Anker Soundcore Liberty 4 NC

The spec sheet reads like a $200 product: LDAC hi-res, multipoint that keeps working even with LDAC enabled, 8 hours of ANC-on battery (12 with it off), IP55, and a 10-minute charge that buys five hours. Street price routinely sits at $80-100 (currently $79 on Amazon), which is why owners keep calling these the default recommendation under $100. The 9.2mm wool-paper drivers deliver big, tunable bass, and the HearID hearing-test EQ in the app genuinely changes the sound rather than nudging it. ANC 3.0 re-adjusts every 0.3 seconds and is tuned hard at voices — good in an office, though reviewers agree it lands mid-pack overall, below Bose and Sony's flagships. The compromises owners actually report: the squeeze-stem controls are fiddly and easy to mis-trigger, the glossy design reads a bit cheap, and the Dolby Audio toggle is more of an EQ effect than real spatial audio. Call quality with six mics is a genuine strength for the price. If you want 90% of the flagship experience for a third of the money and can live with average ANC, this is the value pick of the class.

Best for budget buyers who want flagship features under $100

The Space A40 remains the budget ANC benchmark two-plus years after launch, and recurring $45 sales keep it planted on best-seller lists. The adaptive noise cancelling legitimately hangs with buds twice the price, the buds are small enough to sleep on, and you get LDAC, true multipoint, and a wireless-charging case — a spec sheet nothing else at this price matches. Caveats from long-term owners: LDAC drops battery from 8 hours (ANC on) to roughly 5, the touch controls don't cover volume by default and there's no wear detection, and the mics are mediocre for outdoor calls. Some report one bud developing faster battery drain past the one-year mark, which drags the Amazon average to 4.2. If you want maximum ANC per dollar and can live with average call quality, this is still the pick.

The A20i is Anker's answer to the sub-$30 crowd, and reviewers keep reaching for the same comparison: they sound like earbuds twice the price. The default tuning is warm and punchy, and the Soundcore app's 22 EQ presets plus a custom equalizer let you dial in audiobooks or bass-heavy playlists — genuinely useful software that most budget buds skip entirely. Battery is a standout 9 hours per charge and 28 total, with a 10-minute quick charge buying 2 more hours. Owners also single out the comfort: Anker uses shorter, softer ear tips than usual, so these disappear in your ears over long sessions, and the 2-mic call quality earns consistent praise. The honest caveats: no ANC, no transparency mode, no multipoint, and no wireless charging — and Anker only rates them vaguely 'water-resistant' rather than publishing an IP number, so treat sweat resistance conservatively. Early units had laggy touch controls, though a firmware update largely fixed the delay. If you have $30 and just want good sound, comfort, and battery without noise cancelling, this is one of the easiest picks in the budget tier.

The P30i is the current default answer to 'cheapest ANC earbuds that actually cancel noise.' The adaptive system claims up to 42dB of reduction and picks its own strength, and owners back it up on the stuff that matters: engine hum, AC drone, and subway rumble drop to a distant murmur — several say it beats their older AirPods or Beats at this one job. Voices and mid-range chatter still leak through, which is the honest gap between this and $80+ ANC, but at 50-60% volume most of an office or bus disappears. Sound is classic Soundcore: bass-forward via 10mm drivers and BassUp, tameable with 22 presets or a custom EQ in the app. You also get things budget buds usually skip — Bluetooth 5.4, multipoint, transparency mode, IP54 dust and water resistance, and a case that flips into a phone stand, a gimmick owners end up genuinely using on flights. Battery is 10 hours per charge (figure roughly 6-7 with ANC on) and 45 total, with a 10-minute charge adding 2 hours. Caveats: no wireless charging, no published codec support beyond the basics, and the ANC can't touch crying babies or conversations. For $30 street, that's a very short complaint list.

Best for Commuters who want real ANC under $30

The P20i is what happens when Anker optimizes purely for the Amazon search results page: $20, 10-hour buds, big 10mm drivers, and over 90,000 ratings. For casual listening it genuinely delivers — bass-heavy out of the box, but the Soundcore app's 22 EQ presets tame it, and IPX5 handles sweat fine. Know what you're skipping: no ANC, no transparency mode, no multipoint, no wireless charging, and the pebble-shaped buds are bulky enough that smaller ears struggle to get a stable seal. Call quality is passable indoors and falls apart outside in wind despite the 'AI clear calls' marketing. Long-term owners mostly report the batteries holding up, though a vocal minority see one bud draining faster after a year. As a first pair or a beater set, nothing at this price is more proven.

Best for first-time earbud buyers on a tight budget

The Space One reads like a spec-sheet ambush: adaptive ANC, LDAC, multipoint, wear detection, and 40 hours with ANC on, usually for around $80. The noise cancelling is genuinely strong for the class — Soundcore's voice-reduction push means it handles chatter better than the JBL Tune 770NC — though you can hear a faint hiss in quiet rooms. Out of the box the tuning is deeply bass-heavy, and the Soundcore app's excellent custom EQ is basically mandatory. Build is all plastic with a slightly toylike headband slider, and clamp force is firm until it breaks in; pads are roomy but shallow. LDAC works, but you trade battery life and a bit of connection stability for it. Call quality is mediocre in noise despite the AI mic marketing. For under $100 it's one of the most complete feature sets in headphones, flaws included.
