If you want serious hearing protection with Bluetooth audio for loud outdoor chores, choose ZOHAN EM037; if you need a lightweight open-ear headset for calls and workouts while staying aware of your surroundings, choose MAIRDI Bone Conduction Headphones. These two products sit in completely different corners of the audio world, which is exactly why the choice comes down to your use case rather than any spec-versus-spec winner.
• ZOHAN EM037's biggest strength: 30dB SNR noise reduction with a 1100mAh battery rated for 40 hours of playtime — this is a Bluetooth earmuff built to muffle loud machinery, not to blend into the background.
• ZOHAN EM037's biggest trade-off: It's a full over-ear earmuff weighing 11.52 ounces, so it's bulkier and heavier than an open-ear band, and the sound-isolation design means it deliberately blocks the world out.
• MAIRDI's biggest strength: A 32g titanium alloy neckband with Bluetooth 5.3, dual-device pairing, AI dual-mic noise cancellation and up to 10 hours of talk time — built for movement and conversation, not for blocking sound.
• MAIRDI's biggest trade-off: Bone conduction sits outside your ear canal, so it provides no meaningful hearing protection and far less battery endurance than the ZOHAN.
• Who each pick is for: ZOHAN EM037 for mowing, snowblowing and any job where ear protection is the point; MAIRDI for running, cycling, hiking, truck driving and remote-work calls where you must hear traffic, coworkers or your kids.
The ZOHAN EM037 is, first and foremost, a piece of hearing protection equipment that happens to have Bluetooth. That framing matters. The 30dB SNR noise reduction comes from a durable ABS shell and double-thickened noise-canceling foam, and the gel ear pads are there to keep the seal comfortable over long sessions. When you're behind a mower or a snowblower, the foam and shell are doing the heavy lifting — the audio is the bonus, not the headline. If you've ever pulled off earmuffs to answer a call and then immediately regretted it because the machine was still running, this design is aimed squarely at that moment.
Who should skip it? Anyone who wants to hear what's happening around them. This is a sound-isolation product by design. If you're running on a road, cycling, or need to stay aware of traffic, kids or a job site radio call, the EM037 works against you — it's built to shut the world out, and that's the whole point. It's also a chunkier item at 11.52 ounces, so if you want something that disappears on your head for hours, this isn't that. And if your main need is clear phone calls, the spec sheet here points to sound isolation, not voice pickup — that's MAIRDI's territory.
MAIRDI Bone Conduction Headphones: Who It's For
MAIRDI takes the opposite philosophy: keep your ears open and deliver sound through bone conduction instead. The 32g titanium alloy neckband is the centerpiece — light enough for all-day wear, with an open-ear shape that stays put during physical activity and is specifically noted to work while wearing a helmet or glasses. That last detail is more useful than it sounds. If you wear prescription glasses or a bike helmet, most over-ear and in-ear options fight with your gear. A band that sits on your cheekbones and wraps behind your neck doesn't.
On the audio side, MAIRDI leans on high-quality transducers and a dedicated bass vocal vibrator to reduce the vibration and sound leakage that bone conduction is famous for. The company frames it as a fix for the classic bone-conduction complaint — thin, buzzy bass. I can't verify how it sounds in person, but the design intent is clear: richer low end and less leakage than typical open-ear bands. For workouts, that's the difference between tolerable and genuinely motivating.
The connectivity and mic package is where MAIRDI pulls ahead for a specific buyer. Bluetooth 5.3 with Qualcomm tech means a stable link and lower power draw, plus the ability to pair with two devices at once — so you can take a call on your phone while staying connected to a laptop. The AI dual-mic noise cancellation is aimed at exactly the people who live on calls in noisy places: truck drivers, remote workers, video meetings, online classes. Up to 10 hours of talk time and 300 hours of standby, with magnetic charging, rounds out a package built for the workday and the trail.
Who should skip it? Anyone who actually needs hearing protection. Bone conduction transmits sound through your skull but does nothing to reduce the 95-plus decibels of a mower or snowblower. If loud machinery is your environment, MAIRDI is the wrong tool — and 10 hours of talk time is a fraction of ZOHAN's 40 hours of playtime, so marathon sessions favor the earmuff.
• Best for hearing protection → ZOHAN EM037. 30dB SNR with double-thickened foam and an ABS shell is the entire point of this product.
• Best for battery life → ZOHAN EM037. 1100mAh and 40 hours of playtime versus MAIRDI's 10 hours of talk time.
• Best for calls and voice clarity → MAIRDI. AI dual-mic noise cancellation and Bluetooth 5.3 with dual-device pairing are built for conversation.
• Best for running, cycling and hiking → MAIRDI. The 32g open-ear band stays secure and keeps you aware of traffic.
• Best for loud chores like mowing and snowblowing → ZOHAN EM037. This is its stated purpose and where the isolation design earns its keep.
• Best for helmet or glasses wearers → MAIRDI. The neckband design is explicitly built to coexist with both.
• Best for all-day light wear → MAIRDI. 32g is a fraction of ZOHAN's 11.52 ounces.
• Best for seasonal, occasional use → ZOHAN EM037. The long playtime means it's charged and ready when you need it, not every week.
If I had to pick one, I'd buy the ZOHAN EM037 — but only because my priority is protecting my hearing during loud outdoor work, and that's the job it's designed for. In my opinion, the 30dB SNR rating, the gel pads and the 40-hour battery make it a genuinely purposeful piece of gear rather than a gadget. That said, if your life involves calls, running or cycling, MAIRDI is the smarter buy, and I wouldn't hesitate to recommend it for that lane. The honest answer is that these aren't competitors so much as two different tools — match the tool to the task and you'll be happy either way. Check the current price on Amazon before you commit, since both sit in different budget tiers.
FAQ
Yes, for mowing specifically. The ZOHAN's 30dB SNR reduction and over-ear foam-and-shell design are meant to block loud engine noise, while bone conduction offers no hearing protection at all. If the machine is loud, the earmuff wins.
No — and that's intentional. The open-ear design leaves your ear canal unobstructed so you can hear traffic, people and surroundings. The AI dual-mic system reduces background noise on your voice during calls, but it doesn't isolate you from the environment.
ZOHAN EM037, by a wide margin. It's rated for 40 hours of playtime from a 1100mAh battery, while MAIRDI is rated for up to 10 hours of talk time and 300 hours of standby. For multi-day use without charging, ZOHAN is the clear pick.
Yes. MAIRDI's 32g titanium alloy neckband is designed to stay secure during activity even when you're wearing a helmet or glasses, which is a common pain point with over-ear and in-ear options.
