How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a rotatable, hybrid open-ear design that can shift between music focus and full world awareness, choose JBL Soundgear Sense; if you need marathon battery life, Hi-Res LDAC audio, and true IPX7 waterproofing, choose EarFun OpenJump Open Ear.
• JBL Soundgear Sense — biggest strength: rotating earhooks plus a detachable neckband give you the only genuinely hybrid fit here, and JBL OpenSound Tech aims sound at your ears to keep leakage down.
• JBL Soundgear Sense — biggest trade-off: 6 hours per charge (24 total with the case) and IP54 splash resistance, so it's more of a daily-life and light-workout pick than a swim-or-downpour pick.
• EarFun OpenJump Open Ear — biggest strength: up to 11 hours per bud and 42 hours with the case, LDAC Hi-Res audio through a 14.2mm wool composite driver, IPX7 waterproofing, and four mics with AI noise reduction on calls.
• EarFun OpenJump Open Ear — biggest trade-off: the earhook is fixed rather than rotatable, and there's no neckband or wireless charging case in the box.
• Who the JBL is for: people who want one pair for the office, commute, and light training, and who like the idea of physically repositioning the buds depending on the situation.
• Who the EarFun is for: runners, gym-goers, and long-shift workers who want the battery to outlast the day and don't mind charging by cable.
The Soundgear Sense is built around JBL's OpenSound Technology, an air-conduction approach that funnels sound waves toward your ears rather than blasting them into open air. The practical promise is less sound leaking out and more of it landing where you want it — while your ears stay completely uncovered so you can still hear traffic, a colleague, or a flight announcement. Each earbud carries a 16.2mm dynamic driver paired with a bass-enhancing algorithm, and the frequency response runs 20 Hz to 20 kHz at 32 ohms with 112 dB sensitivity.
Buy the JBL if you want a single pair that moves with your day — desk work, calls, a commute, and a jog — and you value being able to reposition the buds rather than accept one fixed angle. Skip it if you're a heavy sweater, run in the rain, or routinely go days between charges; the IP54 rating and 6-hour single-charge figure are the honest limits here. If price matters to you, check the current price on Amazon before deciding.
EarFun OpenJump Open Ear: Who It's For
The OpenJump takes the opposite approach: instead of adjustability, it leans hard into endurance, audio codecs, and weatherproofing. The 14.2mm wool composite driver is larger in diameter than the JBL's 16.2mm? No — it's smaller in diameter, but it's paired with LDAC and Hi-Res audio support plus EarFun's BassSurge tuning, which targets deep bass and crisp treble. LDAC matters if you stream from a compatible Android device and want more data moving over Bluetooth; it's a codec advantage the JBL spec sheet doesn't claim.
Battery is the headline. EarFun rates the OpenJump at up to 11 hours per charge and 42 hours total with the case — nearly double the JBL's single-charge figure and well past its case total. A 10-minute charge returns 2 hours of playback. The rating is IPX7 with SweatShield, which means it's built for sweat, rain, and splashes rather than just tolerating them, and each earbud weighs about 0.28 oz (the full package, including case and cable, is listed at 72.4 g). Four beamforming mics with AI processing handle calls, and Bluetooth 5.3 supports multipoint so you can stay connected to two devices at once, plus Google Fast Pair for quick Android setup. The double-curved earhook is soft and adjustable for a snug fit, though it doesn't rotate the way JBL's does.
Buy the EarFun if your priority is long sessions, workouts, and outdoor weather — the battery and IPX7 rating are the reasons. Skip it if you want a neckband for extra security, wireless charging, or a fit you can re-angle on the fly. As with any of these, check the current price on Amazon rather than assuming.
Side-by-Side: Which Should You Choose?
• Best for heavy sweat and rain → EarFun OpenJump Open Ear: IPX7 waterproofing beats the JBL's IP54 splash rating.
• Best audio codec support → EarFun OpenJump Open Ear: LDAC and Hi-Res audio are on the spec sheet; the JBL lists Bluetooth 5.3 but no Hi-Res codec.
• Best call clarity setup → EarFun OpenJump Open Ear: four beamforming mics with AI noise reduction, versus the JBL's emphasis on voice pickup that stays audible in wind.
• Best fit flexibility → JBL Soundgear Sense: rotating earhooks plus an included neckband give you two ways to wear them.
• Best for light, all-day office and commute use → JBL Soundgear Sense: lower weight per bud and a hybrid design tuned for switching between music focus and awareness.
• Best for multipoint across two devices → EarFun OpenJump Open Ear: Bluetooth 5.3 multipoint is explicitly listed.
• Best if you want a charging case in the box → JBL Soundgear Sense: the set ships with a wireless charging case and neckband, while the EarFun bundle lists just a cable and the buds.
I'd buy the EarFun OpenJump Open Ear. In my opinion, the 42-hour total battery, IPX7 waterproofing, LDAC Hi-Res audio, and four-mic call setup cover more real-world situations than a rotating hook does — especially if you run, ride, or work outdoors. The JBL Soundgear Sense is the smarter pick only if a neckband and re-angleable fit matter more to you than endurance and water resistance. Everything else here is a trade-off you can live with either way.
how to open ear headphones work
Open-ear headphones sit outside your ear canal rather than sealing it. Both of these use air conduction: drivers aim sound toward your ear while leaving the canal open, so music and ambient sound reach you at the same time. The JBL uses OpenSound Tech to reduce leakage; the EarFun uses directional acoustics with LDAC and BassSurge tuning.
how to wear open ear headphones
Hook the curved arm over the top of your ear so the driver rests just outside the canal opening. The JBL's earhooks rotate, so you can angle them toward your ear for music or away for more awareness, and you can add the included neckband for a more secure fit. The EarFun's double-curved hook is adjustable but not rotatable, so set it once and leave it.
how to use open ear headphones
Pair over Bluetooth 5.3, then use the touch controls on each bud for playback and calls. The EarFun supports multipoint so it can stay connected to two devices at once and offers Google Fast Pair on Android. The JBL charges via USB-C and includes a wireless charging case; the EarFun charges by cable and gives about 2 hours of playback from a 10-minute top-up.
how to open ear headphones — if you're asking how to keep them clean and lasting, note the ratings: the EarFun's IPX7 means it handles sweat and rain, while the JBL's IP54 is splash-resistant only. Wipe the earhooks after workouts either way, and check the current price on Amazon for both before you commit.
