How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want three pairs of long-cord wired in-ear earphones you can hand out to a whole streaming or recording setup, choose VizGiz 3; if you need a single pair of wireless open-ear clip-on sports headphones that leave your ears free and your phone in your pocket, choose NUPLEA Open Ear Bone. These two products barely compete for the same buyer — one is a wired, tethered, multi-pack tool for desks and studios, the other is a cable-free, sweat-oriented headphone for running and cycling. The real question is which kind of listener you are.
• VizGiz 3 biggest strength: three wired 3.5mm in-ear headsets with a 3.3-meter cord, a fully enclosed isolating design, and a bundled wire clip and hook-and-loop tie — built for seated, long-distance, multi-person use.
• VizGiz 3 biggest trade-off: it is entirely wired and entirely in-ear, so you are tethered to a jack and cut off from ambient sound — a poor match for running outdoors.
• NUPLEA Open Ear Bone biggest strength: a completely open, clip-on design with Bluetooth wireless, a digital-display charging case, and a 16.2mm vibrating driver that keeps your ears open to traffic and conversation.
• NUPLEA Open Ear Bone biggest trade-off: it is a single unit (not a multi-pack), relies on battery power, and its open design deliberately lets outside noise in rather than blocking it.
• Who VizGiz 3 is for: streamers, webcasters, K-song singers, and anyone recording or monitoring at a computer or phone who wants spares and a long reach.
• Who NUPLEA Open Ear Bone is for: runners, cyclists, gym-goers, and commuters who want music without sealing off the world — and without a cable.
The VizGiz 3 is, first and foremost, a quantity-and-reach product. You get three headsets in the box — one white, one red, one black — each with an in-line 3.5mm plug and a signal line measuring roughly 3.3 meters. That length is the whole point of the design. Sitting at a desk, at a keyboard, or in front of a camera, you are not fighting a short cable that yanks the buds out of your ears every time you lean back. VizGiz explicitly frames this around network K-song sessions and personal computer recording, and the spec sheet backs that up: a long run of cable plus a bundled wire clip you can fasten to your clothing so the cord does not drag or pull.
Comfort is handled the way most in-ears handle it: an ergonomic shape plus multiple sizes of silicone ear tips in the box, so you swap until the seal feels right. The whole set is light — around 24 grams net per unit — and the inline media controller gives you basic playback control without reaching for your device. Small, portable, and three of them.
Who should buy it? The person who needs more than one headset, or who needs one headset that reaches across a desk or a small studio. Three colors means you can assign one per person or keep one as a spare without thinking about it. Who should skip it? Anyone who wants wireless freedom, anyone who dislikes things inside their ears, and — most importantly — anyone who wants to hear traffic while they exercise. This is a stationary, tethered, isolating tool, and it is very good at being that.
NUPLEA Open Ear Bone: Who It's For
The NUPLEA Open Ear Bone takes the opposite philosophy. Nothing goes into your ear canal. The earbuds rest gently on top of your ear in a completely open configuration, and the brand's own framing is that open-ear designs are lighter and more breathable than in-ear headphones, making them more comfortable to wear for long stretches. If you have ever pulled traditional buds out after an hour because your canals felt hot and irritated, this is the design that answers that complaint.
The safety angle is the real selling point, and it is a genuine design consequence rather than a marketing flourish. Because the ear is open, you stay aware of your surroundings. Listening while running or cycling outdoors, you can still register an approaching car or another hazard. That is the single most important reason to pick this style of headphone over an isolating in-ear, and it is why the product is positioned for running, fitness, and exercise.
Battery and wireless freedom carry the rest. On a single full charge the earbuds run about 4 hours, and the charging case adds additional charges up to roughly 48 hours of total playtime from a fully charged case. The case has a smart LED power display that shows remaining battery in real time, so you can see whether the case or the headset needs topping up instead of guessing. The connection is Bluetooth with no jack at all — your phone stays in your pocket or armband.
The sound hardware is notable for the category: 16.2mm vibrating diaphragm drivers, which the brand describes as roughly three times larger than typical wireless earbuds, paired with directional audio technology intended to keep your voice clear on calls. A bone conduction driver is listed as the audio driver type, and the enclosure is plastic in a black finish. Controls are physical push buttons rather than touch — play/pause, track changes, volume, voice assistant, and call answer/hang-up/reject — and the brand specifically notes that buttons prevent accidental touches, which is a real advantage when your hands are sweaty mid-run. There is no active noise control, and that is intentional: this headphone is built to let the world in, not shut it out.
Who should buy it? Runners, cyclists, gym users, and commuters who want music, calls, and awareness at the same time, and who value not having a cable. Who should skip it? Anyone who wants deep isolation for noisy commutes or focused studio monitoring, and anyone who wants multiple headsets rather than one.

If I had to pick one for myself, I would take the NUPLEA Open Ear Bone. In my opinion, the wireless freedom, the open-ear awareness, and the charging case with a visible battery readout make it the more flexible everyday headphone for someone who moves around — and the push-button controls are the right call for anything athletic. But I would only say that if your life involves being outdoors or on the move. If your work is at a desk or in front of a mic, and you want three headsets and a long cable instead of one battery-powered pair, the VizGiz 3 is the smarter buy, and I would recommend it without hesitation for that specific job.
The NUPLEA Open Ear Bone. Its open design keeps your ears free so you can hear traffic and hazards, it has no cable to snag, and the button controls resist accidental touches. The VizGiz 3 is wired and fully sealed, which is the opposite of what outdoor exercise wants.
No — and that is by design. The spec sheet lists no noise control and describes a completely open configuration. They let ambient sound in so you stay aware of your surroundings; that is a safety feature for outdoor use, not a flaw.
Three. The pack includes one headset each in white, red, and black, all with a 3.5mm in-line plug and a cord around 3.3 meters long. That makes it a natural fit for a shared desk, a small studio, or anyone who wants a spare on hand.
The VizGiz 3. Its long cable, clothing clip, sealed isolating design, and the fact that you get three units make it the more practical choice for seated recording, monitoring, and K-song sessions where you do not want to think about charging.
