Reversing background‑noise intrusion in Amazon Echo Buds 2nd Gen

Understanding the Problem of Background‑Noise Intrusion

When you put on a pair of wireless earbuds, the first thing you want is a clear, intimate sound that isolates your ears from the world. Amazon Echo Buds 2nd Gen claim to deliver that experience with their proprietary Active Noise Cancellation (ANC) and Adaptive Sound Engine. Yet many users report that background sounds—traffic hum, office chatter, or a neighbor’s air conditioner—still bleed through. The issue isn’t just a lack of ANC; it’s how the earbuds balance transparency (so you don’t feel disconnected) with suppression (so you can focus on a single audio source).

The good news is that you can take a handful of steps to reverse this intrusion. The following guide explains why the problem exists, how the Echo Buds attempt to solve it, and what you can do—both with firmware and with a bit of manual tweaking—to regain the quiet you expect.


Why Echo Buds 2nd Gen Struggle With Background Noise

The Role of Adaptive Sound

The Adaptive Sound Engine (ASE) is designed to adjust the level of ANC on the fly. It analyzes the incoming audio through the built‑in microphones, detects whether you’re in a quiet environment or a noisy one, and then decides how much noise to cancel. In theory, this adaptive behavior is great because it keeps you from feeling “plugged in” when you want to stay aware of your surroundings.

In practice, the adaptation is sometimes too aggressive or too conservative. If the buds think you’re in a quiet room, they reduce ANC to allow ambient sounds in. But if that assumption is wrong—say, you’re on a busy street—the noise filter doesn’t compensate enough. Because the earbuds are small, the microphones can pick up a lot of external sound, making it difficult for the ASE to differentiate between useful ambient noise and annoying background hiss.

Hardware Constraints

Echo Buds 2nd Gen are priced competitively, which means Amazon had to balance cost, battery life, and size. The microphones are positioned close to the ear canal to provide a good signal for ANC, but that proximity also makes them more sensitive to external sounds. The digital signal processor (DSP) inside the earbuds can only run a limited number of noise‑reduction algorithms at a time. When you play music and also have a phone call or an Alexa command, the DSP prioritizes the primary audio source, leaving less headroom for noise suppression.


Built‑In Noise‑Reduction Features to Know

Before you tweak settings, understand the features already available on the Echo Buds:

  • Standard ANC Mode – Blocks out most low‑frequency ambient noise while allowing you to hear your music or calls.
  • Transparency Mode – Lets ambient sounds through for situational awareness.
  • Adaptive Sound – Automatically switches between ANC and Transparency depending on detected noise levels.
  • Bass‑boost and Voice‑enhance settings – These can alter the audio spectrum in ways that either help or hurt background noise reduction.

All of these are accessible through the Alexa app or the companion Echo Buds app. However, the default settings are not always optimal for every environment.


Updating Your Firmware

A common cause of background‑noise issues is running an outdated firmware version. Amazon frequently releases updates that refine the noise‑cancellation algorithms, improve battery performance, and add new features.

  1. Open the Alexa app on your smartphone.
  2. Navigate to Devices → Audio Devices → Echo Buds.
  3. Check the firmware version displayed.
  4. If an update is available, tap Update and follow the prompts.
  5. Allow the earbuds to fully charge before testing again.

Firmware updates are free and usually fix a range of issues, so make this step a priority before moving on.


Manual Settings Tweaks

Fine‑Tuning ANC Levels

The Echo Buds 2nd Gen allow you to manually adjust ANC in the app:

  • Low ANC – Minimal cancellation, good for high‑noise environments where you still want some background context.
  • High ANC – Aggressive cancellation for quiet rooms or when you need to focus on your audio.

Switching between these settings can be done quickly and helps you find a sweet spot for your particular situation. Some users prefer to set High ANC in the office and Low ANC while jogging outdoors.

Adjusting Transparency Settings

If you want to keep an eye on traffic or conversation but still want the buds to block out noise, set Transparency to a moderate level:

  1. Go to the Echo Buds settings.
  2. Find the Transparency toggle.
  3. Select Medium instead of High or Low.

This balances situational awareness with privacy.

Modifying EQ for Voice Clarity

The built‑in equalizer offers presets such as “Bass‑boost,” “Vocal,” and “Treble.” The “Vocal” preset tends to amplify frequencies around 3‑5 kHz, making spoken words clearer. However, it also boosts some ambient hiss. Switch to a flatter EQ or create a custom curve that reduces frequencies where background noise is strongest (often around 400–800 Hz). This can lower the perceived hiss without compromising speech intelligibility.


Third‑Party Apps and Tools

While Amazon’s native app covers most needs, some users prefer third‑party solutions for more granular control.

  • Equalizer FX – Allows you to create custom EQ profiles for your earbuds.
  • Noise Cancelling App – Offers adjustable levels of ANC independent of the earbuds’ own algorithm.
  • Bluetooth Signal Analyzer – Helps you monitor signal quality and ensure no drop‑outs are causing background noise.

Before installing any third‑party app, make sure it’s compatible with Bluetooth Low Energy (BLE) and does not interfere with the Echo Buds’ firmware.


Hardware‑Based Adjustments

Proper Fit and Seal

A poor fit can let a lot of ambient sound leak in. Use the ear tips that came with your Echo Buds or purchase an aftermarket set designed for a tighter seal. A snug fit reduces the gap through which noise can enter and allows the ANC to work more effectively.

Cleaning the Microphones

Dust and debris can dampen the microphones’ ability to pick up the correct audio signal. Clean the small microphone openings with a dry, soft brush. Avoid using liquid cleaners or pressing too hard.


Step‑by‑Step Testing Routine

After making all the adjustments, follow this routine to verify improvement:

  1. Baseline Test

    • Put on the Echo Buds.
    • Record a 30‑second clip of background noise (e.g., office chatter).
    • Compare the recording to a phone call.
  2. Apply Settings

    • Switch to High ANC.
    • Record the same clip.
  3. Check Transparency

    • Switch to Medium Transparency.
    • Record the clip again.
  4. Use EQ

    • Apply the custom EQ curve that reduces 400–800 Hz.
    • Record the clip.
  5. Evaluate

    • Listen to each recording.
    • The best setting will show the clearest audio with the least background hiss.

Repeat the process until you are satisfied with the balance.


Troubleshooting Common Issues

  • Battery Drain

    • High ANC can increase power consumption. If your battery life drops noticeably, try a balanced ANC setting or disable Transparency when not needed.
  • Connection Drop‑outs

    • Ensure your phone’s Bluetooth settings are not set to “Low Power” mode, which can throttle audio bandwidth.
  • Persistent Hiss

    • If background hiss remains even after all tweaks, consider a factory reset. This will wipe the earbuds’ memory and return them to default settings, allowing you to reconfigure from scratch.

Maintaining Optimal Performance

  • Regular Firmware Checks

    • Set a reminder to check for updates every month.
  • Keep Earbuds Clean

    • Wipe the ear tips weekly and check for debris in the microphone openings.
  • Re‑Calibrate After Major Battery Drain

    • If the battery has dropped below 20 % for an extended period, fully charge the buds before testing.
  • Use in Moderately Loud Environments

    • Avoid exposing the earbuds to extremely loud noise (e.g., concerts, construction sites) for extended periods, as this can degrade the microphones.

Future Prospects for Noise Reduction

Amazon is likely to continue refining the Echo Buds’ ANC algorithms through firmware updates. In addition, we might see:

  • Machine‑Learning‑Based Noise Profiling – The buds could learn your typical noise environment and pre‑set the optimal ANC level.
  • Improved Microphone Arrays – More microphones might allow better directional filtering.
  • Integrated Room‑Acoustic Sensors – Sensors could detect ambient sound levels in real time for instant adaptation.

For now, though, following the steps above will give you immediate, noticeable improvement in reducing background‑noise intrusion.


Quick Reference Checklist

  • [ ] Update firmware to the latest version.
  • [ ] Adjust ANC to High for quiet spaces, Low for noisy ones.
  • [ ] Set Transparency to Medium for situational awareness.
  • [ ] Customize EQ to reduce 400–800 Hz frequencies.
  • [ ] Use proper ear tips for a tight seal.
  • [ ] Clean microphones monthly.
  • [ ] Test regularly with a simple recording routine.
  • [ ] Reset to factory settings if persistent issues occur.

By staying proactive and methodical, you can reverse background‑noise intrusion and enjoy the full potential of your Amazon Echo Buds 2nd Gen.

I doubt any software tweak will fix the bleed. The mic caps are physically exposed; you need a redesign.

The ANC system in the Echo Buds is a hybrid of feed‑forward and feedback loops. The feed‑forward mic captures external noise before it reaches the ear, while the feedback mic monitors the sound inside the ear canal. The DSP then creates an anti‑phase signal to cancel both low‑frequency hums and higher‑frequency chatter. If the adaptive engine isn’t trained properly, the cancellation curve will be off, leading to the bleed you’re hearing.

Your explanation ignores the fact that the Echo Buds use a hybrid ANC, not pure feed forward. The adaptive engine actually blends both signals to achieve a smoother cancellation across the spectrum.

I bought a pair of the 2nd gen Echo Buds about a month ago and tried everything the article suggested. First I turned on the adaptive sound, then I ran the calibration on the phone, but the traffic hum from the street outside my window still leaks in when I'm on a call. I even tried wearing them tighter and using the ear‑tips that came with them, but the mic still captures a faint background chatter. After following the firmware downgrade step I noticed a slight improvement – the hiss on the low end went down, but the mid‑range chatter is still there. Maybe the issue is hardware beyond my control, but at least the tweak helped a bit. Anyone else see a similar pattern?

Make sure you are on version 2.5.1 of the firmware; earlier builds have a known bug where the mic gain is set too high.

The buds have a hidden hardware switch you can flip to turn anc off completely – just pull the tiny tab on the left earbud.

There is no physical switch. The only way to disable ANC is through the Alexa app or by holding the button for 5 seconds.

The piece does a decent job laying out why the Echo Buds still let in city traffic noise. I think the main culprit is the side mic array being too sensitive when the ANC algorithm leans on the adaptive gain.
SO
Sofia 2 months ago
Actually the hardware design limits the low frequency cancellation. The only way to push it further is to modify the FIR coefficients in the DSP, which the stock firmware doesn’t expose. A custom build could re‑train the ANC model.

That's expected, the earbuds use a feed forward mic that picks up ambient air movement. You can't completely block a constant hum without a proper seal.
