How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a rugged, phone-free training partner built for swimming, running and brutal weather, choose DEMICEA Open Ear Sport; if you need a light, clip-on headset that keeps your voice clear on calls — including long shifts at a call center — choose DUOSSEAR F11. Both are non in ear headphones, so neither one plugs your ear canal, but they solve two very different problems. One is an athlete's music player. The other is a talker's headset.
• DEMICEA Open Ear Sport — biggest strength: a 32GB built-in MP3 player plus an IP68 waterproof rating, so you can swim and train with no phone anywhere near you.
• DEMICEA Open Ear Sport — biggest trade-off: it's a sport tool first. There's no noise cancellation, and the bone conduction design is aimed at movement, not at office chatter.
• DUOSSEAR F11 — biggest strength: a dual-microphone ENC setup built around noise-reduced voice pickup, in an ear-clip shape that stays put without sealing your ears.
• DUOSSEAR F11 — biggest trade-off: the spec sheet is thin. It's a calling-first device, and there's no waterproof rating, storage or battery figure published to lean on.
• Choose DEMICEA if your day involves water, sweat, weather and your own music library.
• Choose DUOSSEAR F11 if your day involves a headset, a microphone and other people's voices.
This one is a wearable music locker. The headline spec is the 32GB of built-in storage — enough for over 4,000 songs, loaded through the magnetic data-and-charging cable. That single feature changes how you train: you can leave the phone in a locker, on a pool deck or at home and still have your full playlist. If you've ever cut a run short because your phone was bouncing in a pocket, that's the problem this design is built to delete.
The hardware backs it up. The frame is a 0.7mm flexible memory titanium alloy with a skin-friendly silicone rear bridge, and the whole thing weighs 26 grams (0.99 oz). The weight is balanced so it doesn't fight your sunglasses, and the front-of-ear silicone cushions are there to sit gently rather than press. The driver is a 16mm bone conduction unit with SoundBeam directional field technology, which the manufacturer says keeps audio from leaking sideways — useful when you're on a quiet trail and don't want to broadcast your podcast.
Buy it if you swim, run or lift and want your music stored on the headphones themselves, or you want one pair that survives weather you'd never trust normal earbuds in. Skip it if you mainly need a microphone for meetings and calls — noise control is listed as none, and the bone conduction mic position isn't built around conference audio.
DUOSSEAR F11: Who It's For
The F11 is a different animal, and it's honest about it. The entire pitch is the ear-clip, non in ear format plus dual microphones with ENC noise reduction for calls. ENC means environmental noise cancellation — it's about cleaning up what the other person hears on the call, not about blocking sound from reaching your ears. For anyone who lives on voice calls, that's the spec that matters, and it's the reason this pair belongs in a conversation about call-center and remote-work headsets.
The ear-clip shape is worth thinking about too. Nothing enters the canal, so there's no pressure, no wax pushing, no "plugged" feeling after an hour of talking. You keep ambient awareness, which is genuinely useful if you're taking calls while moving around a house, an office or a warehouse floor. Sound travels by bone conduction, and the frequency range matches the DEMICEA at 20Hz–20,000Hz. It's Bluetooth wireless with no jack, and it's a single-item package in green.
Buy it if your priority is being understood on calls, you want an open, hygienic fit you can wear for long stretches, or you want a clip-on that doesn't disappear into your ear. Skip it if you need waterproofing for swimming, on-board music storage, or published battery figures — none of those are in the specifications for this model. The publicly listed spec sheet here is short, so treat it as a calling-focused device rather than an all-rounder.
Side-by-Side: Which Should You Choose?
• Best for swimming and heavy sweat → DEMICEA Open Ear Sport. IP68 with a sealed body and hydrophobic coating is the whole argument.
• Best for phone-free workouts → DEMICEA Open Ear Sport. 32GB of internal storage for over 4,000 songs means no paired device required.
• Best for all-day wear comfort → DUOSSEAR F11. The ear-clip, non in ear format avoids canal pressure entirely.
• Best for battery planning → DEMICEA Open Ear Sport. It's the only one of the two with published figures: up to 8 hours, 2-hour charge, 5-minute quick top-up.
• Best for long-range and low-latency claims → DEMICEA Open Ear Sport. Bluetooth 5.3 with a stated 16ms latency and AAC/SBC support.
• Best for durability backup → DEMICEA Open Ear Sport. An 18-month warranty is documented for this model.
• Best for the lightest possible footprint → DUOSSEAR F11. Ear-clip designs typically sit lighter than a rear-bridge headband, and there's no headband to snag on a collar.
For a call center or any job where your voice is the product, I'd buy the DUOSSEAR F11. Dual-mic ENC plus an ear-clip fit that never blocks your ear is exactly the right combination for hours of talking, and it keeps you aware of what's happening around your desk. If your priority is training — especially swimming — I'd take the DEMICEA Open Ear Sport instead, because 32GB of on-board music and IP68 waterproofing are things the F11 simply doesn't offer. Two different jobs, two different picks. In my opinion, match the tool to the task and you'll be happy either way.
how do non ear headphones work
Non in ear headphones sit outside the ear canal instead of inside it. Bone conduction models like these two send vibration through the bone in front of your ear, which your inner ear reads as sound. That's why you still hear traffic, coworkers and announcements while wearing them.
what are non in ear headphones called
They're usually called open-ear headphones. Depending on the design, you'll also see them described as bone conduction headphones, air conduction headphones or ear-clip headphones. Both products here are bone conduction open-ear models.
how to wear in ear headphones
In-ear headphones push a tip into your ear canal to seal it. You insert the tip, then rotate it gently until it sits snug and the seal holds. If it feels painful or keeps falling out, the tip size is wrong — try a different one rather than forcing it.
what are the best open ear headphones
There's no single answer, because "best" depends on the job. For swimming, sweat and phone-free music, I'd point to the DEMICEA Open Ear Sport. For calls, meetings and all-day talking comfort, I'd point to the DUOSSEAR F11. Check the current price on Amazon for each and decide based on which use case matches your week.
