds → Sqrmekoko 3. A proper seal does more for sound than most tweaks.
• Best for keeping earbuds, charging case and cord together → Alltravel. Elastic strap plus mesh pocket, all in one place.
• Best for throwing in a bag or clipping to a strap → Alltravel. Palm-size, 1.8 ounces, with a carabiner.
• Best for shock, scratch and light water resistance → Alltravel. Semi-hard PEVA shell described as water resistant.
• Best for office desk duty → either, depending on the problem. Sqrmekoko if your TUNE buds hurt or won't seal through a long day; Alltravel if your Endurance Peak kit needs a tidy, protected home between sessions.
• Best if you want a spare-parts safety net → Sqrmekoko 3. Six pieces means backups, not a single replacement.
In my opinion, if you're dealing with fit, comfort or seal problems on JBL TUNE120, TUNE125 or T120 earbuds, Sqrmekoko 3 is the smarter buy — it directly addresses the thing that makes cheap TWS earbuds pleasant or miserable, and you get three pairs. It's also the one that matters most for office use, where you're wearing buds for hours and a bad seal ruins both sound and comfort. I'd only point you to the Alltravel TWS Earbuds Case if you own JBL Endurance Peak earbuds and your real problem is storage and protection, not sound. Different problems, different fixes — buy for the problem you actually have, and check the current price on Amazon before you commit.
FAQ
TWS stands for "true wireless stereo" — earbuds that connect to your phone or laptop with no wire between the two buds. Both products on this page are accessories for TWS earbuds, not earbuds themselves: Sqrmekoko 3 is a set of replacement silicone eartips, and Alltravel is a protective carrying case.
It means the left and right earbuds connect wirelessly to each other and to your device, with no cable joining them. That's why accessories like eartips and cases matter so much with cheap TWS earbuds — the buds are small and easy to lose, and the fit depends entirely on the tips you're using.
I can't quote prices here, and the cost varies by brand and model. What matters more is matching the accessory to your earbuds: Sqrmekoko 3 fits JBL TUNE120, TUNE125 and T120, while Alltravel fits JBL Endurance Peak 3, Peak 2 and Peak. Check the current price on Amazon for the exact figure.
Start with the tips. If your JBL TUNE buds feel loose, fall out, or sound thin, replacement silicone eartips like Sqrmekoko 3 restore the seal, which improves noise isolation and bass. For storage and travel, a compact case like the Alltravel keeps the charging case, cord and extras protected and organized so nothing gets lost.
