Symptoms
- Voices sound thin, sharp, or lacking bass
- Sound is fine on media playback but tinny on calls
- Effect is more noticeable through certain headphones
- No distortion, just a thin quality to the sound
Likely causes
- CommonSmall earpiece speaker naturally limited in bass responsePhone earpiece speakers are physically small and designed for clarity over full sound range, which can sound tinny.
- CommonBluetooth headset's sound profile emphasizing trebleSome Bluetooth accessories are tuned brighter, which affects voice calls more noticeably than music.
- PossibleAccessibility sound enhancement setting activeSome phones have a 'voice clarity' or similar feature that boosts higher frequencies for better speech understanding, which can sound tinny.
- PossibleEqualizer setting favoring trebleA custom or app-based equalizer setting can shift the sound balance.
- Less commonSpeaker or headphone hardware limitationLower-quality speakers or headphones may simply lack the range for a fuller voice sound.
What to do
- Test the call on speakerphone versus earpiece to compare the sound quality.
- Check Settings > Accessibility for any voice enhancement or clarity features and try toggling them.
- If using Bluetooth headphones, check the manufacturer's app for an equalizer setting and adjust toward more balanced or bass-boosted.
- Try a different pair of headphones or earbuds to compare the sound signature.
- Reset any custom equalizer settings back to default in the phone's sound settings.
- Ask if the caller's audio sounds the same to them, which would suggest it's a device-side preference rather than an issue.
- Update Bluetooth accessory firmware if available.
- If the tinny sound bothers you significantly, consider higher-quality headphones designed for voice clarity.
