How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a feature-packed open-ear pair with app-style customization, adjustable hooks and a charging case that stretches total playtime to 36 hours, choose Anker Soundcore V20i; if you need the lightest possible open-ear headset for long conference calls and all-day wear, choose CXK Open Ear Headphones.
• Anker Soundcore V20i — biggest strength: 16mm dynamic drivers with BassUp, four adjustable hook positions, four mics with AI call enhancement, multipoint Bluetooth 5.4, IP55, and a charging case that takes total listening time to 36 hours.
• Anker Soundcore V20i — biggest trade-off: The buds themselves are the heavier, bulkier option here, and the extra features (lights, touch controls, case) mean more to learn and more to carry.
• CXK Open Ear Headphones — biggest strength: A 23g lightweight build (per the manufacturer's spec) with a 210° rotatable boom mic, quick triple-press mute, dual-mic noise reduction and 12 hours of playtime — a headset-first design.
• CXK Open Ear Headphones — biggest trade-off: No charging case, no stated IP rating, push-button plus touch controls that take practice, and a smaller 15mm driver than the V20i.
• Pick the V20i if you want richer sound, situational awareness on the move, and case-based battery life.
• Pick the CXK if you want the lightest possible thing on your ears for calls, coaching cues and podcasts.
The V20i is built around one idea: stay aware of your surroundings without giving up sound quality. The open-ear hook design leaves your ear canal open, so traffic, voices and ambient noise still reach you. That's the whole point of open ear headphones, and Anker leans into it with a non-intrusive fit the brand describes as comfortable enough for all-day wear.
What makes it stand out on paper is the tuning and the battery story. The 16mm dynamic drivers use titanium-coated domes plus Anker's BassUp technology, which is the brand's way of pushing bass in an earbud that by design can't seal your ear. Four adjustable hook positions let you rotate the bud to find a stable spot, which matters if you wear glasses or have ears that usually reject hooks. Four mics with an AI algorithm handle calls, and Bluetooth 5.4 with multipoint means you can stay connected to a laptop and a phone at once. The IP55 rating is the practical detail most open-ear buyers forget until it rains or they sweat through a run.
Battery is split between the buds and the case: roughly 8 hours in the earbuds and up to 36 hours total with the case, which charges in about 2.5 hours while the buds recharge in about 1.5. There's also a customizable light feature that pulses with your music — a nice touch if you want your gear to look like gear, and easy to ignore if you don't.
Buy it if: you want open-ear awareness plus real bass, you move between phone and laptop all day, and you want a case that keeps everything topped up. Skip it if: you want the absolute lightest headset, you dislike touch controls, or you need a boom mic that sits right at your mouth.
The CXK takes a different route. Instead of a lifestyle earbud that happens to take calls, this reads as a headset that happens to play music. The headline number is weight: 23g, which is the kind of figure that disappears on your head after a few minutes. If you've ever taken an open-ear pair off after a two-hour call and felt relief, that spec is the one you care about.
Audio is handled by a 15mm dynamic driver using air conduction rather than bone conduction. CXK claims that approach gives better bass than bone conduction designs, along with clear mids and highs that suit podcasts, voice prompts and coaching cues — the mid-forward stuff where speech intelligibility beats thump. Impedance is listed at 12 ohm, so it should be easy to drive from a phone or laptop.
The call side is where the CXK earns its place. Dual microphones with noise reduction filter background sound, and there's a 210° rotatable microphone you can swing toward your mouth. Muting is a triple-press of the "-" button with a voice prompt confirming "Mute On" or "Mute Off", which is genuinely useful when you're on a call and someone walks in. Playtime is listed at 12 hours, and Bluetooth 5.4 with a stated 33-foot range covers a normal room or a walk away from your desk.
Buy it if: you live on calls, want the lightest possible open-ear fit, and value a rotatable boom mic and one-touch mute. Skip it if: you want a charging case, an IP rating for sweat and rain, or the bigger driver and app-style extras of the V20i.
• Best for sound quality → Anker Soundcore V20i. A 16mm driver with BassUp outranks a 15mm driver on paper, and Anker's tuning is aimed squarely at bass.
• Best for all-day lightness → CXK Open Ear Headphones. 23g is the number to beat if weight is what makes you take headphones off.
• Best for calls → CXK Open Ear Headphones. Dual mics, noise reduction, a 210° rotatable mic and a dedicated mute command are all call-first features.
• Best for battery life → Anker Soundcore V20i. Up to 36 hours total with the case versus 12 hours on the CXK.
• Best for sweaty or wet conditions → Anker Soundcore V20i. IP55 is the only water/dust rating stated between the two.
• Best for switching between devices → Anker Soundcore V20i. Multipoint Bluetooth 5.4 lets you hold two connections at once.
• Best for touch-free, tactile control → CXK Open Ear Headphones. Physical buttons plus touch give you something to press without looking.
• Best for a single, simple headset → CXK Open Ear Headphones. No case to charge, no lights to configure, just put it on and go.
In my opinion, the Anker Soundcore V20i is the better buy for most people. The 16mm drivers with BassUp, four adjustable hook positions, IP55, multipoint and up to 36 hours with the case cover more of what open-ear buyers actually do — commute, run, work, listen. The CXK is the smarter pick only if lightness and call clarity are your top two priorities, because 23g and a rotatable boom mic are genuinely hard to argue with for desk work. If you're still unsure, check the current price on Amazon for both and let your budget break the tie.
