How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want an open-ear design that keeps your ear canals completely open while you run, ride or train in heavy sweat and rain, choose QXUFV Open Ear Headphones; if you need a compact in-ear pair with cute Miffy styling, active noise cancellation and fast charging for sweaty gym sessions, choose MIPOW x Miffy Miffy.
• QXUFV Open Ear Headphones — biggest strength: a true open-ear fit (9.5g) plus an IPX7 waterproof rating and 50 hours of total playtime, which makes it the more forgiving pick for sweaty, long outdoor sessions.
• QXUFV Open Ear Headphones — biggest trade-off: open-ear means no active noise cancellation, just passive isolation, so loud environments stay loud. Its silicone-wrapped design is also bulkier than a tiny in-ear bud.
• MIPOW x Miffy Miffy — biggest strength: a genuinely fun 4g in-ear bud with Bluetooth 5.3, active noise cancellation, IPX5 sweat resistance and a 3D iron box with a Miffy doll that doubles as packaging you'll want to keep.
• MIPOW x Miffy Miffy — biggest trade-off: IPX5 handles sweat and splashes but not immersion, and 6 hours per charge (30 with the case) is far less endurance than the QXUFV.
• Who each pick is for: the QXUFV suits runners, cyclists and marathon-length training days who want to hear traffic; the MIPOW suits gym-goers and casual listeners who want a cute, pocketable, noise-cancelling bud.
The QXUFV is built around one idea: keep your ears open. The earbuds rest around your ear rather than inside it, and at 9.5g with liquid silicone rubber construction, the design intent is all-day comfort without ear fatigue. For anyone who has quit on earbuds because their canals ache after an hour, that's the whole pitch. You also keep full situational awareness, which matters if you run or cycle anywhere near traffic — you hear the music and the car behind you at the same time.
The spec sheet backs up the sweatproof angle hard. IPX7 is the standout number here: that rating covers sweat, rain and even accidental immersion, which is well beyond what most sports buds claim. Pair that with 50 hours of total playtime (up to 10 hours per earbud) and a charging case with an LED power display, and you have a setup that survives a week of training without a wall outlet. Bluetooth 5.4 gives you a 15-meter range, instant reconnection after the first pairing, and touch controls for play/pause, volume, tracks, calls and your voice assistant.
Sound comes from 14.2mm dynamic drivers covering 20Hz–20,000Hz, tuned for punchy bass to keep workouts moving, with HD mic clarity for calls. The trade-off is honest: passive noise cancellation only. You will hear the gym, the wind and the road. If you want to block the world out, this is the wrong design. The 24-month repair support is a nice long-term signal, and the red finish is a bold look rather than a subtle one. In my opinion, this is the pick for outdoor athletes and anyone who values awareness over isolation.
The MIPOW x Miffy is the opposite philosophy — small, sealed and stylish. Each bud weighs just 4g and sits in the ear with an ergonomic contour that the design targets for stable, pain-free long wear. Because it's a proper in-ear fit, it also supports active noise cancellation, which the open-ear QXUFV simply cannot offer. If your training happens in a noisy gym or on a loud commute, that's a real functional difference, not just a marketing line.
Sweatproofing is rated IPX5, which the brand explicitly frames around resistance to sweat and water splashes — rain and gym sweat are fine, but don't plan on swimming or rinsing them under a tap. Battery is 6 hours per single charge and 30 hours total with the case, topped up by 1-hour USB-C fast charging. That's a short single-session figure; for a 45-minute gym visit it's plenty, for a full day of hiking it isn't.
Side-by-Side: Which Should You Choose?
• Best for heavy sweat and rain → QXUFV Open Ear Headphones. IPX7 beats IPX5 on water resistance, and that gap matters if you train outdoors in all weather.
• Best for battery life → QXUFV Open Ear Headphones. 50 hours total and up to 10 hours per earbud versus 6 hours per charge and 30 total on the MIPOW.
• Best for noise cancellation → MIPOW x Miffy Miffy. Active noise cancellation versus passive isolation on the QXUFV.
• Best for situational awareness and road safety → QXUFV Open Ear Headphones. The open-ear design lets ambient sound in by default.
• Best for all-day comfort without ear-canal pressure → QXUFV Open Ear Headphones. 9.5g open-ear fit with no insertion, though the MIPOW's 4g in-ear build is lighter on paper.
• Best for fast top-ups → MIPOW x Miffy Miffy. A 1-hour USB-C charge for the case is quicker than the QXUFV's charging cycle.
• Best for a fun, giftable design → MIPOW x Miffy Miffy. The Miffy doll, LED-lit case and 3D iron box are the entire point.
• Best for the newest Bluetooth standard → QXUFV Open Ear Headphones. Bluetooth 5.4 with a 15-meter range versus Bluetooth 5.3.
If I were buying for sweat-heavy sport, I'd take the QXUFV Open Ear Headphones. IPX7 plus 50 hours of playtime plus an open-ear fit that keeps you aware of your surroundings is exactly the combination a runner or cyclist needs, and the 24-month repair support sweetens it. I'd only steer myself to the MIPOW x Miffy Miffy if noise cancellation, a tiny 4g bud and that Miffy design mattered more to me than endurance and waterproofing — which, for indoor gym sessions, is a completely reasonable trade.
what are sports earbuds
Sports earbuds are wireless earbuds designed to stay put and survive sweat during movement. Both picks here qualify in different ways: the QXUFV uses an open-ear 9.5g hook-style fit with IPX7 waterproofing, while the MIPOW x Miffy uses a 4g in-ear fit with IPX5 sweat and splash resistance.
how to wear sports earbuds
The QXUFV rests around the outside of your ear, leaving the canal open — no insertion needed. The MIPOW x Miffy sits inside the ear, so you seat each 4g bud against your ear contour for a snug, stable fit. In both cases, a secure fit is what keeps them in during a run.
how to connect sports earbuds
Both are Bluetooth-only with no headphone jack. Power them on and pair once from your phone, tablet or PC — the QXUFV runs Bluetooth 5.4 with a 15-meter range and auto-reconnects when you take it out of the case, while the MIPOW x Miffy uses Bluetooth 5.3 with instant pairing across iPhone, Samsung, Android, PC and most wireless players.
how to use sports earbuds
Both use touch controls. On the QXUFV you tap to play/pause, adjust volume, switch tracks, take calls and trigger your voice assistant. The MIPOW x Miffy covers play/pause, track skipping, call answer/end and Siri or Google Assistant. Check the current price on Amazon before deciding, since value depends on what you're paying at the time.
