• MZYDM's biggest strength: Bluetooth 5.4 with up to 15 meters of range, a 15 mm bone conduction driver, and just 29 g on your head — plus multipoint connection so you can take a phone call while music on your laptop pauses.
• MZYDM's biggest trade-off: Charging details are not spelled out, and there is no stated fast-charge window, so you plan around its 15 hours rather than topping up in ten minutes.
• Jutaruoo X13's biggest strength: USB-C fast charge — a 10-minute top-up is rated for 2 hours of playback and a full charge in about 1 hour from a 250 mAh battery — with an ENC mic setup and a clear, written multipoint pairing procedure.
• Jutaruoo X13's biggest trade-off: Bluetooth range is stated at 10 meters, and the 140 ohm impedance plus 60 ms latency figure tells you it is tuned for stable everyday listening rather than the punchiest possible driver output.
• Pick MZYDM if you want the lightest-feeling, longest-range pair for workouts, running, and switching between a laptop and a phone.
• Pick Jutaruoo X13 if charging speed, helmet/glasses compatibility, and call clarity in wind and traffic matter more to you.
The MZYDM pair is built around a simple idea: stay aware, stay connected, don't fuss. It uses Bluetooth 5.4, which in practice means quicker pairing, lower latency, and a more stable link than older chipsets. The stated wireless range is 15 meters, so you can leave your phone on a bench or desk and keep moving without the audio stuttering. For anyone who has fought with a headset that drops the moment you walk into the next room, that headroom is the quiet selling point here.
The audio side is where it gets interesting. MZYDM uses a 15 mm bone conduction driver with a 20 Hz–20,000 Hz frequency range, 50 ohm impedance, and 92 dB sensitivity — and a built-in mic for calls. In my opinion, that 15 mm driver is the headline spec: a larger transducer generally moves more air and can deliver fuller sound than the smaller units common in this category. The environmental noise cancellation and push-button controls keep things straightforward — volume, tracks, and calls without pulling out your phone. At 29 g with a rubber enclosure and a flexible, bendable frame, it is designed to sit lightly on your head through a full run.
Who should buy it? Runners, gym-goers, and remote workers who bounce between a laptop and a phone all day. The multipoint connection is the feature I would lean on most: you can take a call on your phone with one click while your laptop's music pauses automatically. The IPX6 rating handles sweat and rain, though MZYDM is explicit that it is not for swimming. Fifteen hours of playtime covers a week of commutes on a single charge.
Who should skip it? If you need a documented fast-charge window, want a specific color beyond black, or plan to swim, look elsewhere. The 2.5 mm jack reference on the sheet is for the wired accessory, not a standard 3.5 mm port, so don't buy it expecting to plug into an older phone or airplane adapter.
The X13 leans hard into the practical stuff. Its 250 mAh battery is rated for 15 hours at 50% volume, and the fast-charge story is the real differentiator: a 10-minute USB-C top-up gives you 2 hours of playback, and a full recharge takes about 1 hour. If you have ever realized your headphones were dead five minutes before a run, that is the spec that saves you. At 28 g (0.99 oz) in an orange polycarbonate and titanium frame, it is marginally lighter than the MZYDM and shaped to wrap around your head securely.
The call quality pitch is concrete. Jutaruoo pairs a 12 x 17 mm bone conduction transducer with a self-developed audio algorithm, dual stereo bass tuning, and ENC digital noise reduction. The company claims the transducer design reduces the vibration sensation you feel against your cheekbones — a genuine comfort issue with bone conduction — and that the mics filter wind and traffic so your voice stays clear. Bluetooth 5.4 delivers a 60 ms latency figure, which is fine for calls, video, and casual gaming, and the 10-meter range is stated plainly. Physical buttons let you change volume and tracks with wet hands, which matters more than it sounds when you are mid-run.
The design details are thoughtful. The open-ear frame is explicitly compatible with safety helmets, glasses, and masks, which makes it a legitimate pick for construction, warehouse, delivery, and cycling work where you must hear your surroundings. Jutaruoo also documents the intentional gap at the neckband — it keeps the vibration units from shifting and avoids collar interference — and answers the multipoint question directly: pair device A, turn off its Bluetooth, select "X13" on device B, then switch A back on, and you are connected to both.
Who should buy it? Cyclists, commuters, shift workers, and anyone who wants fast charging and clear calls over raw driver size. Who should skip it? If you want the widest Bluetooth range or the largest driver in this comparison, the MZYDM edges it. And like its rival, the X13 is IPX6 — rain and heavy sweat, not swimming or submersion.
Side-by-Side: Which Should You Choose?
• Best for battery convenience → Jutaruoo X13. Same 15 hours, but the 10-minute/2-hour fast charge and 1-hour full charge are documented, while MZYDM's charging time is not.
• Best for driver size and audio headroom → MZYDM Bone Conduction Headphones. Its 15 mm bone conduction driver is the larger unit; the X13 lists a 12 x 17 mm transducer.
• Best for call clarity in wind and traffic → Jutaruoo X13. ENC digital noise reduction is a stated feature, and the sheet calls out wind and traffic filtering specifically.
• Best for helmet, glasses, and mask wearers → Jutaruoo X13. Its wrap-around frame is explicitly designed to sit alongside that gear.
• Best for multipoint pairing guidance → Jutaruoo X13. It publishes a step-by-step routine for holding two devices at once; MZYDM confirms multipoint support but leaves the method to you.
• Best for the lightest feel → Jutaruoo X13. 28 g versus MZYDM's 29 g — a hair's difference, but the X13 also claims reduced vibration sensation.
• Best for wired backup → MZYDM Bone Conduction Headphones. It ships with a 2.5 mm jack and a carrying case; the X13 has no jack at all.
If I were buying one, I would take the Jutaruoo X13. In my opinion, the combination of USB-C fast charging, a published multipoint pairing routine, ENC call clarity, and helmet/glasses compatibility makes it the more useful headset for the way most people actually live — short top-ups, constant device switching, and calls taken outdoors. The MZYDM is the better pick if range and driver size top your list, and its 15 mm driver and 15-meter range are genuinely appealing. But for daily reliability, I would reach for the X13.
how to pair multiple headphones
You usually cannot play the same audio through two separate Bluetooth headphones at once unless your device supports dual audio output. What most people mean is switching between two headphones, which just requires pairing each one to your phone or laptop separately and selecting the active device in your Bluetooth menu.
how to pair multiple headphones iphone
On iPhone, open Settings, then Bluetooth, and pair each headset one at a time. The iPhone remembers them, and you switch the active one from the Bluetooth list; simultaneous playback to two headsets is generally not supported on iOS.
how to pair multiple headphones on ipad
The iPad works the same way as the iPhone. Pair each headset individually in Settings > Bluetooth, then tap the one you want to use. For two-device use on the X13, pair device A, turn off its Bluetooth, pair device B as "X13", then switch A back on.
how to pair multiple bluetooth headphones
Pair the first headset, then the second, and confirm both appear in your device's Bluetooth list. For a single headset holding two devices at once — like the MZYDM or X13 — pair the first device, disable its Bluetooth, pair the second, then re-enable the first so both stay connected for seamless switching.
