How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want to stay aware of traffic, hear your surroundings, and keep your ears open while you train, choose Puro Sound Labs; if you need to block out loud machinery and power tools on a job site while you work, choose ASHATA Earplug Headphones. Both pair over Bluetooth 5.3 and both carry an IPX5 water-resistance rating, so neither one is the weak link on sweat or rain. The real fork in the road is what you want your ears to do: stay open, or get sealed shut.
• Puro Sound Labs biggest strength: Bone conduction drivers sit on your cheekbones and leave your ear canals completely open, so you hear music and the world around you at the same time — plus a 6-hour battery and magnetic charging.
• Puro Sound Labs biggest trade-off: 6 hours of playback is modest, and there's no noise cancellation at all. Open ears mean you hear everything, including the stuff you didn't want to hear.
• ASHATA Earplug Headphones biggest strength: 29dB of passive noise reduction with over 20 hours of playback from a 200mAh battery, and a 10-minute charge gets you 2 hours back.
• ASHATA Earplug Headphones biggest trade-off: The whole point is blocking sound, so you lose situational awareness. In-ear silicone plugs also aren't for everyone over a full shift.
• Choose Puro Sound Labs if you run, ride, or work out near traffic and want to stay alert.
• Choose ASHATA Earplug Headphones if you're around machinery, power tools, or loud workshops and need the noise gone.
The PuroFree is a bone conduction headphone, and that single design choice drives everything else. Instead of pushing sound into your ear canal through a tip or a cup, it vibrates against your cheekbones and lets your inner ear do the rest. Your canals stay open. On a run, that means you hear the car behind you, the cyclist calling out, the dog, the crossing signal. For outdoor fitness, that's the entire appeal — and it's why I'd point most runners and cyclists here first.
The build supports that use case. The frame is silicone-wrapped, lightweight, and shaped to stay put through movement rather than clamp down like a traditional sport headphone. It's rated IPX5, which covers sweat, splashes, and rain — exactly what an outdoor workout throws at you. Bluetooth 5.3 keeps the wireless link steady for music and calls, and there's a built-in mic, so taking a call mid-session is realistic. Charging is magnetic, which is a small thing that matters more than people expect when you're sweaty and rushing out the door. Battery life is rated at 6 hours, with a 2-hour charge time.
Where it falls short: 6 hours is a single long workout or a couple of shorter ones, not a week of commuting. There's no noise control listed — none — and that's by design, not an oversight. If you want to disappear into a mix on a noisy train, this isn't the tool. And because the drivers sit outside your canal, bass won't hit the way a sealed in-ear will. In my opinion, this is the right pick for the runner, the cyclist, the outdoor athlete, or the parent who wants to stay tuned in to their surroundings. Skip it if your goal is silence.
The ASHATA is the opposite philosophy executed well. It's an in-ear earplug headphone built around a neckband, and its headline feature is 29dB of noise reduction. That's not active noise cancellation — it's the physical kind, from a three-layer silicone earplug that seals your canal. The result is that machinery hum, saw whine, and power-tool racket get knocked down before they ever reach your ears. If you spend your day on a construction site, in a workshop, or around landscaping equipment, that's the reason to buy.
The neckband design is smarter than it looks. It's low-profile, so it can sit under a collar or protective clothing with only the earbuds showing — practical when you're wearing a hard hat, welding gear, or coveralls. The battery is the other standout: a 200mAh cell rated for over 20 hours, which comfortably covers a full shift or more, and a 10-minute top-up gets you 2 hours of playback when you're caught short. Bluetooth 5.3 gives fast pairing and a stable connection up to about 33 feet, and it works with both iOS and Android. The IPX5 rating means damp, splashes, sweat, and light rain are all fine — the manufacturer lists welding, woodworking, landscaping, running, yard work, and farming as fits.
The trade-off is baked in. Sealed ears mean you don't hear what's around you, and 29dB of blocking is a lot to give up if you're near traffic or need to hear a coworker call out. The ABS build is functional rather than refined, and it's a 90-day manufacturer warranty versus a full year on the Puro. I'd recommend this for tradespeople, workshop users, and anyone who wants to work through noise rather than around it. Skip it if situational awareness is non-negotiable.
• Best for staying aware of surroundings → Puro Sound Labs. Open-ear bone conduction is the whole point.
• Best for blocking loud machinery → ASHATA Earplug Headphones. 29dB of passive noise reduction with a sealed in-ear fit.
• Best for battery life → ASHATA Earplug Headphones. Over 20 hours from a 200mAh battery versus 6 hours on the Puro.
• Best for quick top-ups → ASHATA Earplug Headphones. A 10-minute charge yields 2 hours of playback.
• Best for running and cycling outdoors → Puro Sound Labs. IPX5 plus open ears is the safer combination near traffic.
• Best for job sites, workshops, and yard work → ASHATA Earplug Headphones. It's built for industrial and outdoor labor environments.
• Best for comfort over a long shift under gear → ASHATA Earplug Headphones. The low neckband tucks under a collar or protective clothing.
• Best for a lightweight, secure fit during movement → Puro Sound Labs. The silicone-wrapped frame is designed to stay put without clamping.
If I had to pick one, I'd buy the Puro Sound Labs PuroFree — but only because my use case is outdoor movement, and the open-ear design is the feature I can't substitute. For running, cycling, and training near traffic, hearing my surroundings matters more than bass or battery. That said, if your day revolves around loud machinery, I'd flip without hesitation: the ASHATA's 29dB of noise reduction and 20-plus-hour battery are the two things the Puro simply cannot match, and no amount of open-ear design makes up for that in a workshop. Match the product to your environment and you'll be happy either way — and if budget is the deciding factor, check the current price on Amazon before you commit.
FAQ
are headphones waterproof
are headphones water resistant
These two are. IPX5 is a water-resistance rating, and both products list it, so sweat during a workout, light rain on a run, or splashes on a job site are all within spec. Just don't confuse water resistance with waterproofing — the distinction matters if you plan to get them truly wet.
The ASHATA Earplug Headphones, clearly. It lists 29dB of noise reduction via sealed three-layer silicone earplugs, and its whole purpose is blocking machinery and power-tool noise. The Puro Sound Labs PuroFree lists no noise control at all, because its open-ear bone conduction design is meant to let sound in.
ASHATA, by a wide margin. The ASHATA is rated for over 20 hours from a 200mAh battery and can gain 2 hours of playback from a 10-minute charge. The Puro Sound Labs PuroFree is rated at up to 6 hours per charge with a 2-hour charge time.
