How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want one pair of earbuds to cover translation, a smart touchscreen case and deep, adjustable bass for running, choose QXUFV Earbuds; if you need earbuds that simply will not budge mid-sprint, choose Jesebang Earbuds. That's the short version. The longer version comes down to what you actually do with earbuds when your heart rate is up — and how much you care about bass depth versus a locked-in fit.
• QXUFV Earbuds — biggest strength: a genuinely unusual feature set. Real-time translation across 164 languages, five EQ modes, ANC plus transparency, and a touchscreen charging case that does far more than charge.
• QXUFV Earbuds — biggest trade-off: the in-ear, no-hook design. Nothing in the spec sheet promises it stays put through hard sprint intervals, and the battery is rated lower per charge.
• Jesebang Earbuds — biggest strength: a sport-first build. Flexible earhooks, 7g per bud, three eartip sizes, IPX7 waterproofing and 14.2mm drivers tuned for bass.
• Jesebang Earbuds — biggest trade-off: it's a focused workout tool. No translation, no screen on the case, no transparency mode listed.
• Who each is for: QXUFV for the runner who wants one pair to do everything — music, calls, travel, language. Jesebang for the runner who wants the earbuds to disappear and stay put.
The QXUFV U9 is the more ambitious product of the two. The 13mm graphene driver with a triple-layer composite membrane is built to push bass down to 50Hz, and the five EQ modes — Standard, Classic, Jazz, Rock, Pop — let you reshape that low end depending on what you're playing. For running, the Rock and Pop settings are the obvious starting points if you want that thump under your stride. This is the "bluetooth headphones deep bass" angle done with some flexibility, rather than one fixed tuning.
Then there's the stuff you won't find on most earbuds. The charging case has a touchscreen, and it handles things you'd normally reach for your phone to do: set a timer, adjust brightness, change language, trigger the camera, even set a wallpaper. The case also helps you locate the buds if you misplace them. On top of that, the U9 does real-time translation across 164 languages with seven translation modes — aimed at travel, cross-border calls and language learning. Bluetooth 5.4 keeps the connection stable up to 15 meters, ANC handles ambient noise, and transparency mode pipes the outside world back in so you can hear traffic while you run or ride.
Battery is the honest weak point. QXUFV rates it at 6–8 hours per charge with a 1.5-hour charge time, and the case adds five more charges for 48 hours total. That's plenty for a week of runs and commutes, but it trails the Jesebang figure. Buy the QXUFV if you want a single pair that handles music, calls, translation and daily life, and you're comfortable with an in-ear fit. Skip it if your priority is a fit that ignores violent head movement, or if you want the longest possible battery per charge.
The Jesebang S75 is built around one question: will these stay in while I move? The answer, based on the design, is yes. Soft elastic earhooks lock the buds against your ear, and Jesebang explicitly designs them not to slip during running or jump rope. Each bud weighs just 7g, and you get three sizes of eartips, so you can dial in the seal rather than accepting whatever the factory shipped. For a runner, that combination — hook plus correct tip size — is the difference between a good run and constantly re-seating a bud at a crosswalk.
Sound leans bass-forward too, but differently. The 14.2mm dynamic drivers are the largest single number in either spec sheet, and Jesebang tunes them for strong bass with clear mids and bright highs. It's one fixed signature rather than five EQ presets, so you either like it or you don't — but for workout music, a big driver with a strong low end is exactly the right call. The ENC microphone array claims to cut up to 80% of background noise on calls, which matters if you take work calls from a noisy street.
Battery is the standout number: up to 10 hours per charge, 50 hours total with the case, and a dual LED display on the case and buds so you can see the level at a glance. IPX7 waterproofing covers sweat and rain. Bluetooth 5.4, 15-meter range, auto-reconnect on opening the case, and touch controls for playback, volume, calls and voice assistants round it out. Buy the Jesebang if you run, jump, or sweat hard and want the fit and battery to be non-issues. Skip it if you want translation, a smart case, or adjustable EQ — none of that is here.
• Best for running fit → Jesebang Earbuds. Earhooks, 7g buds and three eartip sizes are purpose-built for movement.
• Best for deep bass flexibility → QXUFV Earbuds. 50Hz bass extension with five EQ modes beats one fixed tuning for tailoring sound.
• Best for battery per charge → Jesebang Earbuds. 10 hours versus 6–8 hours.
• Best total battery → Jesebang Earbuds. 50 hours versus 48 hours.
• Best for calls in loud places → Jesebang Earbuds. ENC rated to cut up to 80% of background noise.
• Best for travel and language → QXUFV Earbuds. 164 languages, seven translation modes, nothing comparable on the Jesebang.
• Best for safety while running near traffic → QXUFV Earbuds. Transparency mode is listed; the Jesebang sheet doesn't mention one.
• Best touch control headset for running → Jesebang Earbuds. Touch control plus a hook fit means you can adjust without stopping; the QXUFV's case screen is a nice extra but you won't use it mid-run.
• Best all-rounder → QXUFV Earbuds. More features, wider use cases, at the cost of a less sport-specific fit.
In my opinion, if running is the main event, I'd buy the Jesebang Earbuds. Earhooks, 7g per bud, IPX7 and 10 hours per charge are the four things that actually decide whether a run goes well, and the S75 nails all four. I'd pick the QXUFV Earbuds instead if running is only part of the picture — the translation, EQ modes, transparency and touchscreen case make it the better everyday companion, and 48 hours total is still generous. If you're torn, decide which matters more: staying in your ears, or doing more things. Either way, check the current price on Amazon before you commit — it's the one variable that can tip a close call.
For pure running, I'd lean Jesebang. The earhook design, 7g weight and three eartip sizes are specifically built to stop slippage during intense exercise. The QXUFV is a capable in-ear pair, but nothing in its specs targets high-movement fit the way the S75 does.
Which has better bass, QXUFV or Jesebang?
Both go deep, in different ways. QXUFV uses a 13mm graphene driver reaching down to 50Hz and gives you five EQ modes to shape it. Jesebang uses a larger 14.2mm driver with a fixed bass-forward tuning. If you want to adjust bass per song, QXUFV; if you want it baked in, Jesebang.
They have an ENC noise-cancelling microphone rated to remove up to 80% of background noise on calls — that's call clarity, not active noise cancelling for your music. The QXUFV, by contrast, lists full ANC plus a transparency mode.
Jesebang: up to 10 hours per charge, 50 hours with the case. QXUFV: 6–8 hours per charge, 48 hours total, with a 1.5-hour charge time. Jesebang leads on both single-charge and total playback.
