How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want one pair of open-ear headphones built for outdoor sports with a rear safety light and 10 hours of playtime, choose KLKE Z3; if you need two wearing styles in one case with active noise cancelling and up to 50 hours of total battery, choose Kinglucky 2-in-1.
• KLKE Z3 biggest strength: a purpose-built outdoor sports headset — open-ear bone conduction fit, IP66 sweatproof rating, a rear safety warning light for low-light runs and rides, and dual Indoor/Outdoor sound modes on one button.
• KLKE Z3 biggest trade-off: no active noise cancelling at all (the sheet lists noise control as "None"), and the open-ear design means you'll always hear your surroundings — which is the point, but not what you want on a noisy commute.
• Kinglucky 2-in-1 biggest strength: one charging case holds two completely different earbuds — in-ear with ANC and Transparency, plus open-ear clip-ons for awareness — with relay charging that stretches total playtime to up to 50 hours.
• Kinglucky 2-in-1 biggest trade-off: IPX4 splash resistance only (fine for sweat and light rain, not for heavy outdoor exposure), and the clip-on pair won't give you the same open-ear stability a dedicated sports headband offers.
• Who each pick is for: KLKE Z3 for cyclists, runners, hikers and dog walkers who want awareness plus night visibility; Kinglucky 2-in-1 for commuters and office workers who want to switch between focus and awareness without carrying two sets.
The KLKE Z3 is a single-purpose tool, and it's honest about that. It's an open-ear bone conduction headset with a Bluetooth 5 connection, a 10-meter wireless range, and a 3-hour charge that returns up to 10 hours of playtime. The audio driver is a bone conduction driver paired with what KLKE calls an all-in-one transducer design, which the spec sheet frames around deeper low-frequency performance and clearer voice pickup through the built-in microphone. No jack, all wireless, button controls only.
What it does best is outdoor awareness. The open-ear fit leaves your ear canal unobstructed, so traffic, footsteps and voices come through while your audio plays — exactly the behavior you want on a bike lane or a trail. Two sound modes let you flip between Indoor (balanced clarity) and Outdoor (more bass power) with a single button, which is a small but genuinely useful touch when the environment changes mid-session. The standout detail is the rear safety warning light: a bright orange light on the back of the headband that improves how visible you are at night. For runners, cyclists, hikers and dog walkers, that's a real safety feature, not a gimmick. Add an IP66 rating and a polyurethane build in GreyWhite, and you have a headset designed to be worn hard outdoors.
Buy the KLKE Z3 if you exercise outdoors in traffic, you value being able to hear what's around you, and you ride or run in low light. Skip it if you mainly listen on planes, trains or in open-plan offices and want the world quieted down — there is no noise cancelling here, and the open-ear design is the opposite of isolation. Also skip it if you want a charging case; this is a one-piece headband, not a case-and-buds setup.
The Kinglucky 2-in-1 takes the opposite approach: instead of one form factor done well, it gives you two. The case holds an in-ear pair and an open-ear clip-on pair. The in-ear buds bring active noise cancellation plus a Transparency mode and 13mm dynamic drivers, with a 20Hz–20,000Hz frequency range and 32-ohm impedance. That's the pair you wear when the subway is loud or you need to lock into a podcast. When you want to hear announcements or answer a colleague without pulling anything out, Transparency mode does the job — the awareness feature people hunt for when they search terms like "ambient aware."
The clip-on pair is the comfort option. It sits outside the ear canal, so there's less plugged-in pressure and it's easier to hold a natural conversation while still hearing your audio. Neither pair is built like a rugged sports headband, but the whole set carries IPX4 sweat and splash resistance, which covers commutes, light workouts and drizzly walks. Bluetooth 5.4 keeps the connection stable, and the switch between styles is just a matter of which pair you pull from the case.
The headline feature is relay power. One pair stays in your ears while the other charges in the case; when the battery dips, swap and keep going. Total playtime is listed at up to 50 hours, with a 50-minute charge time. There's also an 18-month support and replacement policy, and the spinning case is a small tactile bonus.
Buy the Kinglucky 2-in-1 if you want both focus and awareness from one purchase, you commute in noisy environments, and you'd rather not carry two separate headsets. Skip it if your priority is serious outdoor sports use — IPX4 isn't built for heavy rain or mud, and the clip-ons won't match a dedicated open-ear sports headband for stability during hard running or cycling.
Side-by-Side: Which Should You Choose?
• Best for outdoor safety → KLKE Z3. The rear warning light plus open-ear awareness is a combination nothing on the Kinglucky sheet replicates.
• Best for noise cancelling → Kinglucky 2-in-1. Active Noise Cancellation is listed on its in-ear pair; KLKE Z3 lists noise control as "None."
• Best for long single sessions → KLKE Z3. Ten hours continuous without swapping anything is simpler than managing two pairs.
• Best for weather and sweat → KLKE Z3. IP66 is a meaningfully tougher rating than IPX4 for sustained outdoor exposure.
• Best for commuting and office use → Kinglucky 2-in-1. ANC for the train, Transparency for the desk, clip-ons for long wear.
• Best for cycling and running → KLKE Z3. Open-ear bone conduction with dual sound modes and a 10-meter Bluetooth range is tuned for movement.
• Best for people who hate in-ear pressure → both, differently. KLKE Z3 avoids the ear canal entirely; Kinglucky gives you a clip-on option when the in-ears feel like too much.
In my opinion, these two don't really compete — they solve different problems. If your listening happens outdoors, on a bike, on a trail or on dark streets, I'd buy the KLKE Z3. The IP66 build, the dual Indoor/Outdoor modes and especially that rear safety light make it the more thoughtfully designed product for that specific job. If your listening happens on trains, in offices and across a long day where you want both silence and awareness on demand, I'd buy the Kinglucky 2-in-1 — two fits in one case with ANC and up to 50 hours is hard to argue with. Check the current price on Amazon for both before deciding, since that's the one variable this comparison can't cover.
what is ambient aware on headphones
Ambient aware (sometimes called Transparency or Aware mode) is a feature that pipes outside sound into your ears on purpose, so you can hear traffic, announcements or a coworker without removing your headphones. On the Kinglucky 2-in-1, this is handled by the in-ear pair's Transparency Mode. The KLKE Z3 achieves a similar awareness effect passively, because its open-ear design never blocks your ear canal in the first place.

I can't speak to Bose controls, and neither product here is a Bose model — but the general logic on any headphone is a dedicated mode button or a cycle through ANC, Transparency and Off. On the Kinglucky 2-in-1, noise control is listed as Active Noise Cancellation, so you'd switch between ANC and Transparency rather than hunting for a separate aware toggle.

Again, this isn't a Bose product, so the exact button sequence doesn't apply. What matters for buyers here is that the Kinglucky 2-in-1 gives you Transparency Mode for on-demand awareness, while the KLKE Z3 gives you awareness by design — there's nothing to turn on, because the open-ear fit always lets sound in.

Not applicable to either of these two models, but the principle is worth knowing: on most headphones, aware or transparency modes are turned off by cycling back to ANC or to a fully passive setting. With the KLKE Z3 there's no aware mode to disable at all — its open-ear bone conduction structure is permanently "aware" by nature.
