How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a pair of open-ear buds that can hop between your phone and laptop while you train, choose Kinglucky True; if you need a headset with a rotatable boom mic that makes you sound clear on calls all day, choose Blue Air Open Ear.
• Kinglucky True's biggest strength: true wireless open-ear buds with Bluetooth 5.3, multipoint connection, an 18.7mm dynamic driver, and a charging case that stretches 8 hours of playtime into a claimed 60 hours.
• Kinglucky True's biggest trade-off: it is a pair of buds, not a headset — no boom mic, and the mics live in the earpieces, so call clarity depends on the ENC processing rather than a mic you can aim.
• Blue Air Open Ear's biggest strength: a single 34g silicone headset with a 270° rotatable boom mic, AI noise cancellation on calls, a one-click mute button, and multipoint pairing between two devices.
• Blue Air Open Ear's biggest trade-off: Bluetooth 5.1 with a 10-meter range, and the noise cancellation applies to calls only — it is not a music-focused listening device.
• Who Kinglucky True is for: runners, gym-goers and commuters who want lightweight open-ear buds with a big battery case and easy phone-to-laptop switching.
• Who Blue Air Open Ear is for: people on calls all day — remote workers, students in online classes, and anyone who wants a boom mic and a mute button within reach.
Kinglucky True is built around the open-ear bud idea: a soft silicone hook that hangs over the ear instead of plugging the canal. At roughly 7.3g per earbud, the design is meant to spread pressure across the ear rather than press into it, which matters if you wear buds for a full workout or a long commute. The "owls hanging" shape is the stability story here — the hook is what keeps them on when you are moving, and it is also what lets you hear traffic and surroundings while music plays.
The audio side is where the spec sheet gets interesting. Kinglucky uses an 18.7mm racetrack-shaped dynamic driver with a motor coil it claims is 35% larger than conventional ones, covering a 20Hz–20kHz range at 16 ohm impedance. In plain terms, that is a bigger driver than most open-ear buds carry, and the design intent is clear highs, steady mids and real bass — the three things open-ear buds usually struggle with. Dual-mic ENC handles calls, and adaptive noise cancellation is listed for the audio side.
Buy it if you want open-ear buds that disappear on your ears, last through a week of workouts, and switch between your phone and laptop without re-pairing. Skip it if your priority is being heard clearly on long conference calls — there is no boom mic here, and if you want a mic you can position, this is not that product.
Blue Air Open Ear: Who It's For
Blue Air Open Ear takes the opposite approach: instead of two independent buds, it is one 34g headset with a skin-friendly silicone frame and an open-ear design that sits outside the canal. That single-piece build is the whole point. Nothing to lose, nothing to pair left-and-right, and it plays nicely with glasses, hats and helmets — a real consideration for cyclists and anyone who works outdoors.
The headline feature is the 270° rotatable boom mic paired with AI noise cancellation that Blue Air says blocks 99% of background noise on calls. That is a call-first design: Zoom meetings, online classes, client calls. There is also a one-click mute button for instant privacy, which is the kind of thing you only appreciate once you have fumbled for mute mid-meeting. Sound comes from a 16mm dynamic driver over 20Hz–20kHz at 16 ohm — smaller than the Kinglucky driver, and tuned for voice-forward listening rather than critical music sessions.
Battery sits at 8–10 hours of talk or music time, with a 10-minute quick charge giving about an hour and a full recharge in 1.5 hours. Connectivity is Bluetooth 5.1 with multipoint pairing for two devices at once, so you can move between phone and computer without dropping a call. One thing to note: the listed range is 10 meters, so this is a stay-near-your-desk headset, not a wander-the-house one. The controls are physical push buttons rather than touch, which some people strongly prefer — buttons you can feel without looking beat swipe gestures when you are mid-call.
Buy it if you live in meetings, want a boom mic you can angle toward your mouth, and value a mute button you can hit blind. Skip it if you want separate buds for running, or you care most about music quality and long-range freedom — the driver is smaller and the range is shorter than the Kinglucky's.
• Best for multipoint pairing across phone and laptop → both, but Kinglucky True uses the newer Bluetooth 5.3, while Blue Air Open Ear uses Bluetooth 5.1. Either way, you get two-device switching.
• Best for call quality and meetings → Blue Air Open Ear. The 270° rotatable boom mic, AI noise cancellation on calls, and one-click mute are built for exactly this.
• Best for battery life → Kinglucky True. 8 hours per charge and up to 60 hours with the case beats the Blue Air's 8–10 hours with no case.
• Best for running, gym and sweaty workouts → Kinglucky True. IPX5 water resistance, 7.3g per bud, and a hook design made to stay put.
• Best for cyclists, glasses wearers and helmet users → Blue Air Open Ear. The 34g silicone frame is designed to coexist with glasses, hats and helmets.
• Best for wireless range → Kinglucky True. The spec sheet lists 100 meters versus 10 meters for the Blue Air.
• Best for bigger drivers and bass → Kinglucky True. 18.7mm versus 16mm, with a larger motor coil.
• Best for button controls over touch → Blue Air Open Ear. Physical push buttons and a dedicated mute key.
• Best for wearing all day without a case to manage → Blue Air Open Ear. One piece, nothing to charge separately or lose.
In my opinion, the right pick comes down to one question: are you buying for your ears or for your voice? If you are a runner, gym person or commuter who wants open-ear buds with a huge battery case, IPX5 sweat resistance and Bluetooth 5.3 multipoint, I would buy the Kinglucky True. If you spend your day on Zoom, in online classes or on client calls and need a rotatable boom mic with a mute button, I would buy the Blue Air Open Ear. For a pure work-and-calls use case, the Blue Air is the more purpose-built tool. For everything else — training, commuting, music on the move — the Kinglucky True's bigger driver, longer battery and longer range make it my choice.
how to pair multiple headphones
You do not pair several headphones to each other — you pair each headset to your device separately. Both the Kinglucky True and the Blue Air Open Ear support multipoint, meaning one headset can hold connections to two devices at once, like a phone and a laptop, and switch between them.
how to pair multiple headphones iphone
On an iPhone, open Bluetooth settings and connect the headset as usual. With a multipoint model like the Kinglucky True (Bluetooth 5.3) or Blue Air Open Ear (Bluetooth 5.1), you then connect the second device — such as a laptop — and the headset remembers both, letting you move audio between them without re-pairing.
how to pair multiple headphones on ipad
The process is the same as on iPhone: pair the headset in the iPad's Bluetooth menu, then pair your second device. Multipoint support is what makes this work — both headsets here list two-device connection, so the iPad and your phone can stay linked at the same time.
how to pair multiple bluetooth headphones
If you mean using two headsets at once on one device, that depends on the device, not the headset — most phones and laptops output to one audio device at a time. What these two products do offer is multipoint: one headset, two connected devices, with switching between them.
