$57 Anker Earbuds Just Exposed Why You're Overspending on Audio

Here's a truth nobody wants to hear: flagship earbuds at ₹20,000+ are built on marketing, not physics. The Anker Soundcore Liberty 4 NC just dropped to $57 (roughly ₹4,800), and it's doing something genuinely uncomfortable to the premium audio industry—it's proving that at some price point, you've already got everything that matters.​

The earbuds reduce noise by up to 98.5%, last 10 hours per charge with active noise cancellation enabled, support hi-res audio via LDAC codec, and come with a case that supplies 50 additional hours of playback. For $57. With Amazon matching the price across regions.​

The uncomfortable part? Most reviewers don't have meaningful criticisms. They're just... good. Genuinely good.

What You Actually Get for $57

Let's be specific about what Anker packed into these earbuds because the specs are actually wild for the price.

The Liberty 4 NC uses an 11mm custom-tuned driver—the same oversized driver size found in earbuds triple the price. That driver sits alongside an innovative noise isolation chamber and a high-sensitivity in-ear sound sensor that detects a wider range of sounds without distortion.​

The active noise cancellation system performs at a level that makes ₹15,000+ earbuds look expensive, not superior. Independent testing by SoundGuys confirmed 9 hours 53 minutes of continuous playback with ANC on. That's not theoretical battery life. That's real-world measurement. The case adds approximately 50 more hours, meaning you can go days without touching a power cable.​

The sound tuning is deliberately bass-forward—11mm drivers with custom drivers tend to be—but the implementation doesn't sacrifice detail or destroy the midrange like cheaper earbuds do. PCMag called the sound profile "robust bass depth with bright highs" and noted the tuning has "noticeable sculpting" but works well. In plain English: if you like bass (and most listeners do), these deliver. If you want a flat reference sound, they'll feel warm and energetic rather than neutral.​

LDAC codec support means Android users can stream hi-res audio if their phone supports it. For iPhone users, this is irrelevant—Apple uses its own audio standards—but it's there if you need it.​

Water resistance is IPX4, which handles rain and sweat but isn't designed for underwater use or shower submersion. Fair trade-off at this price.​

The app is where Anker really flexes. You get 22 EQ presets, the ability to create custom profiles, ANC mode switching (Adaptive, Manual, or Off), and even transparency mode customization. Most $200+ earbuds don't have this level of control.​

Why This Price Exists (And Why It's Temporary)

The Liberty 4 NC normally retails for ₹7,500–₹8,000 ($99–$100 USD) when not on sale. The $57 deal is a limited-time aggressive discount—likely a Black Friday push or inventory clearance before a newer model.​

Here's the uncomfortable truth about the audio industry: there's a price ceiling where adding more money stops adding meaningful value. For earbuds, that ceiling seems to be somewhere between $60–$100. Below that, you're making real trade-offs. Above that, you're often paying for brand prestige, design aesthetics, or niche features (like perfect integration with Apple's ecosystem).

At $57, the Liberty 4 NC is essentially being sold at a price where Anker can barely make profit margins in some regions. Why would they do this? Multiple reasons: flush out old inventory before the Liberty 5 goes mainstream, capture market share in price-sensitive categories, or bank on you buying their ecosystem (charging cables, replacement ear tips, their ecosystem of products).

It works because at $57, even mediocre earbuds would be impressive value. These aren't mediocre.

Where This Fits for Indian Buyers

For Indian readers, the relevance here is context, not direct comparison. The Anker Soundcore Liberty 4 NC typically costs ₹6,500–₹7,500 on Amazon India when not on sale. During sales, it drops to ₹5,000–₹6,000.​

That puts it squarely in competition with Realme Buds Air 7 Pro (₹3,499), OnePlus Buds 4 (₹4,999), and CMF Buds 2 Plus (₹3,299) according to current listings.​

Here's where the Liberty 4 NC pulls ahead: noise cancellation performance. Independent testing confirms the Realme and OnePlus models have excellent ANC for their price—49–50dB cancellation—but the Liberty 4 NC's Adaptive ANC 2.0 system with real-time environment detection still outperforms them. It's not a massive gap, but it's measurable.​

Battery life comparison is tighter. Realme Buds Air 7 give 8–9 hours with ANC on versus Liberty 4 NC's 10 hours. OnePlus Buds 4 also deliver 8 hours with ANC. The difference is meaningful only on long travel days.​

Sound quality? This is subjective, but most reviews place the Liberty 4 NC's bass-forward profile above the more balanced Realme and OnePlus tunings if you prefer energy and punch. If you want reference-level accuracy, the Indian options might feel more neutral.​

So here's the real question: do you pay ₹3,500–₹4,000 more for measurably better ANC and battery life, or do you save money with alternatives that handle 90% of use cases equally well?

For most people commuting on Delhi Metro or Bangalore traffic, the cheaper options are honestly enough.

The Uncomfortable Takeaway

The Soundcore Liberty 4 NC at $57 is doing something that threatens the entire premium audio market: it's proving that diminishing returns kick in early. You can spend $57 and get earbuds with ANC that works, battery that lasts, hi-res audio support, and a capable app. Spending $200+ adds wireless charging, maybe a shinier case, and primarily the privilege of telling people you spent more money.

This isn't unique to Anker. The EarFun Air Pro 4 at $89 is comparably good. The CMF Buds 2 Plus at ₹3,299 in India are genuinely solid. The Samsung Galaxy Buds Core at ₹4,999 check most boxes.​

The real market winner isn't audio quality anymore—it's which specific implementation of good-enough matches your preferences. Do you want bass? Soundcore. Want neutrality? CMF. Want ecosystem integration? Nothing Ear. Want affordability? Realme.

For $57, the Liberty 4 NC is absurd value. But take that same $57 and look at what alternatives exist at local pricing in India, and suddenly the story gets more complex. You might find something equally good or good-enough that lets you spend that savings elsewhere.

The uncomfortable truth the audio industry doesn't want you realizing: flagship pricing isn't about audio quality anymore. It's about convincing you that paying more is different from buying more.

At $57, Anker's just making that subtlety obvious.
