How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want an open-ear fit that keeps you aware of traffic, your training partner and the world around you, choose Purity Air Open Ear; if you need real active noise canceling and marathon battery life for long days and long trips, choose FIFINE X3W.
• Purity Air Open Ear — biggest strength: a neckband open-ear design with 15 mm drivers, dual mics and IPX5 sweat resistance, built for movement and situational awareness.
• Purity Air Open Ear — biggest trade-off: 6 hours of battery life, no noise canceling, and a neckband shape that not everyone loves.
• FIFINE X3W — biggest strength: active noise canceling, 65 hours of playtime, Bluetooth 5.3 with multi-point, and a 3.5 mm wired option.
• FIFINE X3W — biggest trade-off: it's over-ear and sealed, so you lose the open, aware feeling, and it's the heavier of the two.
• Who each is for: Purity Air Open Ear for runners, cyclists and outdoor listeners; FIFINE X3W for commuters, travelers, office workers and anyone who wants to disappear into their audio.
The Purity Air Open Ear is built around one clear idea: sound that reaches your ears without plugging them up. It uses air conduction with two 15 mm dynamic drivers, a 20 Hz–20,000 Hz range and 18 ohm impedance. In practice, that means you hear your music and the environment at the same time — a genuinely different listening experience from anything sealed.
The design is a neckband that hangs behind your neck with speakers resting against your ears, in a white and lilac finish. At 2.8 ounces it's light, and the open-ear placement means no pressure building up inside your ear canal over a long session. It's rated IPX5 for sweat and water resistance, which is why the theme here is sports. For running, cycling, or gym work where you want to hear a car, a coach or a teammate, this is the natural fit. Dual microphones handle calls with ambient noise cancellation, and you control things with touch buttons. Bluetooth 5.3 gives you a 10-metre range.
Battery life is the honest limitation: 6 hours per charge, with a magnetic charging cable that connects to the right speaker. That's a session's worth, not a week's worth. Buy it if you train outdoors, hate the plugged-up feeling of earbuds, and want to stay aware. Skip it if you need all-day battery, want to block out a noisy commute, or simply don't get along with neckband designs.
The FIFINE X3W goes the opposite direction entirely. It's an over-ear headphone with active noise canceling, and that single feature reshapes who it's for. The ANC is designed to cut through subway rumble, office chatter and crowd noise so you can focus on music or a call. If your listening happens in loud places, this is the tool for the job.
The numbers back up the "long haul" positioning: 65 hours of playtime, a 2.5-hour recharge, and Bluetooth 5.3 with multi-point so you can stay connected to two devices at once and jump between a call and a video meeting without re-pairing. There's also a 3.5 mm jack, which is a genuinely useful fallback when you want a wired connection. Sound is handled by dynamic drivers with a 20 Hz–20,000 Hz range and 32 ohm impedance, tuned for detail and clarity rather than raw volume. Touch controls sit on the earcup.
Comfort is addressed with a soft, adjustable, stretchable headband and light cushions. That said, it's an over-ear headphone at 0.49 kg — noticeably heavier than the Purity, so comfort over a very long stretch is something to weigh up. There's no IP rating in the specs, so I wouldn't treat it as a sweat-heavy workout headphone. Buy it if you travel, commute, work in open offices, or want one pair that survives a multi-day trip on a single charge. Skip it if you need to hear your surroundings or want the lightest possible fit.
• Best for situational awareness → Purity Air Open Ear. The open-ear neckband lets ambient sound in by design.
• Best for blocking out noise → FIFINE X3W. Active noise canceling is the core feature here.
• Best for battery life → FIFINE X3W. 65 hours versus 6 hours is not a close call.
• Best for running, cycling and sweaty workouts → Purity Air Open Ear. IPX5 plus a secure open-ear fit.
• Best for commuting, flights and office work → FIFINE X3W. ANC, multi-point and a wired option.
• Best for all-day wearing comfort → Purity Air Open Ear. 2.8 ounces and nothing inside your ear canal.
• Best for calls in noisy places → FIFINE X3W. Sealed cups plus ANC isolate your voice better than an open design.
• Best for a single pair that does everything → FIFINE X3W, unless staying aware matters more to you than isolation.
If I had to pick one, I'd buy the FIFINE X3W. In my opinion, it's the more versatile headphone: active noise canceling, 65 hours of playtime, multi-point Bluetooth 5.3 and a 3.5 mm wired fallback cover far more of my day than an open-ear design can. The Purity Air Open Ear is excellent at exactly one thing — keeping you aware while you move — and if that's your priority, it's the better buy. For everyone else, the FIFINE is the safer, broader choice. Check the current price on Amazon before deciding, since that's the one variable I can't speak to here.
Not necessarily. The Purity has IPX5 sweat resistance and an open-ear fit that keeps you aware of traffic, which suits outdoor running. The FIFINE has no listed water-resistance rating and is heavier, so I'd lean Purity for sport.
The FIFINE X3W is rated at 65 hours per charge with a 2.5-hour recharge time. The Purity Air Open Ear is rated at 6 hours. For multi-day use without charging, the FIFINE wins comfortably.
No. It has dual microphones with ambient noise cancellation for calls, but no active noise canceling for your music. The FIFINE X3W does have active noise canceling.
The FIFINE X3W, in my view. Multi-point connectivity and sealed over-ear cups with ANC make it easier to stay focused and be heard on calls, especially in noisy rooms.
