Why Your Earbuds Sound Muffled During Calls and How ENC Fixes It
If you’ve ever been on a call where the other person keeps saying, “I can’t hear you clearly,” or you find your voice sounding muffled and distant, you’re not alone. It’s one of the most common frustrations for wireless earbud users today. The culprit isn’t always your voice or your connection — it’s usually your mic’s ability to filter background noise.
That’s where ENC (Environmental Noise Cancellation) comes in. Let’s break it down in simple terms and see how the Gibutech Ultra Open bone conduction earbuds take this technology to the next level.
✅ What Is ENC and How Does It Work?
ENC stands for Environmental Noise Cancellation. It’s a smart mic technology that helps your earbuds focus on your voice while filtering out surrounding noise — like chatter in a café, traffic, or the hum of an air conditioner.
Most ENC earbuds use dual microphones:
🔹One mic captures your voice directly
🔹The other picks up ambient noise
The earbuds then use built-in algorithms to reduce the unwanted background sounds and keep your speech crisp and clear for the listener.
So when you’re on a call in a busy space, ENC ensures the other person hears you — not the crowd around you.
✅ ENC vs ANC: What’s the Difference?
ENC often gets mixed up with ANC (Active Noise Cancellation), but they serve different purposes.
🔹ENC — improves outgoing call quality. It filters what the other person hears
🔹ANC — on the other hand, reduces incoming noise for you, the listener, by blocking ambient sounds during playback
Think of it this way:
🔹ENC helps your voice sound clear
🔹ANC helps your ears stay focused
The Gibutech Ultra Open earbuds combine open-ear comfort with powerful dual ENC microphones — perfect for those who take calls on the go and want to sound professional anywhere.
✅ Why Your Earbuds Sound Muffled During Calls
If your earbuds sound muffled, there are usually a few possible causes:
🔹Poor mic placement or design: Some earbuds don’t isolate your voice properly, especially in open spaces
🔹Weak Bluetooth signal: When your device connection drops, audio quality — especially for calls can suffer
🔹No ENC or basic noise suppression only: Without ENC, your voice competes with background noise, causing distortion or low clarity
That’s why earbuds with dual-mic ENC like the Gibutech Ultra Open make a difference — they’re designed to focus precisely on your voice, ensuring what you say is heard loud and clear, even if you’re walking by a busy street.
✅ The ENC Advantage in Gibutech Ultra Open Earbuds
