How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want serious active noise cancellation, app-tuned sound and a gaming mode in one pair, choose Spigen True; if you need a light, airy semi in-ear fit with the newest Bluetooth on the block and a friendlier way in, choose Defunc True LITE II. That is the whole decision in one line. Everything below is just me showing you the work.
• Spigen True's biggest strength: up to 40dB of active noise cancellation plus a 30-hour total battery figure — a combo built for blocking out a commute or a noisy office.
• Spigen True's biggest trade-off: it is a fully sealed in-ear with a plastic/silicone build and a single white colourway, so it is functional rather than stylish, and the seal is the point.
• Defunc True LITE II's biggest strength: a semi in-ear, Scandinavian-minimal design with Bluetooth 6.0, IPX4 water resistance and a 13mm dynamic driver in a genuinely compact shell.
• Defunc True LITE II's biggest trade-off: passive noise cancellation only, and a total playtime figure of 20 hours rather than 30 — it isolates less and runs shorter between case top-ups.
• Who Spigen True is for: the buyer who wants maximum quiet and the longest runtime, and does not mind a deeper in-ear fit.
• Who Defunc True LITE II is for: the buyer who wants all-day comfort, a lighter look and the latest Bluetooth, and treats noise isolation as a nice-to-have.
Spigen True is the "get out of my way, I'm listening" earbud. The headline spec is up to 40dB of active noise cancellation — that is real, hardware-driven suppression, not just a tighter seal. Paired with 7.5 hours on a single charge stretching to 30 hours with the case, it is designed for people who put the buds in at the start of a flight or a workday and forget about the charger. The frequency range runs a standard 20Hz to 20,000Hz, so nothing exotic on paper — the story here is the ANC and the runtime, not audiophile tuning.
The feature list is unusually broad for the price bracket this kind of bud tends to sit in. There is a dedicated gaming mode with low-latency transmission, which matters if you are the type who games on a phone or handheld and hates lip-sync drift. There is a customising app with five preset sound profiles and a full equalizer, so you are not stuck with the factory curve. And there are six microphones, which is a lot of mics — that is a call-clarity play, not a music one. Bluetooth 5.2 handles the connection, which is current enough to be stable and power-efficient.
One more thing worth flagging honestly: the spec sheet lists the battery charge time as 30 hours, which is a weird way to describe charging. Read that as "the total system life is 30 hours with the case," and treat the real single-charge number as the 7.5 hours. That is the figure I would plan around.
Defunc True LITE II: Who It's For
Defunc True LITE II is the opposite philosophy. It is a semi in-ear bud — meaning it rests at the opening of your ear canal rather than plugging it — and that single design choice explains almost everything else about it. You get a lighter, more natural feel, more awareness of your surroundings, and none of the pressure a sealed tip creates over a long day. The trade-off is baked in: the noise control is passive only. There is no ANC chip here. The isolation you get is whatever the shape of the bud and your ear gives you, and nothing more.
What you do get is genuinely current hardware for an everyday bud. Bluetooth 6.0 is the newest version in this comparison, with a stated 10-metre range. The driver is a 13mm dynamic bass driver at 16 ohms impedance — 16 ohms is low, which means it is easy to drive and will sound full even off a phone at modest volume. The spec sheet calls it a bass driver specifically, so expect a warm, bass-forward tuning rather than a flat studio sound. There is ENC (environmental noise cancellation) for calls, which cleans up your voice on the mic side even though it does nothing for what you hear. Low latency is handled too, plus IPX4 water resistance for sweat and light rain.
Comfort is clearly the pitch. It is semi in-ear, ergonomic, and light — the case itself is small at roughly 5 by 2.5 by 5 centimetres, so it disappears in a pocket. Total playtime is up to 20 hours, which is a full working week of commutes for a lot of people but genuinely less than the Spigen. Controls are touch-based, and there is AI app support for a "smarter" listening experience. The brand leans hard on its Swedish design identity — minimal, functional, colour-forward. If you care about how the thing looks on your desk, that is a real point in its favour.
Who should buy it? People who wear buds for hours and hate the sealed-ear feeling. Runners, cyclists and city walkers who want to hear traffic. Anyone who values a clean, minimal look and the latest Bluetooth version. Who should skip it? If your main use case is a loud train or a noisy café and you want the world to go quiet, this is the wrong tool. Passive isolation on a semi in-ear bud will not get you there, and 20 hours of total playtime is the shorter of the two figures here.
• Best for noise cancellation → Spigen True. Up to 40dB of active cancellation versus passive-only on the Defunc. This is not close, and it is the single biggest difference between them.
• Best for battery life → Spigen True. 30 hours total with the case against 20 hours on the Defunc.
• Best for comfort over long sessions → Defunc True LITE II. The semi in-ear fit avoids the plugged-ear pressure of a sealed bud.
• Best for staying aware of your surroundings → Defunc True LITE II. Semi in-ear means traffic, announcements and conversations still reach you.
• Best for gaming and low-latency video → Spigen True. A dedicated gaming mode is called out on the spec sheet; the Defunc offers low latency but no gaming-specific mode.
• Best for the latest connectivity → Defunc True LITE II. Bluetooth 6.0 beats Bluetooth 5.2 on version, with a stated 10-metre range.
• Best for sound tuning flexibility → Spigen True. Five presets plus a custom equalizer in the app. The Defunc leans on its 13mm bass driver and AI app support instead.
• Best for workouts and wet weather → Defunc True LITE II. IPX4 water resistance is listed; the Spigen sheet does not list an IP rating.
• Best for a minimal, design-led look → Defunc True LITE II. Scandinavian styling and colour options versus Spigen's plain white utility build.
In my opinion, Spigen True is the better buy for most people, and it is the one I would pick. The reason is simple: active noise cancellation at up to 40dB and 30 hours of total playtime are the two things that actually change how you use earbuds day to day, and the Defunc cannot match either. The gaming mode and the equalizer app are genuine bonuses on top. I would only steer you to Defunc True LITE II if comfort and awareness matter more to you than silence — for running, cycling or wearing buds for eight straight hours, the semi in-ear fit and lighter build are the smarter call, and Bluetooth 6.0 is a nice piece of future-proofing. Two good buds, two different jobs. Buy for the job you actually have. Check the current price on Amazon for both before you commit.
Yes, clearly. Spigen True lists up to 40dB of active noise cancellation. Defunc True LITE II relies on passive noise cancellation only, meaning it depends on the physical fit rather than electronics. If blocking noise is your priority, Spigen wins.
Spigen True gives 7.5 hours on a single charge and up to 30 hours with the charging case. Defunc True LITE II lists up to 20 hours of total playtime. Spigen offers roughly ten more hours of system runtime.
Defunc True LITE II, in my opinion, because it uses a semi in-ear design that sits at the ear opening instead of sealing the canal. Spigen True is a fully in-ear bud, which isolates better but can feel more intrusive over long stretches.
They list IPX4 water resistance, which covers sweat and light splashes, and the semi in-ear fit keeps you aware of your surroundings. That combination makes them a reasonable pick for exercise. Spigen True does not list an IP rating.
I do not publish prices here, since they change constantly. Both are positioned as everyday earbuds rather than flagship models, so check the current price on Amazon for each before deciding.
