How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a lightweight, semi in-ear wired earbud for school, PC work and long desk sessions with full in-line volume control, choose ASKUBSKU 3.5mm; if you need a sweat-proof, secure-fit sport headphone for running and hard workouts in any weather, choose JBL Endurance Run 3.
• ASKUBSKU 3.5mm — biggest strength: its 45° angled semi in-ear shape is built to avoid ear pressure and stay put without jamming deep into the canal, plus it gives you a complete in-line remote with volume, playback and call buttons.
• ASKUBSKU 3.5mm — biggest trade-off: it carries no water or dust resistance rating, so sweat and rain are real risks, and its semi in-ear fit lets in more outside noise than a sealing sport bud.
• JBL Endurance Run 3 — biggest strength: IP65 dustproof and water-resistant build with TwistLock secure fit and FlipHook two-way wearing (in-ear or behind-the-ear) for high-intensity training.
• JBL Endurance Run 3 — biggest trade-off: the in-line remote is a single button with no dedicated volume keys, so you'll adjust loudness on the phone itself.
• Pick ASKUBSKU 3.5mm if you want comfortable all-day earbuds for study, calls and computer use at a budget-friendly entry point.
• Pick JBL Endurance Run 3 if you're buying specifically for sport, sweat and weather, and want a brand-name audio driver with a secure lock-in fit.
The ASKUBSKU 3.5mm is a wired, 3.5 mm jack earbud with a Dynamic Driver covering 20 Hz – 20,000 Hz, housed in an angled semi in-ear shell made from ABS and TPE. That combination sounds unremarkable on paper, but the design intent is clear: it's an earphone for people who wear buds for hours and hate the stuffed, pressurized feeling of a deep-sealing tip. The 45° insertion angle is meant to sit at the edge of the ear canal rather than plug it, and the listing explicitly frames it as "no ear pressure feeling" and "no pain in ears after long time wear." For a student on a laptop all afternoon or someone on back-to-back video calls, that's the whole point.
Who should skip it? Anyone whose priority is sweat, rain or gym abuse. There's no IP rating here, so heavy perspiration, downpours or a water bottle mishap could end the relationship early. And because it's a semi in-ear design, it won't block much ambient noise — fine for a quiet library, less fine on a noisy train. It comes in Pink with a matching flat-free plastic/rubber case, one item per package.
JBL Endurance Run 3: Who It's For
The JBL Endurance Run 3 is a wired sport headphone with one job: stay in your ears and survive your training. Its 8 mm Dynamic Driver is tuned for JBL Pure Bass Sound, and the whole shell is built from soft silicone-style material with the company's TwistLock fit system, which the brand describes as lightweight and ergonomically shaped to keep the buds sealed and stable no matter the workout. At 16.8 g, it's light enough that you stop noticing it, which matters when you're moving.
The standout design feature is FlipHook. The flexible two-way hook lets you wear the headphone either in-ear or behind-the-ear — a genuinely useful option if one style slips during sprints or burpees but the other holds. Then there's the IP65 rating: dustproof and water-resistant, which the listing ties directly to high-intensity indoor and outdoor sessions in any weather. That single spec is what separates it from a general-purpose earbud. If you sweat heavily or run in the rain, this is the category of product you want.
The controls are simpler than the ASKUBSKU's. There's a one-button in-line remote with a microphone for hands-free calls, and a long press wakes your phone's native Voice Assistant — the sheet names Google Assistant and Siri. You get call handling and assistant access, but volume lives on your phone. JBL bundles three sizes of ear tips plus an "Enhancer," and the package includes a one-year manufacturer warranty. Magnetic buds keep the cable tidy around your neck between sets. The trade-off versus the ASKUBSKU is straightforward: fewer on-wire controls and a more sport-focused fit that some people find firmer than a casual semi in-ear.
• Best for workouts and running → JBL Endurance Run 3. IP65 plus TwistLock and FlipHook are purpose-built for sweat and movement.
• Best for long desk, study and call sessions → ASKUBSKU 3.5mm. The semi in-ear angle is designed to avoid pressure over long wear.
• Best on-wire controls → ASKUBSKU 3.5mm. Volume, playback, calls, assistant and camera shutter from the cable; the JBL gives you one button.
• Best weather and sweat resistance → JBL Endurance Run 3. No contest — the ASKUBSKU has no IP rating.
• Best for noisy environments → JBL Endurance Run 3. Its sealing sport tips isolate more than the ASKUBSKU's semi in-ear fit.
• Best for Switch, MP3, Kindle and older 3.5 mm gear → ASKUBSKU 3.5mm. Wired, plug-and-play, and explicitly listed for those devices.
• Best brand-name audio tuning for bass → JBL Endurance Run 3. An 8 mm Pure Bass driver with a 1-year warranty behind it.
• Best for shared or around-the-neck convenience → either. Both use magnetic buds so the cable hangs neatly when not in use.
If I were buying for myself and my priority was showing up to the gym, sweating hard and running outdoors, I'd take the JBL Endurance Run 3. The IP65 rating, TwistLock fit and FlipHook two-way wearing solve the two problems that actually ruin sport headphones: slipping and moisture. If instead my day is classes, calls and a laptop, I'd take the ASKUBSKU 3.5mm — its pressure-free semi in-ear shape and full in-line controls are better suited to hours of stationary use, and I'd just keep it away from heavy sweat. Match the tool to the job; that's the whole decision.
FAQ
Yes, in my opinion. The JBL carries an IP65 dustproof and water-resistant rating plus TwistLock and FlipHook secure-fit tech, while the ASKUBSKU has no water or dust rating at all. For running and sweaty training, the JBL is the safer pick.
Yes. Its in-line remote handles volume up/down, play/pause, answer/hang up, voice assistant and camera shutter. The JBL Endurance Run 3 uses a single-button remote, so volume is adjusted on your phone instead.
I don't quote prices here, and neither product's data sheet includes pricing. Check the current price on Amazon using the button on this page and compare both listings directly before you decide.
Both have an in-line microphone. The ASKUBSKU emphasizes a high-sensitivity mic with enhanced voice for clearer calls, while the JBL offers hands-free calling with a long-press Voice Assistant shortcut. Either works; the ASKUBSKU's extra on-cable controls make it more convenient for desk and classroom use.
There's no IP rating in its data sheet, so I wouldn't count on it. Keep it for dry, stationary use and choose the IP65-rated JBL Endurance Run 3 if moisture and sweat are part of your routine.
