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 earmuffs that does double duty as hearing protection and a Bluetooth music/call headset for loud chores and workshop days, choose PROHEAR 037; if you need tiny in-ear buds that cancel noise so you can actually sleep, focus or fly in peace, choose Kinglucky 50dB.
• PROHEAR 037 — biggest strength: over-ear hearing protection (SNR 25dB) combined with Bluetooth 6.0 audio and up to 120 hours of playback from a 1100mAh battery. The trade-off: it's a bulky over-ear muff, not something you'd wear lying on your side in bed.
• Kinglucky 50dB — biggest strength: a 50dB hybrid noise-cancelling system (silicone tips + AI frequency splitting + ANC) in 3.0g in-ear buds built for side sleepers, with 60 sleep sounds and three listening modes. The trade-off: it isolates passively and actively rather than blocking sound with a physical over-ear shell, and it's aimed at rest and focus, not power-tool work.
• Who PROHEAR 037 is for: anyone running mowers, saws, snowblowers or loud equipment who wants ear protection and music/calls in one wearable.
• Who Kinglucky 50dB is for: light sleepers, side sleepers, frequent travellers and focused workers who want a quiet bubble in their ears, not on their head.
• The core difference in one line: PROHEAR protects your ears from your environment; Kinglucky removes your environment so you can rest.
The 037 is a hearing-protection headphone first. Its job is to sit over your ears and knock down loud, sustained noise — the spec sheet lists an SNR of 25dB, which is the kind of reduction that makes a running mower or a circular saw noticeably less punishing. What makes it more than a basic muff is the gel cushion design: a silicon gel, memory foam and ultra-thin polyurethane skin sandwich instead of plain foam. In my opinion that's the smartest part of the whole product, because the biggest reason people rip off ear protection mid-job is pressure and heat, and gel pads are built to spread that load and wipe clean.
Who should buy it: homeowners with big yards, woodworkers, landscapers, snowblower owners, anyone who spends hours in genuinely loud environments and wants music or podcasts along the way. The included leather bag and 11.52-ounce build also make it easy to toss in a truck or toolbox. Who should skip it: side sleepers, people who want something invisible in their ears at the office, and anyone who finds over-ear muffs hot or claustrophobic. It's also not a discreet device — people will see you wearing it.
Kinglucky 50dB: Who It's For
The Kinglucky 50dB attacks noise from the opposite direction. Instead of a shell over your ears, it uses triple-layer reduction: soft silicone tips physically block sound like traditional earplugs, AI separates incoming noise by frequency, and active noise cancellation handles the rest. The result is a claimed 50dB peak reduction — the kind of jump that turns a noisy café into something library-quiet. The buds themselves are in-ear, weigh just 3.0g, and use a contoured, ultra-soft silicone contact surface explicitly shaped for side sleepers. If you've ever woken up with sore ears from a normal earbud, that design choice is the entire point.
The feature set is built around sleep and focus rather than job-site protection. There are three modes: Sleep Mode (notifications off, nothing but rest), ANC Focus Mode for work or study, and Transparency Mode so you can hear what's going on around you without pulling the buds out. The app adds 60 tuned sleep sounds — rain, waves, wind — and lets you save three favourites for one-tap playback, plus a timer so playback doesn't run all night. Battery is a USB-C affair: about 1.5 hours to full, roughly 7 hours per charge in the buds and 50 hours total with the case, with an LED display showing remaining power for both. Bluetooth 6.0 keeps the connection steady, and the buds carry a water-resistance rating.
Who should buy it: light sleepers, people who share a bed with a snorer, side sleepers, frequent flyers, shift workers and students who need to disappear into a task. Who should skip it: anyone who needs certified hearing protection around power tools or machinery — these are consumer earbuds, not a safety muff — and anyone who dislikes things sitting inside their ear canal.
• Best for lawn mowing, sawing and workshop noise → PROHEAR 037. Over-ear SNR 25dB protection plus music is exactly the combo it was designed for.
• Best for falling asleep and staying asleep → Kinglucky 50dB. Sleep Mode, 60 sounds, a timer and a side-sleeper-focused fit put it clearly ahead for rest.
• Best for long battery life → PROHEAR 037. Up to 120 hours of playtime, plus unlimited listening via the 3.5mm cable when the battery runs out.
• Best for travel and commuting → Kinglucky 50dB. ANC, Transparency Mode and a charging case make it the easier companion on a plane or train.
• Best for wearing with gloves or in dusty conditions → PROHEAR 037. Raised control buttons you can find by feel, wipe-clean gel pads and a leather carry bag.
• Best for shared bedrooms and noisy neighbours → Kinglucky 50dB. Hybrid cancellation plus physical silicone blocking is aimed squarely at sleep disruption.
• Best all-day comfort on your head (not in your ears) → PROHEAR 037. Gel, memory foam and polyurethane pads are made to reduce pressure over long sessions.
• Best for unobtrusive, in-ear listening → Kinglucky 50dB. 3.0g buds you can forget you're wearing.
If I had to pick one, I'd buy the PROHEAR 037. In my opinion it solves a bigger and more specific problem for more people: protecting your hearing around genuinely dangerous noise levels while still letting you enjoy music or take a call. The gel pads, glove-friendly controls, 120-hour battery and cable backup all point to a product designed by people who've actually spent a long day with a mower. The Kinglucky 50dB is excellent at what it does — I'd recommend it without hesitation to a light sleeper or a side sleeper — but it's a rest-and-focus device, not a safety one. If your loud problem happens at night in bed, flip my answer and get the Kinglucky.
FAQ
It's an over-ear muff measuring roughly 5 x 3 x 6 inches with a rigid ABS shell, so it isn't built for lying on a pillow. For sleep, the Kinglucky's 3.0g in-ear design is the far more sensible pick.
PROHEAR 037 is way ahead: up to 120 hours from a 1100mAh battery, plus cable listening if it dies. Kinglucky gives about 7 hours per charge and 50 hours total with the case, which is normal for true wireless earbuds.
I'd lean PROHEAR 037 if your "work" is loud outdoor or shop tasks, since it doubles as real hearing protection. If your priority is flights, commutes and quiet focus, the Kinglucky's ANC and Transparency Mode are more useful. Check the current price on Amazon for both before deciding, since the value call depends on what you're paying.
