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 true wireless experience with active noise cancelling and a smart touchscreen case, choose CuiSuto Earbuds; if you need a lightweight, minimalist semi in-ear pair with newer Bluetooth and clear-call tech, choose Defunc True LITE II.
• CuiSuto Earbuds — biggest strength: Active Noise Cancellation with four adjustable modes, controlled straight from a smart touchscreen charging case. Biggest trade-off: A bulkier, more tech-heavy design that asks you to learn its touchscreen and touch controls.
• Defunc True LITE II — biggest strength: A featherweight semi in-ear fit with Bluetooth 6.0, ENC call clarity and low latency in a clean Scandinavian shell. Biggest trade-off: Passive noise cancellation only, and a shorter 20-hour total playtime.
• CuiSuto Earbuds is for you if you commute, work or train in noisy places and want to silence the world on demand.
• Defunc True LITE II is for you if you want simplicity, comfort and a pair that disappears in your ears for calls, podcasts and everyday listening.
• One line to remember: CuiSuto wins on noise control and playtime; Defunc wins on lightness and effortless comfort.
The CuiSuto Earbuds are built around control. The standout piece is the smart multifunctional touchscreen charging case. Instead of reaching for your phone, you tap the case itself to change volume, skip tracks, handle calls and even locate a missing earbud. That is a genuinely different way to live with true wireless earbuds, and for anyone who hates digging out a phone mid-commute, it changes the daily routine.
Sound and noise handling are the second pillar. A 13mm dynamic driver covers a 20Hz–20,000Hz range with rich lows and crisp highs, and five EQ modes let you shift the profile toward bass, vocals or something flatter. On top of that sits true Active Noise Cancellation with four adjustable modes you set through the case — useful on a train, in an open office or during a flight. The stem design with a metallic finish and an off-white color keeps them looking tidy, and the sweat- and dust-resistant build handles running, gym sessions and light workouts.
Who should buy them? People who want noise cancelling, long 60-hour playtime and phone-free control in one package. The earbuds weigh just 0.13oz each and are ergonomically shaped for extended wear, so work and study sessions are realistic. Who should skip them? If you prefer a barely-there semi in-ear fit, or you want the simplest possible pair with no menus to learn, the touchscreen case may feel like more device than you need.
The Defunc True LITE II takes the opposite approach: strip things back. Designed in Sweden, it leans on a semi in-ear ergonomic shape that sits naturally rather than sealing deep into the canal. That means all-day comfort with minimal pressure — the kind of earbud you forget you're wearing during a commute, a workday or a long podcast binge.
The spec sheet is modern where it counts. Bluetooth 6.0 is the newest wireless version here, pairing with a 10-meter range, and ENC (environmental noise cancellation) sharpens your voice on calls by cutting background sound at the microphone. Low latency matters if you watch video or play games, since audio stays closer to the picture. A 13mm bass driver handles the low end, and IPX4 water resistance shrugs off sweat and light rain. Total playtime is 20 hours, and there's AI app support for extra tuning.
Who should buy them? Anyone who values comfort, a clean minimal look and clear calls over heavy noise isolation. They suit students, commuters, remote workers and casual listeners who want one simple pair that just works. Who should skip them? If blocking out loud environments is your priority, remember the noise control here is passive — the semi in-ear seal helps, but it won't match active cancellation. And if you want the longest possible battery between charges, 20 hours is the ceiling.
Side-by-Side: Which Should You Choose?
• Best for noise cancellation → CuiSuto Earbuds. True ANC with four adjustable modes beats passive isolation.
• Best for all-day comfort → Defunc True LITE II. The semi in-ear design is lighter on the ear canal over long sessions.
• Best for phone-free control → CuiSuto Earbuds. The touchscreen case handles volume, tracks, calls and earbud location.
• Best for call clarity → Defunc True LITE II. ENC focuses on your voice, which matters on busy streets.
• Best for gaming and video → Defunc True LITE II. Low latency keeps audio and picture in sync.
• Best for workouts → Defunc True LITE II. IPX4 water resistance covers sweat and light rain; CuiSuto counters with a sweat- and dust-resistant build.
• Best for customization → both, differently. CuiSuto gives you 5 EQ modes; Defunc gives you AI app support.
In my opinion, I would buy the CuiSuto Earbuds if noise and battery are what keep you shopping. Active noise cancelling, 60 hours of playtime and a touchscreen case that removes your phone from the equation are three things the Defunc simply doesn't offer, and together they cover commuting, office work and training without compromise.
That said, I'd point a comfort-first buyer straight to the Defunc True LITE II. Bluetooth 6.0, ENC calls, low latency and a semi in-ear fit that stays light for hours make it the smarter everyday pick for people who rarely fight loud environments. Decide which of those two problems is really yours, and the choice makes itself.
how to connect true wireless earbuds
Open the charging case and take the earbuds out — they power on and enter pairing mode automatically. On your phone, open Bluetooth settings, find the earbud name and select it. Both the CuiSuto Earbuds and Defunc True LITE II pair wirelessly over Bluetooth, with no cable or jack involved.

Put the earbuds in the case first to make sure both are charged, then remove them so they link to each other. Enable Bluetooth on your device and pick the model from the available list. If nothing shows up, place them back in the case for a few seconds and repeat — the Defunc True LITE II supports Bluetooth 6.0 and the CuiSuto uses Bluetooth 5.4.

Tap the earbud surface to play, pause or take calls — both models use touch controls. On the CuiSuto Earbuds you can also use the touchscreen charging case to change volume, skip tracks and even locate a missing earbud. On the Defunc True LITE II, AI app support gives you extra control options.
how to bluetooth true wireless earbuds
Keep the earbuds within about 10 meters of your phone, which is the stated Bluetooth range of the Defunc True LITE II, and avoid thick walls between them. If audio stutters, move closer or re-pair from your device's Bluetooth menu. Charging the case regularly keeps both pairs ready to connect the moment you open the lid.
