If you want an open-ear design that keeps you aware of traffic and conversation while staying put through sweat and rain, choose LCORDN Open Ear Earbuds; if you need maximum battery life with a sealed in-ear fit and a charging case that tops up fast, choose JBMI Earbuds.
• LCORDN Open Ear Earbuds — biggest strength: a 5.1g-per-bud clip-on design that never plugs your ear canal, with Bluetooth 5.4, IPX5 protection and up to 36 hours of claimed playtime.
• LCORDN Open Ear Earbuds — biggest trade-off: open-ear sound means you always hear your surroundings, so it will never isolate you the way a sealed in-ear bud does, and it has no charging case or LED power display in the specs.
• JBMI Earbuds — biggest strength: up to 60 hours total with the charging case, four noise-cancelling microphones for calls, a 60ms low-latency mode and an LED battery display.
• JBMI Earbuds — biggest trade-off: its waterproofing is listed as IP5, which is a splash-and-sweat rating, not a rating built for heavy rain or full submersion, despite what the marketing description hints at.
• Who each pick is for: LCORDN for runners, cyclists and glasses wearers who want awareness and all-day comfort; JBMI for commuters, call-heavy users and anyone who wants the longest possible time between charges.
The LCORDN pair is built around one idea: keep your ears open. Each bud weighs just 5.1g and clips on rather than sealing into your canal, so there is nothing pressing inside your ear for hours at a time. If you have ever given up on earbuds because they ached after an hour, or because they fought with the arms of your glasses, that clip-on shape is the whole point. It is also why they stay put during a run or a long ride — the fit does not depend on a silicone tip wedging itself into your ear.
Sound-wise, LCORDN uses 13mm dynamic drivers with dual-composite diaphragms and a directional audio design that aims the sound at you while cutting leakage. The frequency range is the standard 20Hz–20kHz, so expect a full-range presentation rather than something exotic. The honest trade-off is that open-ear audio is not private in the same way sealed buds are — you hear the world, and the world hears a little of you. The upside is exactly what outdoor athletes want: you can hear a car, a cyclist's bell or a training partner without pulling a bud out.
Battery is where LCORDN leans on its claim: up to 36 hours of playtime, with a single charge taking about an hour and a rated average life of 8 hours per charge cycle. Touch controls handle volume, playback, calls and voice assistants, and Bluetooth 5.4 gives you a 10-meter wireless range. In my opinion, this is the pair to buy if your priority is comfort and situational awareness — running, cycling, gym sessions, walking the dog, wearing glasses. Skip it if you want total noise isolation on a plane or in a loud open office, because that is the one thing an open-ear design cannot give you.
The JBMI Earbuds take the traditional route: in-ear tips that seal your canal, a charging case, and a spec sheet obsessed with runtime. The headline number is up to 60 hours when you count the case, with 6–7 hours on a single full charge at 60% volume. Type-C charging is quick too — 10 minutes gets you roughly an hour of use. There is also an LED digital display on the case that shows remaining power, which is a genuinely useful detail if you have ever been caught out by a dead pair of buds with no warning.
Audio is handled by 13mm dynamic drivers with high-amplitude composite biofiber diaphragms, tuned for deep bass and a wide stereo stage, with a frequency range of 20Hz–20kHz. Bluetooth 5.4 keeps power draw down and transmission fast, and a 60ms low-latency mode plus SBC and AAC support makes them a reasonable pick for video and casual gaming. For calls, four noise-cancelling microphones work together to push down background noise — that is a much more serious call setup than a single mic, and it is the feature I would weigh most heavily if you take meetings on the move.
Here is where I would slow you down: the waterproofing. JBMI lists IP5, which covers splashes, sweat and light rain. The product description mentions IP7 and IPX5 in different places, but the item details say IP5, so I would plan around the lower, more conservative figure and not treat these as swim-or-soak buds. They are also in-ear only, so no awareness mode and no sharing your surroundings. Buy them if you want long battery life, a sealed fit for commuting or the gym, and strong call clarity. Skip them if you specifically need to hear traffic while you run, or if you wear glasses and want nothing touching your ear canal.
• Best for battery life → JBMI Earbuds. Up to 60 hours with the case beats LCORDN's 36-hour claim, and the LED display removes the guesswork.
• Best for awareness and safety outdoors → LCORDN Open Ear Earbuds. The open-ear clip design lets ambient sound in, which matters on roads and trails.
• Best for glasses wearers → LCORDN Open Ear Earbuds. Nothing sits inside the canal or presses against the arms of your frames.
• Best for call quality in noisy places → JBMI Earbuds. Four noise-cancelling microphones versus a single-mic setup.
• Best for all-day comfort → LCORDN Open Ear Earbuds. At 5.1g per bud with no ear-tip pressure, they are the easier wear over a long day.
• Best for low-latency video and gaming → JBMI Earbuds. The 60ms latency mode is the more explicit gaming-oriented spec.
• Best for fast top-ups → JBMI Earbuds. Ten minutes of Type-C charging for about an hour of listening is the more practical emergency option.
• Best for heavy rain and hard sweaty sessions → LCORDN Open Ear Earbuds. It carries a clear IPX5 rating, while JBMI's listed IP5 is the more conservative splash-level claim.
If I had to pick one, I would take the LCORDN Open Ear Earbuds. The reasons are practical rather than dramatic: an IPX5 rating I can trust for sweat and rain, a 5.1g clip-on fit that works with glasses, Bluetooth 5.4, and enough playtime that charging becomes a weekly chore instead of a daily one. The open-ear design is a genuine limitation if you want silence, but for running, cycling and everyday wear it is the feature that makes them worth owning. Choose the JBMI Earbuds instead if battery life and call clarity in noisy rooms matter more to you than hearing the world around you. Either way, check the current price on Amazon before you commit — that is the one number this comparison deliberately leaves to you.
are headphones waterproof
Not usually — and neither of these two is fully waterproof. LCORDN lists IPX5, which handles sweat and rain spray, and JBMI lists IP5, a splash-and-sweat level of protection. Neither rating means you should submerge them or swim with them.
are headphones water resistant
Yes, both of these qualify as water resistant. LCORDN's IPX5 rating is the stronger of the two on paper, while JBMI's listed IP5 covers splashes, sweat and light rain. If you want the safer bet for hard workouts and wet weather, I would lean toward the LCORDN pair.
LCORDN uses directional sound technology specifically to reduce leakage, but open-ear designs are still less private than sealed in-ear buds. At high volume, someone sitting close to you may pick up some of what you are playing.
Yes — that is one of their stated strengths. The clip-on shape avoids your ear canal entirely, so it does not compete with the arms of your glasses or cause the pressure that in-ear tips create over long sessions.
