How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a cheap, high-count supply of replacement silicone tips that keeps your JBL Endurance earbuds fitting and sealing like they should, choose Klowcok Ear Tips; if you need a complete set of splashproof wireless earbuds with a charging case and touch controls, choose QFX Splashproof.
• Klowcok Ear Tips — biggest strength: 12 pairs of soft silicone tips in three sizes (S/M/L), with 9 pairs in black and 3 in red, so you can re-seal a whole drawer of JBL Endurance buds without buying new earphones.
• Klowcok Ear Tips — biggest trade-off: They are tips only. No earbuds, no cable, no case — if your actual earphones are dead, these fix nothing.
• QFX Splashproof — biggest strength: A full TWS earbud system: Bluetooth 5.3, 10mm dynamic drivers, touch controls, USB-C charging and a splashproof LED case that shows battery level.
• QFX Splashproof — biggest trade-off: Earbud play time is listed at up to 3 hours, which is short by modern standards, and the case is what carries the extra runtime.
• Who Klowcok is for: JBL Endurance Run 2 / Peak 3 / Peak II / Race owners whose tips are worn, torn or lost.
• Who QFX is for: Anyone who wants a self-contained pair of wireless earbuds for workouts, commutes and calls — and doesn't already own a compatible set.
Klowcok Ear Tips are a maintenance part, not a gadget. You get 24 individual silicone tips — 12 pairs — split across small, medium and large, with four pairs of each size. Nine pairs are black and three are red, which is a small thing but genuinely useful: it lets you mark one side, or just keep a color-coded spare set in your bag without hunting for a matching pair.
The material is soft, lightweight silicone, and the pitch is straightforward: easy to swap on, secure once seated, and effective at blocking outside noise. That last point matters more than people expect. A silicone tip that actually seals your ear canal is most of what "noise isolation" means on any in-ear bud — you don't get that from a tip that's the wrong size or has gone slick and loose. If your current tips keep slipping out mid-run or you've been jamming the medium size in when your ears really want the small, this is the fix.
Compatibility is the whole story here. Klowcok lists these for the JBL Endurance Peak 3, JBL Endurance RACE and JBL Endurance Run 2. If that's your earphone, this is a sensible, low-drama purchase — buy it, replace the tips, keep using the buds you already like. The tips are washable, so a rinse brings them back rather than sending you shopping again.
QFX Splashproof: Who It's For
The QFX Splashproof (model HP-E110) is the opposite kind of product: a complete wireless earbud package. Inside the box you get the TWS earbuds, a charging case, and three sets of soft gel inserts in small, medium and large. Nothing else is required to start listening.
The spec sheet is a solid mid-tier wireless recipe. Bluetooth 5.3 covers pairing and connection stability, with lower power draw and extended range versus older Bluetooth versions. The drivers are 10mm dynamic units, tuned — per QFX — for punchy bass with detailed mids and highs, which is the profile most people want for music, calls and video. Controls are touch-based, so you tap the bud to manage playback and phone calls instead of reaching for your phone.
Two features stand out for real-world use. First, the charging case has a digital LED display that shows battery level, so you're not guessing whether you have enough charge left before a workout. Second, the whole setup is described as IPX4 sweat- and splashproof, and the case charges over USB-C for faster top-ups. The case itself holds a 300mAh battery and the buds have 30mAh cells each, with play time listed at up to 3 hours.
That 3-hour figure is the honest catch, and it's the number I'd weigh hardest. Three hours per charge is fine for a gym session, a commute or a run, and the case extends total listening time between wall charges. It is not a pair you'd wear for a full workday of continuous audio without docking them back in the case. If you're a heavy all-day listener, be realistic about that. If you're a short-session user — workouts, walks, calls in the car — it lines up well.
Who should buy it? Someone who wants one purchase that covers earbuds, charging and fit adjustment, and who values the LED battery readout and USB-C convenience. Who should skip it? Anyone who needs marathon battery per charge, or who already owns compatible JBL Endurance buds and only needs fresh tips.
• You already own JBL Endurance Run 2, Peak 3, Peak II or Race → Klowcok Ear Tips. It's the exact job these were made for.
• You need actual earbuds, not parts → QFX Splashproof. Klowcok ships tips only and explicitly does not include earbuds.
• Best for fit tuning across multiple ear sizes → Klowcok Ear Tips. Twelve pairs, four per size, in two colors.
• Best for a self-contained wireless setup → QFX Splashproof. Bluetooth 5.3, touch controls, charging case, USB-C.
• Best for long listening sessions per charge → QFX Splashproof, with a caveat. Up to 3 hours per charge, extended by the case — plan around it.
• Best for sweat and splash exposure → QFX Splashproof. The IPX4 rating covers sweat and splashes; Klowcok tips are washable silicone but are a passive part.
• Best for battery visibility → QFX Splashproof. The LED display on the case shows charge level directly.
• Best for keeping a favorite pair of earphones alive → Klowcok Ear Tips. New tips, same buds, no re-pairing, no new charger.
In my opinion, these two don't really compete — they solve different problems, and the right answer depends entirely on what's in your pocket right now. If you own JBL Endurance Run 2, Peak 3 or Race earbuds that still sound good but won't stay put, I'd buy the Klowcok Ear Tips. Twelve pairs of washable silicone in three sizes is the cheapest way to restore a seal you already liked.
If you need earbuds, I'd buy the QFX Splashproof. Bluetooth 5.3, 10mm drivers, touch controls, USB-C and an LED case make it a complete, tidy package — just go in knowing the listed play time is up to 3 hours per charge.
No. It's 12 pairs of silicone tips only — 9 black, 3 red, in S/M/L — and the packaging does not include earbuds. It's a replacement part for compatible JBL Endurance models.
Yes. The box includes three sets of soft gel inserts in small, medium and large, alongside the earbuds and the charging case.
QFX lists play time at up to 3 hours. The charging case has its own 300mAh battery and an LED display showing battery level, so you can top the buds up between sessions.
The Klowcok tips. Fit problems on in-ear buds are almost always a tip-size or tip-condition issue, and you get four pairs each of small, medium and large to find the seal that holds. Check the current price on Amazon before deciding.
