If you want proven noise-cancelling performance with the longest single-charge stamina and a featherweight fit, choose Anker Soundcore; if you need a touchscreen charging case, an IPX7 waterproof build and call-focused ENC for workouts and commutes, choose ZYHKON Earbuds.
• Anker Soundcore — biggest strength: an auto-adjusting ANC system that adapts to your surroundings, plus up to 50 hours of total playtime with 10 hours from a single charge.
• Anker Soundcore — biggest trade-off: it's a renewed unit with a 90-day limited warranty, and it relies on app-based control rather than an on-case screen.
• ZYHKON Earbuds — biggest strength: a smart touchscreen charging case that lets you control volume, tracks, calls, ANC and alarms without touching your phone, backed by IPX7 waterproofing and a 24-month warranty.
• ZYHKON Earbuds — biggest trade-off: shorter battery life (6–8 hours per charge, up to 48 hours total) and a less aggressive 38dB ANC rating than Soundcore's advertised 98% noise reduction.
• Who each pick is for: Soundcore suits frequent flyers and long-shift listeners who want set-and-forget noise cancelling; ZYHKON suits gym-goers, runners and touchscreen-first users who want phone-free control and sweat resistance.
The Space A40 is built around one idea: take the thinking out of noise cancelling. Its upgraded ANC system is rated to reduce noise by up to 98%, and it does this automatically — the earbuds detect what's around you and dial the cancellation level up or down. Indoors, outdoors, on a commute, on a flight. You don't fiddle with settings; the earbuds do the adjusting. That's a genuinely useful design choice for anyone who moves between loud and quiet environments all day.
Battery is the other headline. You get 10 hours from a single charge and up to 50 hours total with the case — the kind of stamina that lets you commute and work for a couple of weeks before you think about plugging in. A 10-minute top-up buys you roughly 4 hours of listening, which is the difference between a silent train ride and a boring one. The 10mm double-layer diaphragm drivers handle the sound, with strong bass, clear mids and bright treble, and LDAC mode is there if you want Hi-Res Audio Wireless from a compatible source.
Comfort gets real attention too. These are described as smaller than all other Soundcore ANC earbuds and light as a sheet of paper, with an ergonomic in-ear shape meant to avoid fatigue over long sessions. In my opinion, this is the pair to buy if your priority is cancelling noise for hours at a time without babysitting a settings menu. Skip it if you specifically want on-case controls, want to swim or train hard in the rain, or you'd rather have a longer warranty than a 90-day limited one.
ZYHKON takes the opposite approach: put the controls where your hands already are. The Z9pro's charging case has a smart touchscreen that shows real-time battery levels for both the buds and the case, and lets you adjust volume, skip tracks, answer calls, toggle ANC or Transparency Mode, set alarms and even locate your earbuds — all without pulling out your phone. For anyone who hates digging a phone out on a packed train or mid-run, that's a genuinely practical design decision rather than a gimmick.
Noise handling is split between two systems. Hybrid ANC cuts up to 38dB of ambient noise, while ENC filters out roughly 90% of background voices on calls. That combination is aimed squarely at the "noisy subway, crowded café, open office" crowd — you want the music clean and your voice clear when you speak. Transparency Mode flips you back to hearing the world when you need it.
On the audio side, 14.2mm dynamic drivers push deep bass, balanced mids and crisp highs, and there are 5 EQ modes — Standard, Rock, Jazz, Pop and Classic — switchable straight from the case with no app required. Battery runs 6–8 hours per charge and up to 48 hours total with the case. The build is IPX7 waterproof, so sweat, rain and splashes are fine, and three sizes of silicone tips (S/M/L) help you find a secure fit. Bluetooth 5.4 handles pairing and stability, and ZYHKON backs it with a 24-month warranty. Skip it if maximum noise cancellation depth or marathon single-charge battery is your top priority.
• Best for noise cancellation depth → Anker Soundcore. Up to 98% reduction with automatic adjustment versus ZYHKON's 38dB hybrid ANC.
• Best for single-charge battery life → Anker Soundcore. 10 hours per charge and 50 hours total, versus 6–8 hours and 48 hours total.
• Best for fast top-ups → Anker Soundcore. A 10-minute charge yields about 4 hours of listening.
• Best for phone-free control → ZYHKON Earbuds. The touchscreen case handles volume, tracks, calls, ANC, alarms and earbud locating.
• Best for workouts and wet weather → ZYHKON Earbuds. IPX7 waterproofing is the clear edge over a standard in-ear plastic build.
• Best for call clarity in loud places → ZYHKON Earbuds. ENC is rated to filter about 90% of background voices.
• Best for switching sound profiles on the fly → ZYHKON Earbuds. 5 EQ modes changeable from the case, no app needed.
• Best for Hi-Res wireless audio and app tuning → Anker Soundcore. LDAC mode and app-based customization.
• Best for long-term peace of mind → ZYHKON Earbuds. A 24-month warranty versus 90 days limited, and it's a new unit rather than renewed.
If I were buying for myself, I'd take the Anker Soundcore Space A40. The auto-adjusting ANC and the 10-hour-per-charge, 50-hour-total battery are the two things I'd actually feel every single day, and the lightweight in-ear design is built for long sessions. I'd only switch to the ZYHKON Earbuds if the touchscreen case, IPX7 waterproofing and 24-month warranty matter more to me than raw cancellation depth — which, for a gym-goer or a runner, they genuinely might. Both are solid; pick based on whether you want the best cancelling or the smartest case.
FAQ
Soundcore gives 10 hours per charge and up to 50 hours with the case, plus about 4 hours from a 10-minute charge. ZYHKON gives 6–8 hours per charge and up to 48 hours total, with real-time battery levels shown on the case screen.
Yes. They carry IPX7 waterproofing, so sweat, rain and splashes are covered, and they ship with three silicone tip sizes for a secure fit. The Soundcore pair isn't rated for that kind of exposure.
That depends on what you value. Soundcore wins on cancellation and battery; ZYHKON wins on the touchscreen case, IPX7 rating, 5 EQ modes and a 24-month warranty. Check the current price on Amazon for each before deciding.
