Best Earbuds for Call Quality: Why Two-Way Clarity Matters More Than ANC Alone

You can have strong ANC and still hear, "I can barely hear you" from the other end of the call. That usually happens when the earbuds make the world quieter for you, but the microphones still send your background noise to everyone else. The best earbuds for call quality need to solve both sides of that problem: inbound clarity, so you hear the caller, and outbound clarity, so the caller hears you.

This is what two-way call clarity means. In this guide, we will break down why ANC alone is not enough, how AI call noise reduction improves the microphone side of a call, and how Liberty 5 Pro combines Adaptive ANC 4.0 with Whisper-Clear Calls for clearer conversations in everyday noise.

Why Calls Can Still Sound Bad with Strong ANC

Strong ANC can make a subway platform or open office feel quieter in your ears, but it does not automatically clean up what your microphone sends to the caller. The earbuds may be working on the listening side while keyboard clicks, traffic, or nearby voices still reach the other end.

That is why the same call can feel clear to you and messy to them. The better question is not only how strong the ANC is, but whether the earbuds also improve outbound voice pickup. That is what two-way call clarity is meant to answer.

What Is Two-Way Call Clarity?

Two-way call clarity is the ability of earbuds to improve both sides of a phone call: what you hear and what your caller hears. It is different from inbound noise cancellation alone because ANC mostly improves your listening environment, while outbound voice processing improves the microphone signal sent to the other person.

Think of a call in a busy coffee shop. ANC can lower the room noise in your ears, so you can focus on the voice coming through. But if the earbud microphones also pick up the espresso machine, music, and nearby conversations, your caller still has to work hard to understand you.

That is where outbound call clarity becomes important. The earbuds need to identify your voice, separate it from surrounding noise, and send a cleaner voice signal. A useful rule: if the problem is "I cannot hear them," look at ANC. If the problem is "they cannot hear me," look at microphone pickup and AI call noise reduction.

That distinction is central to how we design call clarity on Liberty 5 Pro. Adaptive ANC 4.0 supports inbound listening, while Whisper-Clear Calls supports outbound voice pickup, so the call does not depend on ANC alone.

How AI Call Noise Reduction Helps the Person on the Other End

AI call noise reduction helps the person on the other end by processing the microphone signal before it reaches them. Instead of treating every sound around you equally, the system looks for the parts most likely to be your voice and reduces the parts more likely to be background noise.

In real use, the challenge is not just volume. Human speech overlaps with many everyday sounds. A bus engine can cover lower frequencies. Wind can create bursts across the microphones. Nearby voices can be harder to separate than a steady fan because they also sound like speech. That is why modern call systems use multiple inputs, not just one microphone.

The benefit is practical. If you take a call while walking near traffic or standing in a crowded lobby, a stronger microphone system has more information to work with than a basic single-mic design. The goal is not to make the world silent. The goal is to make your voice easier for the caller to follow.

For readers who want a deeper technical background, our guide to AI call noise cancellation explains how microphone-side processing differs from standard ANC.

Whisper-Clear Calls on Liberty 5 Pro Improve Outbound Clarity with Thus AI

Whisper-Clear Calls is the outbound call system on Liberty 5 Pro. It is designed for the part of the call your caller experiences: whether your voice comes through clearly when your environment is loud.

The system combines 8 MEMS microphones with 2 bone-conduction VPUs (voice pickup units). The MEMS microphones capture the sound field around you, while the VPUs add a second type of voice signal by detecting vibration from your speech. That matters because the VPU signal is less exposed to some surrounding airborne noise than a microphone alone.

Then the ANKER Thus AI chip helps process the combined input directly on the earbuds. In plain language, the earbuds are not only listening for sound; they are using multiple signals to decide what should be treated as your voice.

This is also why it is important not to describe Liberty 5 Pro as bone-conduction earbuds. Liberty 5 Pro is an in-ear ANC earbud. The bone-conduction VPUs are sensors used for voice pickup during calls, not an open-ear bone-conduction listening design.

For users who spend a large part of the day in calls, the difference shows up in ordinary moments: joining a meeting from a shared office, stepping outside during a phone call, or answering a client while boarding transit. Liberty 5 Pro also holds the Guinness World Records title for the highest speech quality score (G-MOS) among true wireless earbuds, giving this call-first design a measurable proof point. The caller may still hear some context in extreme noise, but your voice is better protected from being buried by it.

Adaptive ANC 4.0 Helps You Hear the Caller

Adaptive ANC 4.0 handles the inbound side of calling on Liberty 5 Pro. During a call, it reduces surrounding noise in your ears so you can follow the caller more easily in train stations, open offices, and busy streets.

That matters on long calls because listening effort adds up quickly. When less room noise reaches your ears, you spend less mental energy separating the caller's voice from your environment. For call-focused use, inbound clarity works best alongside outbound voice pickup, not instead of it.

If calls are your priority, look for both Adaptive ANC and a dedicated microphone system in the same earbud. For broader everyday focus and commuting, browse our ANC earbuds collection.

Does Two-Way Call Clarity Work in 100 dB+ Noisy Environments?

Yes, two-way call clarity can significantly improve calls in 100 dB+ noisy environments, but no earbud should be expected to erase every background sound. At that level—motorcycles, construction tools, crowded transit platforms, or loud event spaces—the call system has to work much harder, and the caller may still hear traces of the environment.

On Liberty 5 Pro, Adaptive ANC 4.0 helps you hear the caller through the noise, while Whisper-Clear Calls helps keep your voice present for the person on the other end. That two-direction approach can deliver clearer voice pickup than a basic microphone system in the same setting, even when the surroundings are extreme.

Clear-call technology is not hearing protection. According to NIOSH noise exposure guidance, loud sound can create hearing risk depending on level and duration. ANC and call noise reduction can improve communication, but they should not be treated as a substitute for proper hearing protection in hazardous noise.

For the best results in very loud places, combine the technology with a few simple habits:

• Keep both earbuds in so ANC and voice pickup work as intended.
• Move away from direct wind or the loudest noise source when you can.
• Speak at a steady volume instead of shouting, which can distort speech.

Conclusion

If your calls happen only in quiet rooms, almost any decent earbud can sound acceptable. The difference appears when life gets louder: the airport gate, the shared office, the sidewalk, or the coffee shop between meetings. That is where two-way call clarity becomes more useful than judging earbuds by ANC alone. Liberty 5 Pro brings inbound noise control and outbound voice pickup into one call-first design, so conversations stay easier on both sides.

FAQs

What is two-way clear call technology in premium ANC earbuds?

Two-way clear call technology improves both directions of a call. The inbound side helps you hear the caller, usually through ANC and earbud audio processing. The outbound side helps the caller hear you, usually through microphones, voice pickup sensors, and AI call noise reduction. Premium ANC alone may make the call clearer in your ears, but it does not automatically clean up your microphone signal.

How does AI call noise reduction help the person on the other end hear you clearly?

AI call noise reduction works on the microphone side of the call. It analyzes incoming signals, identifies the parts most likely to be your speech, and reduces background noise before the signal reaches the caller. This is why it matters most when you are the one speaking from a noisy place.

What is Whisper-Clear Calls on soundcore Liberty 5 Pro?

Whisper-Clear Calls is the outbound call clarity system on soundcore Liberty 5 Pro. It combines multiple microphones, bone-conduction voice pickup, and ANKER Thus™ AI processing to help isolate your voice from background noise. It is designed to help the person on the other end hear you more clearly when you are calling from busy or noisy places.

How does Adaptive ANC 4.0 help during phone calls?

Adaptive ANC 4.0 helps with the inbound side of phone calls. It reduces the noise around you so the caller's voice is easier to hear through your earbuds. This is different from Whisper-Clear Calls, which focuses on the outbound side of the call. In simple terms, ANC helps you hear them, while Whisper-Clear Calls helps them hear you.

Does Whisper-Clear Calls work in 100 dB+ noisy environments?

Yes, Whisper-Clear Calls can significantly improve voice pickup in 100 dB+ noisy environments, but it should not be described as removing all background noise. Extremely loud places still create difficult conditions for any earbud microphone system. The practical benefit is that your voice can stay easier to understand, while some environmental sound may still remain.
