How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want week-long battery life and a clip-on fit that plays nice with glasses, choose LCORDN Open Ear Earbuds; if you need a bend-proof titanium frame built for hard training sessions, choose Gelecek Bone Conduction Headphones. Both carry an IPX5-level water resistance claim aimed at sweat and rain, so the real split isn't waterproofing — it's how each one sits on your head and how long it runs between charges.
• LCORDN's biggest strength: a claimed 36 hours of total playtime from a 5.1g-per-bud clip-on design, plus Bluetooth 5.4 and touch controls.
• LCORDN's biggest trade-off: each bud's average life is only 8 hours and a full charge takes about an hour, so long single sessions need a case top-up.
• Gelecek's biggest strength: a 29g titanium frame that flexes and springs back, with a claimed 10 hours per charge and up to 50% less sound leakage.
• Gelecek's biggest trade-off: 10 hours total is a fraction of LCORDN's claim, and the specs list IP55 alongside IPX5, so the water rating isn't stated consistently.
• Pick LCORDN if you wear glasses, want all-day comfort, and hate charging.
• Pick Gelecek if you run, hike or lift hard and want a headband that survives being bent and tossed in a bag.
The LCORDN pair is built around weight and endurance. Each earbud comes in at 5.1g and clips over the ear rather than plugging into it, which is the detail that matters most if you wear glasses — there's no stem fighting your temples and no tip pressing into your ear canal. The spec sheet lists a plastic enclosure, a black finish, 13mm dynamic drivers, a 16-ohm impedance and a 20Hz–20,000Hz frequency range, so the tuning is conventional full-range rather than anything exotic. Directional sound is claimed to keep leakage down, which is the usual weak point of open designs.
The headline number is battery. LCORDN claims 36 hours of playtime, with an average bud life of 8 hours and roughly a one-hour charge time. Read that the way it's meant: 8 hours in the buds, the rest banked in the case. For a commuter or a desk worker who drops them in and out all day, that adds up to something you charge about once a week instead of every night. Bluetooth 5.4 and a 10-metre range cover the normal phone-in-pocket, phone-on-the-desk cases, and touch control handles volume, playback, calls and voice assistants without pulling your phone out.
Buy these if you want one pair for the whole day — calls, podcasts, cycling, gym — and you're tired of buds that go dead by mid-afternoon. Skip them if you do multi-hour continuous sessions, because the 8-hour per-charge figure will bite you, and skip them if you specifically want bone conduction rather than a speaker aimed at your ear. One more thing worth knowing: the box includes the clip-on headphones, one pair of buds, a USB-C cable and a manual, with a one-year manufacturer warranty.
Gelecek takes the opposite approach: one piece, worn as a band, sending sound through your cheekbones instead of into your ear canal. The frame is titanium at 29 grams, and the point of that material is durability — it's described as flexing and bending without deforming, which is exactly what you want from something that lives in a gym bag. The colour is listed as Audi Cloudy Gray, the driver type is a bone conduction driver, and the connection is Bluetooth 5.4 with a mic and noise cancellation for calls.
The safety argument is the real selling point here, and it's a legitimate one. Because nothing blocks your ears, you hear traffic, other runners and gym announcements while your audio plays. Gelecek also claims a fully enclosed cavity that cuts sound leakage by up to 50%, which addresses the classic bone-conduction complaint that everyone around you hears your podcast.
Battery is where this one gives ground: a claimed 10 hours per charge, with Type-C charging, versus LCORDN's 36-hour claim. That's a full day of training and commuting, but it means charging most days rather than weekly. There's also a spec inconsistency to flag — the bullet points say IPX5 waterproof and sweatproof, while the product details list the water resistance level as "Water Resistant" and mention IP55. Both point to sweat-and-splash protection, not swimming, but the two ratings don't line up, so treat it as rain-and-sweat safe and nothing more.
Buy these if you run outdoors, cycle in traffic, or want a band that won't shift during burpees. Skip them if you wear glasses and find headbands annoying, or if you want maximum hours between charges.
Side-by-Side: Which Should You Choose?
• Best for maximum single-session runtime → Gelecek Bone Conduction Headphones. 10 hours in one go beats LCORDN's 8-hour per-bud average before any case top-up.
• Best for glasses wearers → LCORDN Open Ear Earbuds. The clip-on open-ear shape is explicitly aimed at people who wear glasses.
• Best for durability and rough handling → Gelecek Bone Conduction Headphones. The titanium frame is designed to be bent and stretched without deforming.
• Best for outdoor safety and awareness → tie, narrowly Gelecek. Both leave your ears open, but bone conduction is the design built around that idea first.
• Best for private listening in shared spaces → Gelecek Bone Conduction Headphones. It claims up to 50% less leakage; LCORDN's directional audio aims at the same problem without a figure.
• Best for all-day comfort you forget about → LCORDN Open Ear Earbuds. 5.1g per bud is far lighter than a 29g band on your head.
• Best for call clarity and touch convenience → LCORDN Open Ear Earbuds. Touch controls and a mic are listed directly, plus Bluetooth 5.4.
• Best for water resistance clarity → LCORDN Open Ear Earbuds. A clean IPX5 claim beats a sheet that says IPX5 in one place and IP55 in another.
I'd buy the LCORDN Open Ear Earbuds. The combination of 5.1g per bud, a clip-on shape that doesn't fight glasses, Bluetooth 5.4, touch controls and a claimed 36 hours of total playtime covers more of my day than a 10-hour band does. The IPX5 rating is also stated consistently, which I like. Gelecek is the better pick if you train hard and want a titanium frame that shrugs off abuse — but if you want one pair for work, commuting and workouts without thinking about charging, I'd go with LCORDN. Check the current price on Amazon before you commit, since both sit in the budget-to-mid range.
FAQ
are headphones waterproof
are headphones water resistant
Yes, both of these are. IPX5 on the LCORDN means it's designed to handle sweat and light rain during runs and rides. Gelecek's water resistance level is listed as "Water Resistant," with IP55 and IPX5 both appearing in its specs, so it should cope with sweat and rain but not full immersion.
Gelecek. Its battery life is listed at 10 hours per charge, while LCORDN's buds average 8 hours each with about an hour to recharge. LCORDN wins the total figure — a claimed 36 hours — but only because the case tops the buds up between sessions.
No, and that's the main reason to pick it. With a claimed 36 hours of total playtime and roughly an hour to charge, a normal day of commuting and workouts leaves plenty in reserve. Gelecek's 10 hours means charging most nights if you use it daily.
