Are the POCO F7 speakers really that bad?

Why This Matters (UK Context)

For UK users, the POCO F7's speakers are most relevant for watching video, listening to podcasts, taking hands-free calls and gaming without headphones. If your F7 speakers sound off, the first question to answer is whether this is a normal characteristic of the device or an actual fault.

Speaker Hardware Overview

The POCO F7 uses a dual-speaker stereo system. The bottom speaker and the earpiece work together to provide stereo output.

POCO F7 Sound Quality Tested

Loudness

Notebookcheck measured a maximum loudness of 89 dB for the POCO F7, which is relatively loud for its class. However, one reviewer described the audio output as "not even close to the adequate bar" for gaming, where loudness matters for detecting audio cues.

Bass

The bass response is the device's most significant weakness. Notebookcheck found very weak low-frequency output, measuring approximately 24.7% below its smartphone median.

This is a measurement-based comparison, not a claim about perceived bass volume. In practical terms, the speakers sound thin, especially with bass-heavy music genres such as hip-hop, electronic, and rock.

Mids

The mids are slightly above the smartphone median and remain fairly linear, which helps keep vocals and dialogue clear. Subjective reviews generally describe vocals as intelligible.

Highs

The highs are well-balanced and linear, delivering crisp treble without harshness. This contributes to the POCO F7's good performance with podcasts, audiobooks, and video calls.

Stereo Separation

Stereo separation is present and functional. YugaTech noted that the bottom speaker "doesn't get blocked when holding the phone horizontally," which benefits gaming and video watching.

Some reviewers have observed slight channel imbalance at maximum volume, while others have measured the earpiece as louder than the bottom speaker. This suggests that hybrid stereo designs can behave differently between test setups and units.

Is the POCO F7 Speaker Actually Faulty?

Before running through troubleshooting steps, use this table to determine whether what you are hearing is a normal characteristic or an actual fault:

The Dolby Audio Bug (What Buyers Should Know)

Some POCO F7 users reported Dolby Audio quality issues following a specific HyperOS build. According to the Xiaomi Miui Hellas HyperOS bug report, the affected build was OS3.0.5.0.WOJMIXM on the Global ROM.

The problem caused "non-ideal" Dolby Audio performance. Xiaomi confirmed that the issue was software-related, not a hardware defect, and stated that a fix from Dolby Laboratories was being tested for release through a future software update.

How Good Is the POCO F7 for Everyday Use?

POCO F7 Speakers Too Quiet or Sound Bad?

If your POCO F7 speakers sound quieter than expected or produce distortion, try these steps in order:

1. Check for HyperOS updates:
   Settings → About phone → System updates
   Dolby Audio fixes are distributed through monthly software updates.
2. Toggle Dolby Atmos off and on:
   Settings → Sound & vibration → Dolby Atmos
   Compare the sound with it enabled and disabled.
3. Check the media volume level:
   Press the volume up button during playback. Media volume is separate from ring and notification volume.
4. Check the speaker grille:
   Inspect the bottom speaker for dust, lint, or debris. Use a soft brush to clean it gently.
5. Test another source:
   Play a different video or music file to rule out a problem with the content itself.
6. Restart the phone:
   A simple restart can clear temporary audio glitches.
7. Test in Safe Mode:
   If persistent distortion or abnormal behaviour continues, boot into Safe Mode to rule out a third-party app conflict.

How to Improve POCO F7 Sound

1. Enable Dolby Atmos:
   Settings → Sound & vibration → Dolby Atmos → Toggle ON.
2. Adjust the equaliser (if available):
   Settings → Sound & vibration → Sound effects. Boost bass frequencies if desired.
3. For gaming:
   Use wired or Bluetooth headphones to compensate for loudness limitations.
4. For music:
   Use headphones supporting high-quality Bluetooth codecs for better audio fidelity.

What Reviewers Say

Reviews are mixed, with some praising loudness and clarity while others criticise bass. This reflects differing expectations and use cases.

Final Verdict

The POCO F7 speakers are not "bad" — but they are not great either. For everyday use like podcasts, YouTube, calls, and casual video, they perform well, with clear vocals and adequate loudness. The mids and highs are above the smartphone median.

Two issues hold them back:

1. Weak bass: measured at approximately 24.7% below the smartphone median.
2. Dolby Audio bug: a software issue tied to a specific HyperOS build, for which Xiaomi confirmed a fix was being tested.

For UK users seeking a mid-range phone for general media consumption and communication, the POCO F7's speakers are sufficient. For audiophiles or heavy gamers, they may fall short of expectations — headphones are a better option.
