How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want the more advanced noise-cancelling system with adaptive processing and hi-res audio support, choose Anker soundcore; if you need sport-ready earbuds that stay put during hard workouts and keep going for days between charges, choose occiam Active Noise Cancelling.
• Anker soundcore — biggest strength: Adaptive ANC 2.0 that recalculates in real time to your ears and surroundings, plus up to 98.5% noise reduction and LDAC hi-res audio.
• Anker soundcore — biggest trade-off: IPX4 only, so it handles a downpour or a spill but is not built for heavy sweat sessions or swimming.
• occiam Active Noise Cancelling — biggest strength: Flexible ear hooks that lock in place, a 96-hour total playback figure with the case, and a digital LED display so you can see exactly how much charge is left.
• occiam Active Noise Cancelling — biggest trade-off: Its ANC is described in general terms — it "significantly reduces ambient noise" — rather than a specific reduction figure, so expect solid quieting rather than class-leading silence.
• Who each pick is for: Anker soundcore for commuters, travellers and listeners who care most about quiet and sound detail; occiam for runners, gym-goers and anyone who wants earbuds that never fall out.
The Liberty 4 NC is built around one idea: making the world around you quieter, and doing it intelligently. Its Adaptive ANC 2.0 takes real-time measurements and adjusts to your ear canals and to the noise around you, and Anker states it cancels up to 98.5% of noise. If your daily battle is a bus engine, a plane cabin, a noisy open office or a loud train platform, that is exactly the scenario this design targets. The in-ear shape, the high-sensitivity in-ear sensor and the noise isolation chamber all work together toward that single goal.
Sound is the second pillar. The 11mm custom-tuned drivers are paired with LDAC support, which Anker says transfers roughly three times more data than regular Bluetooth for hi-res wireless audio. Then there is HearID 2.0, which maps a sound profile to your hearing, plus a fully adjustable EQ and 22 presets if you would rather just pick a flavour and go. That is a lot of tuning flexibility for someone who likes to fiddle.
Battery is strong in both modes: 10 hours per charge in normal mode and up to 50 hours with the case, dropping to 8 hours and 40 hours respectively with ANC on. You also get Bluetooth 5.3 with multi-point, quick pairing on Android, auto play/pause when you put them in or take them out, six beamforming mics with an AI algorithm for calls, IPX4 water resistance, wireless charging and touch controls.
occiam Active Noise Cancelling: Who It's For
The occiam T9 takes the opposite approach. Instead of chasing the deepest possible silence, it chases staying power and staying put. The headline number is 96 hours of total playback: about 8 hours on a single charge, with the case recharging the buds five to six times, or roughly 48 hours if you use one earbud at a time. The LED display on the case shows the remaining power of the case and the charging status of each earbud, which is genuinely useful when you are heading out for a long run or a weekend trip and cannot afford a surprise shutdown.
The fit is the other half of the story. Flexible ear hooks hold the buds in place through runs, jumps and yoga, and the soft silicone tips are designed for pressure-free wear over long sessions. The enclosure is ABS and the buds are described as sweatproof and rain-resistant, so workout sweat and stray raindrops are within their comfort zone. A 13mm dynamic driver pushes bass, midrange and treble, and the ANC is there to cut ambient noise interference for commutes, open offices and gyms.
Controls are physical buttons rather than touch, so you can play, pause, skip, change volume and take calls without looking or worrying about a mistimed tap with sweaty fingers. There is also a one-click reset: drop the buds in the case, hold the reset button inside for five seconds, and prior pairings are cleared. Bluetooth 5.3 covers the basics, and the package includes the case, ear tips, a Type-C cable and a manual.
Who should buy it: runners, gym regulars, cyclists and anyone whose earbuds keep falling out or dying mid-week. Who should skip it: listeners who want the most refined noise cancelling and the most detailed wireless audio codec support — that is not what this design prioritises.
Side-by-Side: Which Should You Choose?
• Best for sound quality and tuning → Anker soundcore. LDAC, 11mm drivers, HearID 2.0 and 22 EQ presets give you far more control.
• Best for workout security → occiam Active Noise Cancelling. Flexible ear hooks are the reason to pick it over a plain in-ear design.
• Best for total battery life → occiam Active Noise Cancelling. 96 hours with the case versus 50 hours on the soundcore.
• Best for battery transparency → occiam Active Noise Cancelling. The LED display shows real-time case power and per-bud charging.
• Best for calls in busy places → Anker soundcore. Six beamforming mics plus an AI algorithm are purpose-built for voice clarity.
• Best for control style → occiam Active Noise Cancelling if you prefer buttons; Anker soundcore if you prefer touch and auto play/pause.
• Best for sweat and rain → occiam Active Noise Cancelling for workout-level moisture; Anker soundcore for IPX4 splash protection on a commute.
In my opinion, most people torn between these two should buy the Anker soundcore. Adaptive ANC 2.0, the 98.5% noise reduction figure, LDAC hi-res audio, HearID 2.0 and six-mic call clarity make it the more capable everyday pair, and 50 hours with the case is plenty for a normal week. I would only steer you to the occiam Active Noise Cancelling if your priority is earbuds that physically will not budge during runs and jumps, and if that 96-hour figure matters more to you than the deepest possible quiet. For commuting and listening, soundcore wins; for sport, occiam wins.
