How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want marathon battery life and a rugged neckband that stays put on a loud jobsite, choose E-filliate DEWALT Heavy Duty; if you need one pair of earbuds that flips between open-ear awareness and active noise cancelling for runs, calls and commutes, choose Anker Soundcore AeroFit 2.
• E-filliate DEWALT Heavy Duty — biggest strength: A 2-in-1 neckband with built-in upward-firing speakers plus earbuds, 60+ hours of earbud runtime, IP56 sealing and a heavy-duty build aimed at the worksite.
• E-filliate DEWALT Heavy Duty — biggest trade-off: It's a neckband, not a pocketable case design, so it lives around your neck rather than in your pocket, and there's no active noise cancelling here.
• Anker Soundcore AeroFit 2 — biggest strength: Dual-mode open-ear and semi-in-ear ANC, 11.8mm drivers with Hi-Res and LDAC, 360° spatial audio with head tracking, and a drop-in charging case.
• Anker Soundcore AeroFit 2 — biggest trade-off: Battery per charge is far shorter — up to 7 hours open-ear and 5 hours with ANC — and the fit depends on your ear shape, with a 16mm ear-diameter guideline.
• Who the E-filliate DEWALT Heavy Duty is for: Tradespeople and outdoor workers who want all-day sound and a speaker mode they can share without taking anything off.
• Who the Anker Soundcore AeroFit 2 is for: Runners, commuters and office workers who want one pair that switches between staying aware and shutting the world out.
The E-filliate DEWALT Heavy Duty is built around one idea: you should never have to take it off. It's a neckband headset, so the electronics sit on your collarbone instead of in a case, and the earphones themselves are tethered with built-in magnets that snap them together when you're not listening. That's a genuinely useful detail on a ladder or under a hood — nothing to lose, nothing to dig for. The headline trick is the 2-in-1 design: the band houses speakers that project audio upward, so you can flip from private earbuds to an outward speaker without swapping devices.
On durability, the numbers point the right direction: IP56 water resistance, a plastic enclosure in DEWALT yellow and black, and a carry pouch in the box alongside ear cushions, ear fins and a Type-C cable. It's rated water resistant rather than fully waterproof, so sweat and rain spray are fine but don't go swimming with it. Who should skip it? Anyone who wants true noise cancelling, a tiny pocketable case, or a headset they can wear lying back on a pillow — the neckband format and the sound leakage from speaker mode are the trade-offs you're accepting. If your day is loud, dirty and long, this is the one that matches it.
Anker Soundcore AeroFit 2: Who It's For
The Anker Soundcore AeroFit 2 is the opposite philosophy: adapt to the moment rather than commit to one format. It's an open-ear hook design, so the driver sits outside your ear canal — no pressure, no plugging, and you keep hearing traffic, coworkers and your surroundings. Then, when you need focus, it switches to semi-in-ear active noise cancelling to cut down everyday noise in a gym, an office or on a train. One pair, two jobs, and you don't carry a second set of headphones to cover the gap.
The audio hardware is the spec-sheet highlight. 11.8mm dynamic drivers, Hi-Res Audio and LDAC support, plus 360° spatial audio with dynamic head tracking, so the sound stage follows your head movement. Four microphones with AI-assisted call clarity handle the talking side. The hooks are adjustable, the materials mix PC, ABS, silica gel and titanium, and the charging case is deliberately roomy — it accepts the buds in all five hook positions, so you just drop them in without resetting the angle first. That's a small thing that becomes a big thing after the fiftieth time you charge them.
Battery is the compromise to understand before you buy. Anker quotes up to 7 hours per charge in open-ear mode (34 hours with the case) or 5 hours in ANC mode (24 hours total), and with LDAC on you're looking at roughly 6 hours open-ear or 3 hours with ANC. A 10-minute top-up adds about 3.5 hours. That's a day of listening, not a work week. Fit is also personal: the design targets people with an ear diameter over 16mm. If your ears are small or the hook shape doesn't sit right, this isn't the pair for you. For runners, commuters and hybrid workers who charge nightly anyway, none of that is a dealbreaker.
• Best for battery life → E-filliate DEWALT Heavy Duty. 60+ hours of earbud runtime versus 7 hours per charge on the AeroFit 2.
• Best for noise cancelling → Anker Soundcore AeroFit 2. It's the only one of the two with active noise cancellation.
• Best for jobsite and outdoor work → E-filliate DEWALT Heavy Duty. IP56 sealing, heavy-duty construction and a neckband that can't fall out of your ears.
• Best for running and cycling → Anker Soundcore AeroFit 2. Open-ear hooks keep you aware of traffic, and the adjustable hook fit is made for movement.
• Best for sharing audio with someone nearby → E-filliate DEWALT Heavy Duty. The upward-firing speakers turn it into a wearable speaker.
• Best for sound quality features → Anker Soundcore AeroFit 2. 11.8mm drivers, Hi-Res Audio, LDAC and 360° spatial audio with head tracking.
• Best for calls in a noisy office → Anker Soundcore AeroFit 2. Four mics with AI-assisted clarity and ANC to reduce background noise.
• Best for all-day comfort with nothing in your ear canal → Anker Soundcore AeroFit 2. Liquid silicone open-ear design, roughly 3.84 ounces total.
• Best if you hate charging daily → E-filliate DEWALT Heavy Duty. Charge it once and forget it for days.
In my opinion, the E-filliate DEWALT Heavy Duty is the one I'd buy if my listening happens at work, outdoors or in long stretches where charging is a hassle — 60+ hours, IP56, and a wearable speaker mode are hard to argue with. I'd pick the Anker Soundcore AeroFit 2 instead if my day is a mix of runs, calls and commutes and I want one pair that shifts between awareness and noise cancelling. If you truly can't decide, ask yourself which you'd miss more: a week of battery, or the ability to silence a noisy room. That answer picks your pair.
FAQ
Yes. It's a dual-mode design: open-ear when you want to hear your surroundings, and semi-in-ear active noise cancelling when you want to block out everyday noise. The DEWALT neckband has no ANC at all — it relies on its format and fit instead.
The DEWALT is rated for 60+ hours of earbud playback and 7.5+ hours of speaker time. The AeroFit 2 gives up to 7 hours per charge in open-ear mode (34 hours with the case) or 5 hours in ANC mode, dropping to roughly 6 or 3 hours with LDAC enabled.
Anker says it's designed for a comfortable, secure fit for most people with an ear diameter over 16mm, and offers a 30-day money-back guarantee if it doesn't work out. The DEWALT neckband sidesteps the fit question entirely because the earphones hang from the band rather than relying on an in-ear seal.
