How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want an in-ear, noise-blocking set with a charging case that keeps you going for days between top-ups, choose SGNICS Earbuds; if you need open-ear headphones that let you hear traffic, your running partner and the world around you while you train, choose Ortizan Open Ear Headphones. Two very different ways to listen to the same playlist, and picking the wrong one is the whole reason this comparison exists.
• SGNICS Earbuds — biggest strength: a true wireless in-ear design with ear hooks, active noise cancellation, four microphones for calls, a 9-hour single-charge runtime and a 500mAh case that carries you toward 48 hours of total playback.
• SGNICS Earbuds — biggest trade-off: they sit inside your ear canal, which is exactly what some people can't tolerate for hours, and the ear-hook shape is a deliberate sport look rather than a discreet everyday one.
• Ortizan Open Ear Headphones — biggest strength: 19 grams of aviation-grade liquid silicone that never enters the ear canal, with air-conduction drivers angled at your ear so music lands where it should while ambient sound still gets through.
• Ortizan Open Ear Headphones — biggest trade-off: open-ear means you can't shut the world out. No noise cancelling here, and the sound is carried by air toward your ear rather than sealed in.
• Pick SGNICS Earbuds if you want bass you can feel, calls that stay clear in a noisy gym, and a case you only charge every few days.
• Pick Ortizan Open Ear Headphones if you run, cycle or ride where you need to stay aware of your surroundings, and you want to forget you're wearing anything at all.
The SGNICS X13 is built around one idea: stay locked in your ears no matter what you're doing. The ear hooks are soft, flexible and shaped to hold on through running, lifting or a sweaty circuit, and you get three sizes of silicone tips (S/M/L) so you can actually seal the canal properly. That seal is the whole point — it's what gives you the deep bass and crisp treble the acoustic setup is tuned for, and it's what lets the active noise cancellation do its job.
Then there's the call side. Four microphones paired with environmental noise cancelling are meant to keep your voice clear when you're talking mid-workout, which is the scenario where cheap earbuds usually fall apart. Bluetooth 5.3 handles the connection, and the IPX6 rating means sweat and rain aren't a problem. Battery is the quiet win: 9 hours on a single charge, roughly 48 hours total with the 500mAh case, and USB-C refills that case in about 1.5 hours. If you hate charging things, that's a genuinely good rhythm — charge the case, not the buds.
Who should buy it: gym-goers, runners, and anyone who wants their music to block out the clanking and chatter around them. It's also the better pick if you take a lot of calls while moving, or if you want one set that works across iPhone, Android, Samsung Galaxy and basically anything with Bluetooth. Who should skip it: if you can't stand the feeling of tips inside your ear canal, or if you need to hear traffic and surroundings while you ride, this is the wrong category of product for you — no amount of good tuning fixes that.
The Ortizan OpenCirclet I10 takes the opposite approach. Nothing goes into your ear. The buds cradle outside the canal, the whole unit weighs just 19 grams, and the frame is made from aviation-grade liquid silicone. That combination is aimed squarely at people who find normal earbuds painful after an hour — the kind of discomfort that makes you fidget and constantly reseat them. With these, the pitch is that you simply forget they're on.
Sound comes from 14.2mm dynamic drivers using air-conduction technology: multi-stage sound cavities angle the audio toward your ear canal at a specific direction, so you get music delivered where you want it while reducing leakage in other directions. You won't get the sealed-in thump of an in-ear bud, but the driver size suggests real presence, and 16-ohm impedance with a 20KHz frequency response is an easy load for a phone to drive. IPX6 waterproofing is here too, so rain and sweat are covered.
Battery runs up to 10 hours of continuous playtime on a roughly 2-hour charge, and magnetic fast charging gives you about an hour of playback from a 10-minute top-up — the gold-plated contacts are there specifically to resist sweat corrosion over time. Bluetooth 5.3 with SBC and AAC decoding keeps the connection stable and latency low, and the built-in mic uses noise reduction for calls. Worth knowing: there's no noise cancelling, and volume is adjusted on your phone rather than on the headset. The package includes the headphones, a magnetic charging cable and a manual, and it's backed by a 1-year manufacturer warranty.
Who should buy it: runners, cyclists, walkers and commuters who want music without cutting themselves off from the environment. Also anyone whose ears just don't get along with in-ear tips. Who should skip it: if you want isolation, deep sealed bass, or a charging case that lives in your pocket, this isn't it.
Side-by-Side: Which Should You Choose?
• Best for noise isolation → SGNICS Earbuds. Active noise cancellation plus a sealed silicone tip is a fundamentally different experience from an open design.
• Best for all-day comfort if in-ears hurt → Ortizan Open Ear Headphones. 19 grams and no ear-canal insertion versus a hooked in-ear fit.
• Best for total battery life → SGNICS Earbuds. 9 hours per charge plus a 500mAh case for roughly 48 hours total, against 10 hours per charge and no case.
• Best for quick top-ups → Ortizan Open Ear Headphones. About an hour of playtime from a 10-minute magnetic charge; SGNICS instead relies on a 1.5-hour USB-C case charge.
• Best for calls in noisy places → SGNICS Earbuds. Four microphones with environmental noise cancelling are aimed at exactly that problem.
• Best for gym and lifting → SGNICS Earbuds. The ear hooks and sealed fit resist movement and let you focus.
• Best for cycling and outdoor running → Ortizan Open Ear Headphones. IPX6 plus open ears is the safer combination on the road.
If I had to pick one, I'd buy the SGNICS Earbuds. In my opinion, the combination of active noise cancellation, four-mic calls, a secure ear-hook fit and a case that stretches playback toward 48 hours makes it the more complete everyday product — it does the gym, the commute and the phone call without compromise. The Ortizan is the better tool for one specific job: outdoor training where hearing the world around you matters more than blocking it out. If that's your job, buy the Ortizan. If you want one pair that handles everything else, the SGNICS X13 is my recommendation. Either way, check the current price on Amazon before you commit.
Both are IPX6 and both are built for sport, so it comes down to awareness. Ortizan's open design lets you hear traffic and surroundings, which many outdoor runners prefer. SGNICS stays sealed in with ear hooks, which suits treadmill and gym work where you want the noise blocked out.
Do Ortizan Open Ear Headphones have noise cancelling?
No. The spec sheet lists noise control as none — the only noise handling is the microphone noise reduction for calls. That's the deliberate trade-off of an open-ear design: you keep ambient awareness instead of isolating yourself.
It depends on your ears. Ortizan is 19 grams of liquid silicone with nothing inserted into the ear canal, which suits people who find in-ears uncomfortable. SGNICS gives you three tip sizes and flexible ear hooks for a secure, sealed fit — comfortable if you tolerate in-ear buds, irritating if you don't.
Yes. Both use Bluetooth 5.3 and neither has a headphone jack, so they connect wirelessly to phones, tablets and computers. Ortizan notes a Bluetooth range of 33 feet. One quirk: Ortizan adjusts volume through your phone rather than on the headset, and iPhone users may need to turn off "Reduce Loud Sounds" in settings if volume seems low.
