How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wired, audiophile-grade hybrid driver in-ear monitor built for critical listening, choose Linsoul Kiwi Ears Quartet; if you need true wireless hybrid ANC earbuds with active noise cancelling and all-day battery, choose Cubitt Tracking Technologies Power Earbuds Pro.
• Linsoul Kiwi Ears Quartet — biggest strength: A four-driver hybrid setup (two dynamic + two balanced armature) in a hand-crafted medical-grade resin shell, with a detachable 2-pin OFC silver-plated cable. This is a wired IEM aimed squarely at detail and tonal balance.
• Linsoul Kiwi Ears Quartet — biggest trade-off: It's a wired 3.5 mm in-ear monitor. There's no active noise cancelling, no charging case, and no wireless freedom — you're tethered to a source.
• Cubitt Power Earbuds Pro — biggest strength: Active Noise Cancelling with dual-mic ENC, up to 30 hours of total playtime with the charging case, Bluetooth 6.0, and a 60 ms low-latency Game Mode. It's built for movement and calls.
• Cubitt Power Earbuds Pro — biggest trade-off: Sound quality is tuned for deep bass and everyday listening rather than studio-grade accuracy, and the drivers are a single dynamic type — not a multi-driver audiophile array.
• Who each pick is for: Pick the Quartet if you listen critically at a desk or studio and value wired fidelity. Pick the Power Earbuds Pro if you want wireless ANC for commuting, calls, and workouts.
The Quartet is a hybrid in-ear monitor, and the name is literal: four drivers working together. Two 10 mm titanium-diaphragm dynamic drivers are passively aligned in an isobaric subwoofer configuration, phase-synced to avoid wave cancellation. On top of that sit a custom mid-high balanced armature and a custom ultra-high tweeter balanced armature. In plain terms, that means the low end and the upper frequencies are handled by drivers purpose-built for each job.
Kiwi Ears crossed the dynamic drivers over with a passive low-pass network at 350 Hz, keeping the mids from 350 Hz to 1 kHz flat so vocals and instruments stay accurate rather than getting buried under bass. With a 20 Hz–20 kHz frequency range, 32 ohm impedance, and 110 dB sensitivity, it's an easy load for most phones, dongles, and portable players. The shell is hand-crafted medical-grade resin, polished, and skin-safe, and the 2-pin connector means you can swap cables later. It ships with an oxygen-free silver-plated copper cable.
So who should buy it? Anyone who listens at a desk, in a studio, or during long focused sessions and wants wired consistency — DJs, musicians, and gamers who don't want latency or battery anxiety. Who should skip it? If you want to move around untethered, take calls on the go, or block out a train carriage with active noise cancelling, this isn't the tool. It isolates sound passively; it doesn't cancel it electronically.
Cubitt Tracking Technologies Power Earbuds Pro: Who It's For
Battery is the headline. You get 6.5 hours per charge with ANC off, or 4.5 hours with ANC on, and the 500 mAh case extends total playtime up to 30 hours. The case carries roughly 3.7 full recharges, and a 90-day standby means they're still alive after weeks forgotten in a bag. USB-C charging keeps it simple. Bluetooth 6.0 (BT8932E chipset) handles pairing and a stable connection up to 10 meters, with AAC and SBC decoding.
Two features stand out for specific buyers. Game Mode drops latency to about 60 ms, which matters if you're gaming or watching video and hate lip-sync drift. And IPX5 splash and sweat resistance covers workouts and light rain. Multiple ear tip sizes are included for fit.
Who should buy it? Commuters, call-heavy workers, gym-goers, and casual gamers who want one pair that does everything wirelessly. Who should skip it? If your priority is maximum resolution and a wired, tunable, cable-swappable setup, the single-driver, bass-forward tuning here won't satisfy that itch.
• Best for pure sound quality and detail → Linsoul Kiwi Ears Quartet. Four drivers (2DD + 2BA) with a flat 350 Hz–1 kHz midrange is a fundamentally more resolving architecture than a single dynamic driver.
• Best for noise cancelling → Cubitt Power Earbuds Pro. It's the only one of the two with active noise cancelling; the Quartet relies on passive isolation only.
• Best for battery life and untethered use → Cubitt Power Earbuds Pro. Up to 30 hours total with the case versus no battery at all on the Quartet.
• Best for calls in noisy places → Cubitt Power Earbuds Pro. Dual-mic ENC is designed exactly for that; the Quartet has no mic array described.
• Best for gaming latency → Cubitt Power Earbuds Pro in Game Mode at roughly 60 ms. The Quartet's wired 3.5 mm connection has no wireless latency to worry about at all, which is its own advantage.
• Best for workouts and rain → Cubitt Power Earbuds Pro. IPX5 splash and sweat resistance; the Quartet is a wired resin IEM not built for sweat.
• Best for durability and longevity of the cable → Linsoul Kiwi Ears Quartet. The detachable 2-pin design means a worn cable can be replaced without replacing the earphones.
• Best for studio, DJ, and critical listening → Linsoul Kiwi Ears Quartet. That's the audience its tuning and driver layout are aimed at.
• Best for someone who wants one pair for everything → Cubitt Power Earbuds Pro, unless everything you do is at a desk.
My Verdict
what is hybrid anc earbuds
Hybrid ANC refers to active noise cancelling that uses more than one approach — typically feedforward and feedback microphones working together — to cancel more of the surrounding noise than a single-mic system. In the Power Earbuds Pro's case, the active noise cancelling is paired with dual-mic ENC, which reduces wind and background noise on your voice during calls. It's a wireless-earbud feature; the Quartet, being wired, uses passive isolation instead.
what is anc earbuds
ANC stands for Active Noise Cancelling: the earbuds use microphones and electronics to actively cancel incoming ambient sound, rather than just blocking it with a physical seal. The Cubitt Power Earbuds Pro lists 22 dB of active noise cancelling. That's useful on trains, planes, and in open offices. Passive isolation, like the Quartet's resin shell, only reduces noise by fit and material.
what are hybrid anc earbuds
They're wireless earbuds that combine active noise cancelling with an additional noise-handling system — here, dual-mic ENC for call clarity. The practical result is that you hear less of the world, and the person you're calling hears less of it too. If calls in noisy places matter to you, this is the feature to look for.
what are anc earbuds
Simply put, they're earbuds with built-in active noise cancellation. If your main goal is blocking out a commute or a busy room, choose the Cubitt Power Earbuds Pro. If your main goal is accurate, detailed sound in a quiet setting, the wired Linsoul Kiwi Ears Quartet is the better fit.
