• NANAMI Open Ear Headphones biggest strength: a no-pressure open-ear fit explicitly designed for side sleepers, plus 15 hours of playtime and IPX5 water resistance.
• NANAMI Open Ear Headphones biggest trade-off: no noise control at all — it's built for awareness, not isolation, and there's no charging case, just a cable.
• MAMALADY Open Ear biggest strength: TWS true-wireless stereo with a dedicated charging base, five color options, and a hook shape that stays put through activity.
• MAMALADY Open Ear biggest trade-off: the battery life isn't stated as a playtime figure, and the spec sheet lists an in-ear placement that sits awkwardly against the open-ear marketing.
• Pick NANAMI Open Ear Headphones if you fall asleep on your side, wear buds all day, or need sweat resistance.
• Pick MAMALADY Open Ear if you want color choice, a base station for storage and charging, and a more traditional TWS earbud experience.
The NANAMI Open Ear Headphones are a single-piece, ear-hook design with a 14.2 mm dynamic driver and a 20 Hz – 20,000 Hz frequency range. Bluetooth 5.3 handles the connection with a 10-meter range, and the whole thing charges over Type-C in about two hours. The headline number is 15 hours of average battery life — that's a full night plus a workday, which is unusual in this category.
What makes it different is the specific problem it solves. The ear hooks wrap around the outside of your ear rather than pushing anything into the canal, so there's no pressure point when your head is on a pillow. If you listen to podcasts, white noise, or music while falling asleep on your side, that's the whole point of this design. It also carries IPX5 water resistance, so sweat, light rain, and gym sessions aren't a problem. Controls are physical buttons rather than touch, which means no accidental taps when you adjust the hook.
Who should skip it? Anyone who wants to block out the world. There is no noise control here, and the open-ear format leaks in everything — traffic, office chatter, your partner's TV. That's intentional for safety and awareness, but it's the wrong tool for a noisy flight or a loud commute. I'd also steer away anyone who wants a compact charging case; NANAMI ships with a cable, and the buds themselves are the whole package.
The MAMALADY Open Ear takes a different route. It's a TWS setup — true wireless stereo — meaning the two earpieces operate independently, and it ships with a dedicated charging base that doubles as storage. The base measures roughly 3.2 inches wide and 2 inches tall, so it's a small desktop or nightstand object rather than something you'd slip into a pocket. The earbuds themselves weigh about 2.8 ounces total.
The spec sheet here is a mixed bag, and I'd rather be honest about that. The driver is 13.5 mm with 32-ohm impedance, 98 dB sensitivity, and a stated 20 Hz low end. Bluetooth is version 5 with a 33-foot range, and latency is listed at 50 milliseconds — a figure that matters if you're watching video or gaming and don't want lip-sync drift. Controls are push-button and touch combined.
Here's my honest read: the listing describes an outside-ear hanging design and air conduction, but the product information fields list the ear placement as "in ear" and the shape as "hook." Those two things don't fully agree, and a buyer should go in knowing the marketing language and the structured specs pull in slightly different directions. There's also no stated playtime figure, which is the single biggest gap compared to NANAMI. What MAMALADY does clearly offer is choice: black, blue, white/silver, pink, and purple. If matching your gear matters to you, that's real.
• Best for side sleepers → NANAMI Open Ear Headphones. It's the only one of the two explicitly designed around lying on your ear without pressure.
• Best for battery confidence → NANAMI Open Ear Headphones. A stated 15-hour average life is concrete; MAMALADY doesn't publish a playtime figure.
• Best for sweat and weather → NANAMI Open Ear Headphones. IPX5 is spelled out on the spec sheet.
• Best for workouts and running → both, but differently. NANAMI's IPX5 plus secure hooks suit heavy sweat; MAMALADY's over-ear hook is built for stability during movement.
• Best for color choice → MAMALADY Open Ear. Five finishes versus NANAMI's single black option.
• Best for storage and charging setup → MAMALADY Open Ear. The included charging base is a genuine convenience NANAMI doesn't have.
• Best for low-latency video → MAMALADY Open Ear. A 50 ms latency figure is listed; NANAMI publishes none.
• Best for range → MAMALADY Open Ear. 33 feet against NANAMI's 10 meters (about 33 feet) — effectively a tie on paper, though Bluetooth 5.3 on the NANAMI is the newer standard.
I'd buy the NANAMI Open Ear Headphones. In my opinion, the 15-hour playtime, IPX5 rating, and the genuinely specific side-sleeper design make it the more useful product for the way most people actually wear open-ear buds — long sessions, workouts, and bedtime. MAMALADY's charging base and color range are nice touches, and its latency spec is a plus for video, but the missing playtime figure and the in-ear/open-ear spec contradiction give me pause. If color matching or a base station is a dealbreaker for you, MAMALADY is the pick. Otherwise, NANAMI.
how to wear ows earbuds
Open-ear buds like these hang outside the ear canal instead of sealing it. On the NANAMI, the ear hook wraps gently over the top and behind your ear, with the driver resting against the outside of the ear. On the MAMALADY, the hook shape does the same job. Adjust until the driver sits forward of the canal, not inside it.
how to use ows earbuds
Power them on, pair once, and they reconnect automatically afterward. NANAMI uses physical buttons for playback and calls; MAMALADY uses a mix of push-button and touch. Because both are open-ear with no noise control, keep volume moderate in noisy places — you're meant to hear your surroundings.
how to connect tws earbuds
TWS means the two earpieces link to each other and to your phone as one device. Take both MAMALADY buds out of the charging base, put them in pairing mode, then select the entry in your phone's Bluetooth list. Once paired, the base handles recharging and the buds reconnect on their own next time.
how to pair ows earbuds
Turn the headphones on and hold the pairing control until the indicator flashes, then open Bluetooth settings on your phone and select the device. NANAMI runs Bluetooth 5.3 and MAMALADY runs Bluetooth 5 — both pair the same way, and both reconnect automatically after the first setup. Check the current price on Amazon before deciding.
