How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want adaptive noise cancelling with up to 70 hours of battery life in a lightweight on-ear design, choose JBL Tune 670NC; if you need open-ear earbuds that keep you aware of your surroundings on a noisy jobsite, choose E-filliate DEWALT Heavy Duty.
• JBL Tune 670NC — biggest strength: Adaptive Noise Cancelling with Smart Ambient plus JBL Pure Bass Sound, in a foldable on-ear headphone rated for up to 70 hours of battery life.
• JBL Tune 670NC — biggest trade-off: It's an on-ear headphone, so it seals and surrounds your ear instead of leaving it open — the opposite of what you want if you need to hear traffic, machines or co-workers.
• E-filliate DEWALT Heavy Duty — biggest strength: Air-conduction open-ear design with IP55 water resistance on the earbuds, memory-wire earhooks and physical buttons you can work with gloves on.
• E-filliate DEWALT Heavy Duty — biggest trade-off: No noise cancelling at all, and the per-charge runtime is 10 hours, so it's built for shifts and workouts rather than multi-day listening.
• Pick JBL Tune 670NC if you want to block the world out — commuting, studying, long flights, all-day music.
• Pick E-filliate DEWALT Heavy Duty if you want the world kept in — job sites, outdoor work, running and gym sessions where awareness matters.
The JBL Tune 670NC is an on-ear wireless headphone built around two ideas: quiet and low end. Adaptive Noise Cancelling does the first job, and the JBL Headphones app gives you Ambient Aware and TalkThru modes so you can sharpen surrounding sound or voices without pulling the headphones off your head. That combination is the whole point of this model — you get to decide how much of the world reaches you, from a button press or a voice command.
The second idea is JBL Pure Bass Sound, delivered through 32-ohm dynamic drivers with a 20 Hz – 20 kHz frequency range and 98 dB sensitivity. Bluetooth 5.3 with LE Audio handles the wireless side, and the app's Smart Audio & Video feature lets you bias the connection toward sound quality or toward lower-latency video and gaming output. Battery figures are the headline: up to 70 hours average life, up to 44 hours with Bluetooth on and ANC off, a full charge in about 2 hours over USB-C, and a 5-minute top-up that buys you roughly 3 more hours. At 174 g with soft ear cushions and a padded headband, it's light enough for long sessions, and the foldable design plus included detachable audio cable and carrying case make it a travel-friendly package.
Buy it if you're a commuter, student, traveller or home listener who wants noise cancelling, deep bass and marathon battery life from one pair of headphones.
Skip it if you work in a loud, safety-sensitive environment where you must stay aware of your surroundings, or if you simply dislike anything pressing on your ears. This is a closed, on-ear headphone with a plastic build and a 2-year warranty — it's a listening tool, not a piece of jobsite gear.
The E-filliate DEWALT Heavy Duty is the opposite philosophy in a much smaller package. These are true wireless open-ear earbuds using air-conduction technology: the driver aims sound toward your ear canal while your ear stays open, so surrounding noise comes in. DEWALT frames it as a jobsite-safety feature, and that's exactly how it behaves. The earbuds carry an IP55 water-resistance rating and the charging case is rated IP44, so sweat, dust and light rain aren't a problem. The 18 x 11 mm dynamic drivers are sized to push bass and clarity even when the environment around you is loud — a smart bit of engineering for open-ear buds, because open designs normally lose low end first.
Fit is handled by flexible memory-wire earhooks wrapped in soft silicone that conform to your ear shape, which is what keeps open earbuds stable during movement. Controls are physical multifunction buttons for volume, tracks and calls — a real advantage when your hands are dirty or gloved, since there are no touch sensors to fight with. Battery is rated at 10 hours per charge at 50% volume and up to 44 hours total with the charging case. Bluetooth 5.3 is on board with a stated range of up to 30 meters, there's a built-in microphone for calls, and the whole thing is backed by a limited lifetime warranty. Weight is 0.14 kg including the case, and the colourway is black and yellow.
Buy it if you work outdoors or on job sites, run, cycle, lift or train, and want music without giving up awareness of what's happening around you — or if you want gloves-on button control.
Skip it if you want silence. There is no noise cancelling here, no audio jack, and 10 hours per charge is a shift-length figure, not a week-long one. For a quiet flight or a focused study session, this is the wrong tool.
• Best for noise cancelling → JBL Tune 670NC. Adaptive Noise Cancelling with Smart Ambient is its core feature; the DEWALT has none.
• Best for total battery life → JBL Tune 670NC. Up to 70 hours average life and up to 44 hours with Bluetooth on and ANC off, versus 10 hours per charge and up to 44 hours total on the DEWALT.
• Best for staying aware of your surroundings → E-filliate DEWALT Heavy Duty. Open-ear air conduction keeps your ears unblocked by design.
• Best for workouts and movement → E-filliate DEWALT Heavy Duty. Memory-wire silicone earhooks and an open fit hold up better than an on-ear headphone when you're moving.
• Best for dusty, sweaty or wet conditions → E-filliate DEWALT Heavy Duty. IP55 on the earbuds and IP44 on the case; the JBL sheet lists no water-resistance rating.
• Best for gloved or messy hands → E-filliate DEWALT Heavy Duty. Physical multifunction buttons beat touch controls when your hands aren't clean.
• Best for travel and long listening sessions → JBL Tune 670NC. 174 g, foldable, padded headband, carrying case, detachable audio cable and fast USB-C charging.
• Best for calls in both worlds → a tie. The JBL has VoiceAware and voice/button control with Google Assistant and Siri; the DEWALT has a built-in mic and one-button call control.
• Best for gaming and video → JBL Tune 670NC. The app's Smart Audio & Video mode lets you favour video latency over pure audio quality.
In my opinion, the JBL Tune 670NC is the better buy for most people, because adaptive noise cancelling, JBL Pure Bass Sound and up to 70 hours of battery life cover far more of everyday life — commuting, studying, flights, working from home. I'd only steer you to the E-filliate DEWALT Heavy Duty if awareness is non-negotiable: job sites, road running, cycling or any environment where hearing what's around you is a safety requirement rather than a preference. Those are genuinely different jobs, and each product does its own job well. Check the current price on Amazon before deciding, since that's the one variable that can tip a close call.
FAQ
No. Its noise-control field is listed as none — the open-ear air-conduction design deliberately lets outside sound in. The JBL Tune 670NC is the one with Adaptive Noise Cancelling and Smart Ambient modes.
The JBL Tune 670NC is rated up to 70 hours average life, and up to 44 hours with Bluetooth on and ANC off, with a 2-hour charge time. The DEWALT is rated 10 hours per charge at 50% volume and up to 44 hours total with its charging case.
Yes — that's what they're built for. The memory-wire earhooks keep them stable, the earbuds are IP55 water resistant, and the physical buttons work with gloves or sweaty hands. Just remember they don't block background noise.
