• LCORDN's biggest strength: an open-ear hook design with 360° ambient awareness plus IPX7 waterproofing — you hear traffic and your music at the same time, and sweat or rain doesn't end the session.
• LCORDN's biggest trade-off: open-ear means sound leaks in both directions. It is not a sealed, isolating listen, and the hook fit is a very different feel from a cushion resting on your head.
• Yechiry's biggest strength: a foldable over-ear build with active noise cancelling, soft sponge cushions, a rotating headband and a 40mm driver — a classic sit-down listening shape made for travel and study.
• Yechiry's biggest trade-off: 6 hours per charge and no water-resistance rating in the spec sheet. It is a desk-and-cabin product, not a gym product.
• Buy LCORDN if you run, ride, commute, or want your ears open to the world.
• Buy Yechiry if you want an enclosed, foldable headset for a younger listener on trips and homework sessions.
The LCORDN set is built around one idea: keep the ear canal open. The earpieces hook over the ear rather than plug into it, so sound reaches you while ambient noise still gets through. In practice that means you can hear a car behind you on a ride, a colleague calling your name at the gym, or an announcement at a gate without pulling anything out of your ears. If you have ever found in-ear buds uncomfortable after an hour, the pressure-free approach here is the main selling point.
Battery is the other headline. LCORDN states 10 hours of playback on a single charge, extended to 60 hours with the 500mAh charging case, and a 10-minute top-up yields 2 hours of listening. The case recharges over Type-C in about an hour and shows battery percentage on an LED display. That combination — long single-charge runtime, a quick-charge escape hatch, and a visible battery readout — is what makes these genuinely usable for a full training week or a long trip without babysitting a cable.
Who should skip it? Anyone who wants to be sealed off from the world. If your priority is blocking out engine drone or a noisy office, an open-ear design is working against you by definition. And if you want the physical feel of cushions around your ears, this is the wrong shape entirely.
Yechiry Over Ear Headphones: Who It's For
Yechiry takes the opposite approach: enclose the ear and fold the whole thing up when you're done. The cushions are soft elastic sponge, the headband rotates and adjusts, and the headset folds for packing. That is a travel-first design, and it is aimed squarely at kids — the product is positioned for children's learning and entertainment, which shapes both the fit and the feature list.
The listening experience is built on a 40mm dynamic driver with a 20Hz–20kHz frequency response, 32 ohm impedance and stereo output, paired with Bluetooth 5.3. Active noise cancelling is on board, which is unusual at this end of the kid-headphone world and is the feature that makes it useful on a plane, in a car, or in a house where someone else is watching TV. Supported protocols are A2DP, AVRCP and HSP, so it pairs with phones, computers, TVs and anything else Bluetooth. The spec sheet also lists a separate microphone in the box alongside a charging cable and an audio cable, and the headset provides low-latency vocal pickup for calls or practice sessions.
Battery is where Yechiry is honest and modest: up to 6 hours of continuous use from a 500mAh lithium battery. For a school day, a homework block or a medium-haul flight leg, that is workable. For a full long-haul itinerary or a week of camp, you will be recharging nightly. There is also no water-resistance rating in the data — treat it as an indoor and dry-weather product. The warranty is 90 days, notably shorter than LCORDN's two years.
Side-by-Side: Which Should You Choose?
• Best for battery life → LCORDN Open Ear Headphones. 10 hours per charge and up to 60 hours with the case, versus 6 hours total for Yechiry.
• Best for workouts and weather → LCORDN Open Ear Headphones. IPX7 waterproofing and a stable ear hook; Yechiry lists no water-resistance rating.
• Best for situational awareness → LCORDN Open Ear Headphones. Open-ear design with 360° ambient awareness is the entire premise.
• Best for blocking out noise → Yechiry Over Ear Headphones. Active noise cancelling plus enclosed sponge cushions.
• Best for kids → Yechiry Over Ear Headphones. It is explicitly designed and sized for children, with an adjustable rotating headband.
• Best for travel and packing → Yechiry Over Ear Headphones. The foldable over-ear format stows far more easily than a charging case full of buds — though LCORDN's case is compact in its own right.
• Best for calls and voice pickup → a close call. LCORDN has a mic in each earbud; Yechiry ships a dedicated microphone and emphasizes low-latency vocal feedback.
• Best for long-term peace of mind → LCORDN Open Ear Headphones. Two-year manufacturer warranty against Yechiry's 90 days.
If I had to pick one for myself, I'd take the LCORDN Open Ear Headphones. The combination of 60-hour total runtime, IPX7 protection, Bluetooth 5.4 and the two-year warranty covers far more of my actual week — runs, commutes, calls, travel — than a 6-hour enclosed headset would. That said, if the person you're buying for is a child who needs to focus on a plane or at a desk, the Yechiry's noise cancelling, sponge cushions, foldable frame and rotating headband are the better-matched design. Buy for the use case, not the category. Do check the current price on Amazon for whichever one you land on, since that is the variable most likely to tip a close call.
LCORDN, by a wide margin. It lists 10 hours per charge and up to 60 hours with the charging case, plus a 10-minute quick charge for 2 hours of playback. Yechiry lists up to 6 hours of continuous use on a single charge.
The spec sheet says IPX7 waterproofing, which covers sweat, rain and splashes, and the ear hook is described as staying secure during vigorous exercise. That makes them the more sensible choice of the two for wet-weather training. Yechiry lists no water-resistance rating.
That is exactly what they are built for. They are positioned for children's travel and learning, with soft elastic sponge cushions, an adjustable rotating headband, a foldable frame and active noise cancelling for noisy environments. Just plan on charging them every day or two given the 6-hour runtime.
Both cover the basics. LCORDN has a built-in HD microphone in each earbud with hybrid noise cancellation. Yechiry includes a dedicated microphone in the box and highlights low-latency directional pickup for clear vocals. For calls taken on the move, I'd lean LCORDN; for calls taken sitting down, Yechiry is perfectly capable.
