How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want serious passive noise blocking for loud, constant environments like mowing, woodworking or a noisy shop floor, choose 3M Pro-Grade Earmuff; if you need to keep your ears open for traffic, teammates or your own music while you move, choose sunshot Ows Open Ear. These two products barely belong in the same category, and that's exactly why the choice is easy once you know what you're actually solving for.
• 3M Pro-Grade Earmuff — biggest strength: Real over-the-head sound isolation. This is a purpose-built hearing protector, not a gadget. It physically blocks noise instead of trying to cancel or pipe around it.
• 3M Pro-Grade Earmuff — biggest trade-off: It's a one-trick pony. No Bluetooth, no mic, no music. If you want to hear anything other than silence, this is the wrong tool.
• sunshot Ows Open Ear — biggest strength: Open-ear Bluetooth audio with a 16 mm dynamic driver, 40 hours of playtime and IPX5 water resistance, so you get music and calls while staying aware of your surroundings.
• sunshot Ows Open Ear — biggest trade-off: An open, ventilated design lets sound in. It reduces noise, it does not seal it out the way a muff does.
• Who the 3M Pro-Grade Earmuff is for: Anyone whose main problem is loud noise they want gone — workshops, yard work, ranges, industrial settings.
• Who the sunshot Ows Open Ear is for: Runners, cyclists, gym-goers, drivers and commuters who want audio without plugging their ears.
The 3M Pro-Grade Earmuff is a hearing protector first and everything else second. The design is over-the-head with a rubber headband and a black finish, and the noise control method is listed simply as sound isolation. That phrase tells you the whole philosophy: this product blocks sound by putting a physical barrier between your ears and the noise source. There's no battery to charge, no pairing to fumble with, no firmware to update. You put it on and the world gets quieter.
Who should skip it? Honestly, most casual listeners. There is no Bluetooth, no microphone and no audio playback of any kind here. If your goal is to listen to a podcast on a run or take a call on your bike, this product does nothing for you. It's also the wrong pick if you need to stay aware of your surroundings — sound isolation is the point, and that cuts both ways. And if you want something you can tuck in a pocket, this isn't it. This is a wear-it-while-you-work item, not an everyday carry.
In my opinion, the 3M Pro-Grade Earmuff makes the most sense for someone who already knows they have a noise problem and wants the simplest possible fix. Fewer features, fewer failure points.
sunshot Ows Open Ear: Who It's For
The sunshot Ows Open Ear is the opposite approach. Instead of sealing noise out, it sits around the ear and leaves your ear canal open. The earpiece shape is "around the ear," the enclosure is silicone, and the whole thing is built to be lightweight and stable during movement. The design brief is awareness: you can hear your music and still hear a car approaching, a training partner calling your name, or a coworker asking a question without pulling anything out of your ears.
The audio hardware is more serious than the open-ear form factor might suggest. You get a 16 mm dynamic driver, a frequency range of 20 Hz to 20,000 Hz, and 32 ohm impedance — numbers that point to a full-range, easy-to-drive sound rather than a tinny bone-conduction whisper. Sunshot pairs that with Bluetooth 5.4 for a stable, low-latency connection, and 40 hours of playtime so charging isn't a daily ritual. Touch controls on each earbud handle play/pause, volume, calls and voice assistant activation, so you're not digging for your phone mid-run.
Durability and convenience are clearly part of the pitch too. IPX5 water resistance covers sweat and light rain, and the kit includes a charging case, cable and a carry rope you can loop around your wrist if you're wearing something without pockets. Noise reduction is listed as adaptive noise cancellation, which on an open-ear design is best understood as call and background-noise processing rather than the kind of blocking a sealed muff provides.
Who should skip it? If your priority is maximum noise reduction in a genuinely loud environment, this is not the answer. An open, ventilated design lets sound in by definition. And if you want zero charging, zero pairing and zero touch gestures, the simplicity of a passive muff will beat this every time. But for runners, cyclists, gym users, drivers and anyone who wants audio without isolating themselves, the feature list lines up neatly.
• Best for blocking loud, constant noise → 3M Pro-Grade Earmuff. Sound isolation is its entire purpose.
• Best for listening to music or taking calls → sunshot Ows Open Ear. Bluetooth 5.4, a 16 mm dynamic driver and a built-in mic.
• Best for staying aware of traffic and people around you → sunshot Ows Open Ear. The open, ventilated design is built for exactly that.
• Best for zero maintenance → 3M Pro-Grade Earmuff. No battery, no charging, no pairing.
• Best for long sessions away from a charger → sunshot Ows Open Ear. Up to 40 hours of playtime.
• Best for sweaty workouts and light rain → sunshot Ows Open Ear. IPX5 water resistance and silicone construction.
• Best for workshop, yard and industrial use → 3M Pro-Grade Earmuff. The over-the-head fit and protection-focused build suit it.
• Best for someone who wants one simple solution and no learning curve → 3M Pro-Grade Earmuff. Touch controls and voice assistants are not for everyone.
If I had to pick one for myself, I'd buy the sunshot Ows Open Ear. In my opinion it does more jobs well: music, calls, workouts, commuting and everyday wear, all with your ears still open to the world. The 3M Pro-Grade Earmuff is excellent at the one thing it does, and if your days involve loud machinery, that single job might matter more than everything else. But for most people reading a comparison like this, the open-ear buds will get used far more often — and a product you actually wear beats a product that sits in a drawer. Check the current price on Amazon before you commit, since that's the one variable I can't judge for you.
FAQ

No. It has no Bluetooth, no microphone and no audio playback. It's a dedicated hearing protector focused on sound isolation.
Up to 40 hours of playtime on a charge, with a charging case included. That's a big practical advantage if you don't want to plug in every day.
