How to Get the Best Sound from Android and iPhone
Modern smartphones can deliver very good sound – if the right settings are used. Whether it's bass boost, clearer highs, or a balanced sound image: with the right audio options, you can improve the sound of headphones.
Basic Rule: The Source Determines the Sound
Headphones – just like speakers – can only reproduce what your smartphone delivers. Therefore, sound quality depends not only on the headphones but also on:
- the quality of the audio source (e.g., MP3, AAC, or FLAC)
- the set streaming quality
- audio and equalizer settings
- for Bluetooth: the codec used and transmission quality
Your Options for Sound Optimization
To optimize bass and sound on your smartphone, you have three main approaches:
- System audio settings on Android or iOS
- Sound options in music and streaming apps
- Separate equalizer apps
Which combination makes sense depends on your device and listening habits. It is important to use these functions purposefully and not excessively at the same time.
Let's look specifically at these points:
Android
Audio Settings for Better Headphone Sound
Use System Equalizer (device dependent)
Many Android smartphones have a built-in equalizer. Depending on the manufacturer, you can find it, for example, under:
Settings → Sound → Sound Effects / Equalizer
There you can:
- select sound profiles like “Pop,” “Rock,” or “Bass”
- manually adjust bass, mids, and treble
- activate additional effects like Dolby Atmos on some devices
💡 Tip: Usually, slight adjustments are sufficient. Extreme settings quickly lead to distortion.
⚠️ Important: Not every Android device has a system equalizer, and the functionality varies by manufacturer.
How an equalizer basically works and which frequencies influence the sound is explained very clearly by Teufel here:
Android Audio Amplifier: Not Intended for Music
The so-called audio amplifier (if available) in accessibility settings is not a sound improvement for music.
It was developed to highlight speech and ambient sounds for people with hearing impairments.
👉 This function is not suitable for music playback with headphones.
iPhone (iOS)
Targeted Headphone Sound Adjustment
On the iPhone, you can specifically adjust the sound under:
Settings → Accessibility → Audio/Visual → Headphone Accommodations
Here you can:
- distinguish between media and phone calls
- perform fine-tuning using hearing samples
- amplify soft frequencies
This function is especially suitable for headphones.
Use the iOS Equalizer
Additionally, you can activate a simple equalizer:
Settings → Music → EQ
Various presets are available here. However, manual frequency adjustment is not possible.
Music Apps
Improve Bass & Sound in Music Apps
Many music apps and players offer their own audio options such as:
- Equalizer
- Bass boost
- Pre-amplification
- Left/right balance
- Virtual spatial or surround effects
🎧 Tip:
Virtual spatial sound technologies can make the sound seem wider but do not replace real bass tuning.
⚠️ Even small changes to the equalizer can significantly increase bass. However, too extreme settings quickly lead to distortion.
Streaming Apps
Check Streaming Quality and Set Audio Quality
Besides all sound controls, the set audio quality in the streaming service plays an important role. Whenever possible, always enable the highest available quality – especially when listening with headphones.
For wireless headphones, Bluetooth transmission also affects the sound. The role of standards and codecs is described by Teufel here:
Equalizer in Streaming Apps
- Spotify or Deezer offer built-in equalizers with simple presets and only limited manual adjustments. These are suitable for quick sound adjustments but only partially suitable for detailed fine-tuning.
- Apple Music uses a system-wide equalizer
- YouTube Music and Amazon Music provide an EQ only to a limited extent
- TIDAL and Qobuz completely forego their own equalizers and require system or external solutions.
Separate Equalizer Apps
Separate Equalizer Apps – More Control, More Responsibility
With special equalizer apps, you can intervene even more precisely. Many apps offer:
- more frequency bands
- preconfigured headphone profiles
- individual sound adjustments
An exciting approach is personalized sound tuning based on your hearing, as described in the Teufel interview on sound personalization:
⚠️ Make sure not to use multiple equalizers simultaneously.
Conclusion:
How to Optimize Bass and Sound on Your Smartphone
If you want to optimize the sound of your headphones:
- Set the highest audio quality in your streaming service
- Use system or app equalizers moderately and purposefully
- Avoid extreme bass boosts and double sound filters
This way, you achieve a powerful, balanced sound without the sound seeming unnatural.
