• Anker Soundcore Space One — biggest strength: adaptive active noise cancelling plus a 60-hour battery rating and Hi-Res LDAC audio, in a foldable over-ear design.
• Anker Soundcore Space One — biggest trade-off: it seals your ears completely by design, so it's the wrong tool when you need to hear traffic, machinery or a coworker shouting your name.
• E-filliate DEWALT Heavy Duty — biggest strength: an open-ear, air-conduction fit with memory-wire earhooks, IP55 earbuds and physical buttons you can work with gloves on.
• E-filliate DEWALT Heavy Duty — biggest trade-off: no noise cancelling at all, and a 20 Hz–20,000 Hz frequency range that won't reach the Hi-Res heights of the Anker.
• Pick the Anker if your priority is immersive, quiet, high-fidelity listening at your desk or on a plane.
• Pick the DEWALT if your priority is staying alert, secure and hands-free while you're moving or working.
The Space One Pro is built around one idea: shut the world out and give you a big, rich soundstage while you do it. Its 4-stage adaptive ANC senses your surroundings and adjusts cancellation in real time, which is exactly the behavior you want in an airport terminal or an open-plan office where the noise floor keeps changing. The 40 mm triple-composite drivers are Hi-Res certified up to 40 kHz, and if you switch on LDAC in the free soundcore app you get CD-quality wireless streaming instead of the usual compressed Bluetooth stream.
Battery is the other headline. Anker rates it at 40 hours with ANC on and 60 hours with ANC off, and a 5-minute top-up is quoted at 8 hours of playback — enough to rescue a commute when you forgot to charge overnight. The headband self-adjusts without clamping, and the protein leather plus slow-rebound foam ear cushions are aimed at full workdays and long-haul flights. It also folds to roughly half its size, which matters if you're packing a carry-on. Bluetooth 5.3 with multipoint means your phone and laptop can both stay connected and you just switch by playing audio on one or the other.
Who should buy it: commuters, remote workers, students, frequent flyers, and anyone who wants app-based EQ control to tune bass, mids and treble to taste. Who should skip it: cyclists, runners on open roads, and tradespeople who need ambient awareness — the sealed over-ear fit works against you in those settings. It's also a wireless-first design, though there is a 3.5 mm jack and an AUX cable in the box if you want a wired fallback.
The DEWALT Heavy Duty open-ear earbuds take the opposite approach. They use air conduction to push sound toward your ear canal while deliberately leaving your ears open, so you can hear a backing-up forklift, a colleague, or a car behind you on a run. That's the whole point of the design, and it's why the earbuds carry an IP55 water-resistance rating (the charging case is IP44) — sweat, dust and light rain are part of the brief.
The fit is where these earn their keep. Flexible memory-wire earhooks wrapped in soft silicone hook over your ears and hold position without plugging your canals, which is far more stable than a loose bud when you're climbing, lifting or moving around. Audio comes from 18x11 mm dynamic drivers tuned for bass and clarity, and the frequency range runs 20 Hz–20,000 Hz. Controls are physical multifunction buttons rather than touch sensors, so you can hit volume, track and call controls with dirty or gloved hands — a genuinely thoughtful choice for the intended user.
Battery is quoted at 10 hours per charge at 50% volume and up to 44 hours total with the charging case, which covers a long shift plus the ride home. Bluetooth 5.3 is on board with a rated 30-meter wireless range, and the brand backs it with a limited lifetime warranty. Note there's no noise cancelling here — that's not an oversight, it's the trade-off that keeps your ears open.
Who should buy it: contractors, warehouse and shop workers, landscapers, delivery riders, gym-goers and runners who want music without losing situational awareness. Who should skip it: anyone who wants to block out a noisy cabin or wants deep, isolating bass — open-ear acoustics simply can't deliver that.
Side-by-Side: Which Should You Choose?
• Best for noise cancelling → Anker Soundcore Space One. 4-stage adaptive ANC versus none at all on the DEWALT.
• Best for total battery runtime → Anker Soundcore Space One, rated 60 hours with ANC off versus 44 hours including the DEWALT case.
• Best for situational awareness → E-filliate DEWALT Heavy Duty. Open-ear air conduction is the entire design premise.
• Best for audio fidelity and codec support → Anker Soundcore Space One. 20 Hz–40,000 Hz with Hi-Res and LDAC versus 20 Hz–20,000 Hz standard Bluetooth.
• Best for gloved or dirty-hand control → E-filliate DEWALT Heavy Duty. Physical buttons beat touch sensors on a jobsite.
• Best for travel and packing → Anker Soundcore Space One. It folds to roughly half size and includes a carry pouch, USB-C cable and AUX cable.
• Best for workouts and wet conditions → E-filliate DEWALT Heavy Duty. IP55 earbuds and secure memory-wire hooks.
• Best for switching between phone and laptop → Anker Soundcore Space One, thanks to Bluetooth 5.3 multipoint.
In my opinion, these two aren't really competitors — they solve different problems, and the right answer depends entirely on whether you're allowed to block out the world. If I'm buying for commuting, focused desk work, or a long flight, I'd take the Anker Soundcore Space One: adaptive ANC, Hi-Res LDAC, multipoint and a 60-hour battery rating make it the more capable listening device by a wide margin. If I'm buying for a jobsite, a warehouse floor or outdoor training, I'd take the E-filliate DEWALT Heavy Duty without hesitation — open-ear awareness, a secure earhook fit, IP55 protection and glove-friendly buttons are exactly what that environment demands, and no amount of noise cancelling makes up for not hearing a warning shout.
For sound quality and noise isolation, yes — Hi-Res LDAC audio and adaptive ANC are in a different class. For safety and awareness while working or training, no. They're built for opposite use cases.
No. The specs list noise control as "None." That's intentional: open-ear, air-conduction design keeps your ears open to your surroundings, which is the safety feature, not a missing one.
The Anker is rated up to 60 hours with ANC off (40 with ANC on). The DEWALT is quoted at 10 hours per charge and up to 44 hours with its charging case, so the Anker wins on a single charge and the DEWALT wins on portability.
Yes. They include a built-in microphone, Bluetooth 5.3 and physical buttons for call control, so you can take a call without pulling your phone out — handy when your hands are full or gloved.
Both sit in different parts of the market, so it's worth checking the current price on Amazon before deciding. Match the design to your use case first, then compare the live figures.
