How to Get the Best Call Quality from Wireless Earbuds

Why earbud call quality is inconsistent

The same earbuds that deliver excellent music can make you sound terrible on calls. This happens because audio playback and voice transmission involve different hardware paths — the speaker and ANC system drive your listening experience, while a separate microphone array and signal processor handle your voice.

Manufacturers optimise for what sells: audio quality and ANC performance appear in reviews and earn praise on YouTube. Microphone quality doesn't. Many earbuds above $100 have mediocre call microphones because the mic barely affects purchase decisions.

Understanding the microphone system and knowing how to configure it properly is how you get better call quality from the earbuds you already own — and how you pick better earbuds if you're buying with calls in mind.

How earbud microphone systems work

Most wireless earbuds use two to four microphones per earbud. These serve different purposes.

Primary voice mic: picks up your voice. Usually positioned on the earbud stem, the outer shell near your cheek, or at the base of an earbud without a stem. Position relative to your mouth matters — mics closer to the mouth pick up cleaner voice signal.

ANC mics: used for noise cancellation on the playback side. On some earbuds, these are shared with ENC processing; on others they're independent.

Wind noise microphones: some earbuds include dedicated mics angled to reduce wind turbulence before it reaches the primary voice mic.

Beamforming: higher-end earbuds use multiple mics to triangulate your voice direction and filter sounds coming from other angles. This is why professional-grade earbuds (Jabra Evolve2) sound so much cleaner on calls — the beamforming system focuses tightly on your voice.

ENC: the call quality spec nobody talks about

ENC (Environmental Noise Cancellation) is the microphone-side counterpart to ANC. Where ANC reduces what you hear, ENC reduces what callers hear from your environment.

Without ENC, callers hear everything your microphone picks up: your typing, a dog barking, traffic outside your window, the person at the next coffee shop table having a loud conversation. With strong ENC, they hear primarily your voice.

ENC quality varies dramatically. Budget earbuds run basic filtering that reduces obvious broadband noise. Premium implementations — Jabra, Apple AirPods Pro 2, Sony WF-1000XM5 — use AI-assisted processing that isolates voice frequencies specifically and suppresses background sounds that don't match the expected vocal frequency profile.

You can test ENC quality easily: have someone call you, put them on speaker on their end, and walk outside while on the call. A poor ENC mic makes every outdoor sound obvious. A good one keeps your voice clear even with significant background noise.

The Bluetooth codec for calls: why it's different

Here's something most guides don't mention: Bluetooth audio calls don't use the same codec as music playback. When you make a phone call through Bluetooth earbuds, the connection switches from the A2DP (Advanced Audio Distribution Profile) used for music to the HFP (Hands-Free Profile) used for calls.

HFP operates at much lower bitrates than A2DP — even SBC for music is substantially higher quality than HFP audio. This is why calls through wireless earbuds have a characteristic limited quality ceiling regardless of how premium the earbuds are for music.

HFP comes in two versions: standard (narrowband, 8 kHz sampling) and wideband/HD Voice (16 kHz sampling, sometimes called HFP 1.6 or higher). Wideband HFP makes voice sound noticeably more natural — less like a tinny phone call and more like talking in the same room. Whether you get wideband depends on both the earbuds and the carrier/phone supporting it.

Microsoft has introduced LC3 (the LE Audio codec) for calls, which significantly improves Bluetooth call audio quality on supporting devices. This is gradually rolling out in 2025–2026 earbuds.

Wind: the enemy of outdoor call quality

Wind is the most common cause of outdoor call quality failure. When wind blows directly over a microphone, it creates a low-frequency rumble (called wind noise) that overwhelms the voice signal.

Earbuds handle this in several ways. Physical windscreens (small foam or mesh covers over mic ports) reduce direct airflow over the diaphragm. Beamforming mics can partially null wind direction when it differs from your voice direction. Some companion apps include explicit "wind noise reduction" settings in call processing.

For calls in wind:

• Orient yourself so the wind hits your back, not your face. This moves airflow away from the front-facing mics.
• Cupping your hand slightly over the earbud mic area reduces direct wind exposure.
• If available in your app, enable wind noise reduction in call settings.
• Moving to any shelter — around a corner, under a roof — dramatically reduces wind noise more than any processing.

For professional or important calls outdoors in wind, a wired earbud with an inline microphone positioned close to your mouth outperforms wireless earbuds consistently — physical proximity to your mouth is a bigger advantage than software processing.

Which earbuds actually sound best on calls

Jabra Elite series: Jabra makes professional communication hardware and applies that expertise to consumer earbuds. The Elite 4, Elite 8 Active, and Elite 10 consistently outperform equivalently priced earbuds for call quality. Beamforming mics and robust ENC make them the top choice when calls are a primary use case.

Apple AirPods Pro 2: Apple's microphone processing is excellent. The combination of the H2 chip, beamforming mics, and adaptive ENC makes calls remarkably clean. Best for iPhone users who want seamless integration.

Sony WF-1000XM5: Sony's call quality improved significantly from the XM4 generation. AI-driven noise suppression in the companion app helps. Not class-leading for calls but significantly better than most at the price.

Google Pixel Buds Pro 2: Google's machine-learning voice processing makes Pixel Buds particularly good for Android calls, with voice clarity algorithms optimised for Google ecosystem integration.

Bose QuietComfort Earbuds II: excellent ANC for comfortable call listening, average microphone quality for voice transmission. Better on the receiving end than the transmitting end.

Setting up your phone for best call results

The single most common reason earbuds underperform on calls is that the phone is using its internal microphone instead of the earbuds. This happens when Bluetooth auto-routing fails or when a previous app grabbed the audio input.

On iPhone: during an active call, tap the audio output icon (looks like a speaker or headphone symbol) and select your earbuds explicitly. This ensures the phone routes both playback and microphone through the earbuds.

On Android: most Android phones route automatically, but this varies by manufacturer. If call quality is poor, go to Settings → Connected devices → your earbuds and confirm they're set as the preferred device for calls. Some Android skins require per-app microphone permission for the earbuds to activate during third-party call apps like WhatsApp or Zoom.

For video conferencing apps (Zoom, Teams, Google Meet): check the audio input settings within the app. Many video apps default to the computer or phone's built-in mic rather than connected Bluetooth devices. Set the microphone explicitly to your earbuds within each app's audio settings.
