How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want true wireless freedom with active noise cancellation and all-day battery from a case, choose Sudio A3; if you need open-ear awareness and a wired connection that never needs charging, choose LQZM Bone Conduction Headphones. These two are barely in the same category — one is a sealed in-ear ANC earbud, the other is a wired bone-conduction sports headphone that leaves your ear canal completely open. That difference decides everything below.
• Sudio A3 biggest strength: Active Noise Cancellation rated at 18dB plus Bluetooth 5.4 multipoint, so you can pair a phone and a laptop at the same time and shut out the room around you.
• Sudio A3 biggest trade-off: 5 hours per charge (25 hours total with the case) means it's a battery you have to manage, and the sealed in-ear fit blocks out exactly the sounds the LQZM is built to let in.
• LQZM biggest strength: Bone conduction keeps your ear canal open, so traffic, bells and voices stay audible — and it's wired over Type-C, so there's no battery to run down at all.
• LQZM biggest trade-off: No microphone listed, no noise control, and a wired cable tethering you to your device. This is a workout tool, not a call tool.
• Who each pick is for: Sudio A3 for commuters, remote workers and anyone who wants calls and focus; LQZM for runners, cyclists and riders who need to hear the world while they train.
The Sudio A3 is a sealed in-ear earbud built around two ideas: quiet and connection. The 18dB Active Noise Cancellation is the headline. It's not the deepest ANC on the market, but it's enough to take the edge off a bus engine, an open-plan office or a plane cabin so you can actually hear your podcast. Pair that with Bluetooth 5.4 multipoint and you get something genuinely useful — your phone stays connected while your laptop is connected too, and you can jump between a work call and your music without re-pairing anything.
Battery is where you need to be honest with yourself. Five hours per charge, stretched to 25 hours total with the case, is a full-day-of-listening figure if you're disciplined about dropping them back in the case. It is not a "forget to charge for three days" figure. The 5-hour charge time is on the long side, so this is a pair you top up overnight rather than in a panic.
Where it earns its place is calls and focus. The enhanced microphones are designed to keep your voice clear in noisy rooms, and the IPX4 rating means sweat and splashes won't kill them — fine for the gym or a rainy walk, not for swimming. The design details matter too: a frosted Scandinavian look, geometric stems, and 20% recycled plastics in the build, which is a real consideration if you care where your electronics come from. Buy the Sudio A3 if you take calls, want noise cancelled, and value wireless convenience with a case. Skip it if you run or cycle near traffic and need your ears open — the sealed ANC fit is the opposite of what you want there.
The LQZM is a fundamentally different product, and that's the point. It uses bone conduction to send audio through your cheekbone instead of into your ear canal. Nothing enters your ear. That means you hear your music and the world at the same time — traffic approaching, a bell ringing, a colleague saying your name. For running, cycling, climbing or gym work, that's a safety feature, not a gimmick.
The fit is the other half of the story. It's a hanging-ear design with an elastic band that adjusts to your head circumference, and at 16Ω impedance with a 42dB/mW sensitivity rating, it's easy to drive — the kind of load a phone's Type-C output handles without strain. The frequency range is listed at 130–15000Hz, which tells you something concrete: bass below 130Hz simply isn't part of the picture. If you want thump, this isn't the tool. If you want spoken-word, podcasts and steady training music, it's fine.
Two things you should know before buying. First, it's wired over Type-C — no battery, no charging, no pairing, but also a cable running to your device. Second, the spec sheet lists no microphone ("with or without microphone: None") even though the product name mentions one, so don't buy this expecting to take calls. Buy the LQZM if you train outdoors and want your ears open, or you have sensitive ears that dislike in-ear tips. Skip it if you need calls, noise cancellation or deep bass.
• Best for noise cancellation → Sudio A3. The 18dB ANC actively reduces what you hear; the LQZM lists no noise control at all.
• Best for staying aware of traffic and surroundings → LQZM. Open-ear bone conduction keeps your canal clear by design.
• Best for calls → Sudio A3. Enhanced mics and multipoint Bluetooth 5.4; the LQZM's spec sheet lists no microphone.
• Best for battery freedom → LQZM. It's wired over Type-C, so there's nothing to charge. The Sudio A3 gives you 5 hours per charge, 25 hours with the case.
• Best for deep bass → Sudio A3. The LQZM's 130Hz low end is a hard floor; the Sudio's balanced armature driver targets a fuller sealed sound.
• Best for workouts and sweat → both, with a caveat. Both are IPX4, but the LQZM's open design suits running and cycling better, while the Sudio's sealed fit suits gym and indoor training.
• Best for two devices at once → Sudio A3. Bluetooth 5.4 multipoint handles phone plus laptop; the LQZM connects to one wired source.
• Best for sensitive ears → LQZM. Nothing enters the ear canal, which is the whole reason people choose bone conduction.
In my opinion, most people shopping this comparison should buy the Sudio A3. It does more of what a daily headphone needs to do — noise cancellation, calls, multipoint pairing, a case that keeps it charged — and it fits the commute, the office and the gym. I'd only steer you to the LQZM Bone Conduction Headphones if your priority is outdoor training safety and you can live with a cable and no microphone. That's a real use case, just a narrower one. Check the current price on Amazon before deciding, since the value math shifts between these two very different products.
FAQ
The spec sheet lists "with or without microphone: None," even though the product title mentions a mic. Treat these as music-and-awareness headphones for workouts, not as a calling headset.
Five hours per charge, with up to 25 hours total using the charging case. Full charge time is listed at 5 hours, so plan on topping them up overnight.
The Sudio A3, in my opinion. Its balanced armature driver in a sealed in-ear fit produces fuller low end, while the LQZM's frequency range starts at 130Hz, so deep bass isn't part of its design.
