If you want serious hearing protection with music and calls on the job, choose PROHEAR 037; if you need waterproof, open-ear audio for swimming and sweaty outdoor training, choose viyawise B11.
• PROHEAR 037 — biggest strength: SNR 30dB passive noise reduction paired with Bluetooth 6.0 and up to 120 hours of playtime from a 1100mAh battery. It's a hearing protector first, headphones second.
• PROHEAR 037 — biggest trade-off: It's an over-ear muff weighing 11.52 ounces with an ABS plastic build. You wear it; you don't forget it's there. And it is not waterproof.
• viyawise B11 — biggest strength: IP68 waterproofing rated for 2 meters of water for up to 2 hours, plus 32GB of built-in MP3 storage so you can swim with zero connection. It weighs only 28 grams.
• viyawise B11 — biggest trade-off: Bluetooth does not work underwater — you must switch to MP3 mode. Battery life is 10 hours per charge, and noise control is Environmental Noise Cancellation, not hearing protection.
• For loud-jobsite protection → PROHEAR 037.
• For swimming, running and cycling → viyawise B11.
The PROHEAR 037 is built around one job: keeping loud noise out of your ears while letting you stay entertained and reachable. The SNR 30dB rating is the headline number here. That's real attenuation, the kind that matters when you're running a mower, a snowblower, a table saw, or a leaf blower for an afternoon. The over-ear, sound-isolation design is what delivers it, and that design choice explains almost everything else about the product.
Around that core, PROHEAR wraps in Bluetooth 6.0 with a stated wireless range of 80 feet. The pitch is a more stable connection than older Bluetooth versions, so your phone can stay in your pocket while you work across a yard or shop floor. The 1100mAh rechargeable lithium battery is rated for up to 120 hours of playtime, and it charges over the included cable — no disposable batteries to hunt for. There's also a 3.5mm connector for wired listening when you want it.
The controls are worth calling out for anyone who works with gloves on. PROHEAR uses a raised tactile bump so you can find the buttons by feel, then adjust volume, skip tracks, and answer or end calls without pulling the muffs off. The headband is adjustable and the ear pads are soft and breathable, which is the difference between tolerating a muff for twenty minutes and wearing it all morning. The package includes a black leather bag to keep dust off between jobs.
Who should buy it: homeowners and tradespeople doing building, lawn mowing, woodworking, landscaping, or snowblowing who want one device that protects hearing and plays audio. Adults, one-size over-ear fit. Who should skip it: swimmers, anyone who wants open-ear awareness of traffic while running, and anyone who can't tolerate 11.52 ounces on their head for long stretches.
The viyawise B11 solves the opposite problem. It's an open-ear, bone-conduction headphone that sits outside your ear canal, so you get audio without plugging your ears — and, critically, you stay aware of what's happening around you. For runners, cyclists, and hikers sharing space with cars and other people, that awareness is the whole point. The open-ear earpiece shape and 28-gram weight mean it largely disappears on your head, and the silicone and TPE enclosure is built to flex with movement rather than clamp down.
The waterproofing is the standout spec. IP68 is a serious rating, and viyawise states it can be submerged in 2 meters of water for up to 2 hours. That covers swimming laps as well as sweat and rain during sport. The catch is important: Bluetooth doesn't transmit through water, so you switch to MP3 mode underwater. That's exactly why the 32GB of built-in storage exists — it holds up to 8,000 songs, and you load them by connecting the magnetic charging cable to a computer and copying files over like a USB drive. Double-click to toggle between Bluetooth and MP3.
Above water, Bluetooth 6.0 handles wireless audio and can stay connected to two devices at once — phone and laptop, for example. A noise-suppressing microphone is included for calls, and viyawise claims clear call quality in noisy environments. Battery life is up to 10 hours of music, calls, and podcasts per charge, with a full charge in about 2 hours via magnetic charging. The audio side uses a bone conduction driver with an 8-ohm impedance and a 20Hz–20,000Hz frequency range. The package includes the headphones, magnetic charging cable, earplugs, and a user manual, with 24/7 after-sales support and a 30-day return and refund window.
Who should buy it: swimmers, runners, cyclists, and gym-goers who want audio without blocked ears. Adults and teens. Who should skip it: anyone who needs actual noise reduction at a worksite — this is not a hearing protector — and anyone who wants bass-forward, sealed in-ear sound.
• Best for hearing protection → PROHEAR 037. SNR 30dB with over-ear sound isolation. The B11 offers no hearing protection at all.
• Best for underwater use → viyawise B11. IP68, 2 meters for up to 2 hours, with 32GB of offline MP3 storage.
• Best for long battery life → PROHEAR 037. Up to 120 hours of playtime versus 10 hours on the B11.
• Best for all-day comfort and low weight → viyawise B11. 28 grams and an open-ear fit against 11.52 ounces of over-ear muff.
• Best for staying aware of traffic and surroundings → viyawise B11. Open-ear bone conduction leaves your ear canal unobstructed.
• Best for gloved, hands-free control on a job → PROHEAR 037. The raised button bump lets you adjust audio without removing the muffs.
• Best for carrying music without a phone → viyawise B11. 32GB of onboard storage and USB transfer; the PROHEAR relies on Bluetooth or its 3.5mm cable.
• Best for dual-device multitasking → viyawise B11. It can hold two Bluetooth connections at once.
If I had to pick one, I'd buy the PROHEAR 037 — but only because my priority would be protecting my hearing while I work, and nothing on the B11 does that job. The SNR 30dB rating, the 120-hour battery, and the glove-friendly controls make it the more capable tool for mowing, woodworking, and shop noise.
That said, if your noise problem is water and traffic rather than decibels, the B11 is the smarter buy. IP68 plus 32GB of MP3 storage is a combination built for swimmers, and 28 grams of open-ear design is built for runners. Different jobs, different tools.
The PROHEAR 037. Its SNR 30dB over-ear design is made for loud equipment noise, and the 120-hour battery covers many sessions between charges. The B11 provides no hearing protection.
Yes, within limits. It's IP68 rated for submersion in 2 meters of water for up to 2 hours. You must switch to MP3 mode while underwater, because Bluetooth won't transmit through water.
No, and they work differently. The B11 uses Environmental Noise Cancellation, which targets background noise for calls and awareness. The PROHEAR 037 uses passive sound isolation to physically block loud noise.
The PROHEAR 037, on battery alone — up to 120 hours per charge from its 1100mAh battery versus up to 10 hours on the B11. For price, check the current price on Amazon for both before deciding.
