If you want an open-ear headphone that keeps you aware of traffic and conversation while you run, ride or walk, choose CXK Bone Conduction Headphones; if you need over-ear cans that block out the world with active noise cancelling and run for days between charges, choose MMWOWARTS Headphones.
These two share almost nothing except the word "Bluetooth." One sits on your cheekbones and leaves your ears open. The other seals over your ears and cancels noise. That single design difference decides almost everything else, so let's break it down properly.
• CXK's biggest strength: an open-ear bone conduction design with a 28g flexible titanium frame — you hear your music and your surroundings, which is exactly what outdoor athletes want.
• CXK's biggest trade-off: bone conduction can't physically seal out noise, and the claimed waterproofing is inconsistent between the title (IPX6) and the spec list (IPX7). Neither version is for swimming.
• MMWOWARTS's biggest strength: hybrid active noise cancelling with 35 hours of playtime and a 3.5mm jack for wired listening when you want zero latency.
• MMWOWARTS's biggest trade-off: it's a traditional over-ear design, so you lose all ambient awareness — a real problem on a bike or a busy road.
• Buy CXK if you're a runner, cyclist or walker who wants situational awareness and a barely-there fit.
• Buy MMWOWARTS if you want to shut out an open-plan office, a plane cabin or a noisy commute.
The CXK X13 is built around one idea: your ears stay open. Sound travels through a bone conduction driver — a 15mm unit with 10 ohm impedance — pressed against the area in front of your ear rather than fired into a sealed ear canal. In practice that means you can hear a car approaching, a cycling bell, or a colleague saying your name without pulling anything out of your ear. For anyone who exercises near traffic, that's not a gimmick, it's the whole point.
The comfort story backs it up. The frame is flexible titanium wrapped in soft silicone, and the whole thing weighs 28g. That's light enough that the wraparound design mostly disappears, and because nothing plugs your ear canal, you don't get the pressure build-up or the fatigue that comes with long sessions in sealed earbuds. Bluetooth 6.0 handles pairing and the wireless link, and there's a built-in mic for calls. Battery life is rated at 10 hours with a 2-hour recharge over magnetic contacts — enough for a week of commutes or a couple of long rides.
The Boean companion app is the sleeper feature. It includes customizable EQ profiles so you can push bass, lift vocals, or pick a genre preset, plus an AI song-generation mode that turns a mood or an idea into an original track. It's a novelty, but it's a genuinely different one.
Who should skip it: anyone who wants to escape noise. Bone conduction has no passive isolation to speak of, and the noise control here is listed as sound isolation, not cancellation. On a plane or a loud train you'll be turning the volume up to compete with the environment. And despite the waterproof rating, the sheet explicitly says it's not suitable for swimming — sweat and rain yes, laps no.
The MMWOWARTS set is the opposite philosophy. These are over-ear headphones with foam ear cups and hybrid active noise cancelling — the kind of design that physically covers your ears and then adds electronics to cancel what's left. Hybrid ANC uses microphones inside and outside the cup, which generally handles a wider band of noise than a single-mic setup. If your problem is a droning engine, an air conditioner, or the general hum of a shared office, this is the tool built for it.
Battery is the headline number: 35 hours of average life. That's more than three times the CXK's rated playtime, and it changes how you live with the product. You charge it on the weekend, not every other day. Bluetooth 5.4 handles the wireless connection with a 10-meter range, and there's a 3.5mm jack — which matters more than it sounds. A wired option means you can plug into a laptop, a seat-back entertainment system, or a gaming controller without worrying about pairing or latency.
The design is a classic foldable over-ear in solid black, with button controls rather than touch. Buttons are less fashionable, but they're reliable in cold weather or with gloves, and you always know you've pressed one. The package includes an owner's manual, and the manufacturer warranty is listed at 90 days — worth knowing up front, because that's shorter than what many buyers assume by default.
Who should skip it: anyone who needs to hear what's happening around them. Sealed cups plus ANC is the worst possible combination for running on a road or riding in traffic. And if you hate the feeling of pressure around your ears during long sessions, the over-ear format will bother you where the CXK wouldn't.
• Best for situational awareness → CXK Bone Conduction Headphones. Open-ear by design, so traffic, voices and alarms come through.
• Best for blocking noise → MMWOWARTS Headphones. Hybrid active noise cancelling with sealed foam ear cups.
• Best for battery life → MMWOWARTS Headphones. 35 hours versus 10 hours is not a close comparison.
• Best for all-day comfort in a minimal package → CXK Bone Conduction Headphones. 28g, flexible titanium, no ear-canal pressure.
• Best for wired fallback and low latency → MMWOWARTS Headphones. It has a 3.5mm jack; the CXK is wireless-only with no jack at all.
• Best for sweaty workouts and rain → CXK Bone Conduction Headphones. Waterproof-rated against sweat and rain (but not swimming).
• Best for long-haul travel and office focus → MMWOWARTS Headphones. Cancellation plus a 90-day warranty and foldable storage.
• Best for tinkering with sound → CXK Bone Conduction Headphones. The Boean app's custom EQ and AI song tools are unique to it.
If I had to pick one, I'd buy the CXK Bone Conduction Headphones — but only because my priority is training outdoors while staying aware of my surroundings, and that's the one job the MMWOWARTS set simply cannot do. The 28g titanium frame, the open-ear design and the app-based EQ make it a focused, honest tool for runners, cyclists and walkers. In my opinion, though, if your life is mostly planes, offices and noisy commutes, the MMWOWARTS Headphones are the smarter buy: 35 hours of battery and real active noise cancelling beat open-ear awareness in that environment every time. Pick the one that matches where you'll actually wear it, and check the current price on Amazon before you commit.
how to headphones work
Traditional headphones like the MMWOWARTS set push sound through drivers into sealed ear cups, and hybrid ANC adds microphones that sample ambient noise and cancel it electronically. Bone conduction models like the CXK skip the ear canal entirely — a driver vibrates against your cheekbone and your inner ear picks up the vibration directly, which is why your ears stay open.
how to headphones on iphone
Both are standard Bluetooth headphones, so the process is the same on an iPhone: open Settings, go to Bluetooth, and select the device from the list. Put the headphones in pairing mode first — the CXK uses Bluetooth 6.0 and the MMWOWARTS uses Bluetooth 5.4, and both pair as normal wireless audio devices. The MMWOWARTS also has a 3.5mm jack, so you can go wired if you have the right adapter.
how to headphones noise cancelling
Only the MMWOWARTS set has active noise cancelling, and it works by generating sound that cancels incoming noise — best on steady low-frequency sounds like engines and fans. The CXK uses sound isolation instead, which is a passive effect, and its open-ear design means very little noise is blocked at all. If cancellation is your priority, that alone settles the choice.
how to headphones
At the simplest level: charge them, pair them over Bluetooth, and press play. The CXK charges magnetically in about 2 hours for up to 10 hours of playback, while the MMWOWARTS takes a standard charge and runs up to 35 hours. Both use physical button controls rather than touch, so there's no learning curve on either.
