How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want maximum isolation in a tiny, wired-only in-ear monitor built for critical listening, choose erjigo KZ ZS10; if you need hybrid active noise cancellation, 60-hour battery life, and the freedom to go wireless or wired, choose Anker Soundcore Life Q20.
• erjigo KZ ZS10 — biggest strength: A five-driver hybrid setup (4 balanced armatures + 1 dynamic driver per side) with a 7Hz–40kHz range and a metal-resin body that isolates noise up to 26dB passively.
• erjigo KZ ZS10 — biggest trade-off: It's wired-only by default (the detachable 2-Pin cable allows upgrades, but no Bluetooth is included) and it's an in-ear monitor, so it won't give you active noise cancellation.
• Anker Soundcore Life Q20 — biggest strength: Hybrid active noise cancellation with 4 microphones, BassUp processing, and up to 60 hours of playtime in standard mode.
• Anker Soundcore Life Q20 — biggest trade-off: It's an over-ear headphone that relies on battery for ANC, and its tuning leans toward bass emphasis rather than flat monitoring.
• Who the KZ ZS10 is for: Listeners, musicians, and gamers who want wired, isolating, detail-forward sound in a compact IEM.
• Who the Life Q20 is for: Commuters, travelers, and office workers who want one pair of headphones that handles noise, calls, and long trips.
The KZ ZS10 is a wired in-ear monitor, and everything about it points at that purpose. Each side packs four balanced armatures (two for highs, two for mids) plus a 10mm dual-magnetic dynamic driver, which together cover a claimed frequency range of 7Hz to 40000Hz. That's an unusually wide spread for an IEM, and it's the kind of spec that tells you the designers cared about extension at both ends — deep lows from the dynamic driver, articulate mids and crisp highs from the armatures. With 111dB sensitivity and 24 ohms impedance, it's efficient enough to run off a phone or a laptop jack without demanding a dedicated amp.
The isolation here is passive, not active. The cavity is shaped around cochlea data for a secure fit, and the design is rated to block up to 26dB of external noise. In practice, that means a properly sealed tip cuts down a lot of consistent background drone — a bus engine, an air conditioner, a noisy café — without any electronics involved. It's not adaptive, and it won't react to changing environments the way ANC does, but it also never runs out of anything and never needs charging.
Build is a genuine selling point. The faceplate is 304 stainless steel in a sand-black finish, paired with an imported resin cavity, so it feels more substantial than the average plastic IEM. The detachable 0.75mm 2-Pin cable is gold-plated with a limit-slot design meant to prevent pin breakage, and because it detaches, you can swap cables or eventually add a Bluetooth module. There's a built-in HD mic with one-key control for calls and track skipping, three sizes of ear tips in the box, and a 3.5mm jack with roughly 4.1 feet of cable. It weighs about 0.07 pounds and comes in purple, black, or blue.
Buy it if you want a wired, noise-isolating monitor for focused listening, stage or studio use, gaming chat, or online meetings — and you're fine with a cable. Skip it if you mainly listen while moving through unpredictable noise, want active cancellation, or refuse to deal with a wire. It's also worth noting the fit is critical: an IEM only isolates well when the tip seals properly.
The Life Q20 takes the opposite approach. It's a wireless over-ear headphone that also accepts a 3.5mm AUX cable, so you can run it wired when the battery is empty or when you want zero latency. The headline feature is hybrid active noise cancellation built around four microphones and a digital algorithm, which the brand says reduces ambient noise by up to 90% and targets low and mid-frequency sounds like car and airplane engines. That's the classic commute and flight profile.
Sound comes from custom 40mm dynamic drivers with a frequency range of 20Hz to 40kHz — Hi-Res-tuned, with extended highs for clarity and detail. Impedance is 16 ohms and sensitivity is 105dB, which makes it easy to drive from a phone. BassUp is the other signature trick: a double-press on the play button triggers real-time low-frequency analysis and boosts the bass, which is aimed squarely at EDM, hip-hop, and other bass-heavy genres. It's a colored, fun tuning rather than a flat reference one.
Battery is the standout. You get up to 40 hours of wireless playback with ANC on at 60% volume, expanding to 60 hours in standard music mode, and a 5-minute charge buys about 4 hours of listening. A full charge takes roughly 2 hours via USB-C. Bluetooth 5 is on board with a range of about 15 meters, and the controls are physical buttons rather than touch. The earcups are foam-padded ovals in a polycarbonate shell, and the whole headphone weighs 9.28 ounces. In the box you get the headphone, a USB-C cable, an AUX cable, and a travel pouch — everything you need for a trip. There's also a transparency mode for hearing your surroundings without taking the headphones off.
Buy it if you want one pair that handles commuting, flights, office work, and calls, and you value long battery life and switchable wired/wireless use. Skip it if you need maximum passive isolation with no battery dependency, prefer a neutral monitoring signature, or want the compact in-ear form factor.
• Best for pure noise isolation without battery → erjigo KZ ZS10. Its 26dB passive isolation works with zero power.
• Best for active noise cancellation → Anker Soundcore Life Q20. Four mics and hybrid ANC target engine and traffic drone directly.
• Best for battery life → Anker Soundcore Life Q20. Up to 60 hours in standard mode, or 40 with ANC on.
• Best for wired-only simplicity → erjigo KZ ZS10. No charging, no pairing, just a 3.5mm jack.
• Best for wireless freedom → Anker Soundcore Life Q20. Bluetooth 5 with about 15 meters of range.
• Best for critical listening and monitoring → erjigo KZ ZS10. Five drivers per side and a 7Hz–40kHz range favor detail retrieval.
• Best for bass-heavy casual listening → Anker Soundcore Life Q20. BassUp is built for exactly that.
• Best for travel and long trips → Anker Soundcore Life Q20. The travel pouch, AUX cable, and 60-hour ceiling make it the trip-friendly pick.
In my opinion, the right choice comes down to one question: wired focus or wireless convenience? If you want a compact, wired, genuinely isolating IEM for listening, monitoring, or gaming, I'd buy the erjigo KZ ZS10 — the five-driver array, metal-resin build, and 26dB passive isolation are a lot of engineering in a tiny package. If you want one headphone to handle commutes, flights, and the office with active cancellation and marathon battery life, I'd buy the Anker Soundcore Life Q20 instead. They solve different problems, so pick the problem you actually have.
what is the best wired noise cancelling headphones
Strictly speaking, the KZ ZS10 is wired noise isolating, not active noise cancelling — it blocks up to 26dB passively through its sealed in-ear fit. The Life Q20 does offer genuine active noise cancellation, and it can run wired via its included AUX cable, but its ANC is powered by its battery. If you specifically want ANC while wired, the Life Q20 is the one that fits that description.
is there wired noise cancelling headphones
Yes — the Anker Soundcore Life Q20 is a wireless headphone that also works wired through its 3.5mm AUX cable, and it carries its hybrid ANC. The one caveat is that active cancellation depends on battery power, so the wired experience isn't fully passive. The KZ ZS10 is wired-only with passive isolation instead.
what are the best wired noise cancelling headphones
It depends on what you mean by "wired." For pure wired isolation with no battery at all, the KZ ZS10's 26dB passive seal is the more dependable option. For wired listening with active cancellation, the Life Q20 pairs its ANC with an AUX cable. Neither is objectively "best" — they're built for different jobs.
They use very different materials. The KZ ZS10 combines a 304 stainless steel faceplate with a resin cavity and a detachable 0.75mm 2-Pin cable designed to resist pin breakage, backed by a 1-year manufacturer warranty. The Life Q20 uses a polycarbonate shell with foam earcups and carries an 18-month warranty. Which lasts longer depends on how you treat them.
