Note: Both support LDAC for hi-res audio—rare at this tier!
Great noise-cancelling earbuds shouldn’t require a financing plan. We tested two Soundcore stars: the **A40** (a lightweight overachiever) and the **Liberty 4 NC** (a feature-packed contender). Both deliver **adaptive ANC, 10+ hour battery life, and IPX4 sweat resistance**, but which balances **performance and value** better?
The A40 packs **custom 11mm drivers, 6-mic AI noise reduction, and a compact case** that disappears in pockets. The Liberty 4 NC counters with **hybrid ANC, spatial audio, and a sleek stem design**. We tested both through **commutes, gym sessions, and marathon Zoom calls** to compare **noise cancellation depth, comfort, and sound quality**.
Whether you prioritize **stealthy comfort** or **premium features**, here’s the unfiltered mic test.

1. A40: Featherweight ANC Champion
The **Soundcore A40** is **the ninja of budget earbuds**—tiny, potent, and shockingly capable. The **11mm titanium drivers** deliver crisp highs and mids (perfect for podcasts), while the **adaptive ANC** adjusts seamlessly between subway rumbles and office chatter. At just **4.3g per bud**, they vanish in your ears during workouts. The **IPX4 rating** shrugged off sweat during spin class, and the **50-hour total battery** (10hr buds + 4 case charges) outlasts most weekend trips.
After 3 weeks of testing: **Zero connectivity drops**, minimal ear fatigue, and the **wireless charging case** (a budget rarity) worked flawlessly. The **Soundcore app** lets you tweak EQ or enable ‘Transparency Mode’—though ANC maxes out at **35dB** (quieter than Liberty 4 NC). Perfect for **all-day wearers and minimalists** who want **‘set-and-forget’ reliability**.
Pro tip: Use the ‘Soundcore Signature’ EQ preset for balanced acoustics.
2. Liberty 4 NC: Feature-Packed Performer
The **Soundcore Liberty 4 NC** is **a Swiss Army knife for audiophiles**—it crams premium tech into a budget-friendly shell. The **dual-driver system** (dynamic + balanced armature) separates instruments with startling clarity, while **LDAC support** streams higher-quality Apple Music/Spotify tracks. The **hybrid ANC** adapts to environments (blocked 85% of airplane cabin noise in tests), and the **spatial audio** adds faux ‘3D’ depth for movies.
Where it shines: **10-hour playtime with ANC on**, a **slimmer stem design** for better mic pickup, and **HearID 2.0** that tailors EQ to your hearing. The **pressure-relief vents** eliminate that ‘clogged ear’ feeling during long flights. Downsides: **Case lacks wireless charging**, and the glossy finish attracts fingerprints. Ideal for **commuters and music nerds** who crave **detail without compromise**.
Warning: Disable LDAC if your phone stutters—it’s bandwidth-heavy.
