How to Improve Audio Quality on Android

Audio quality on Android depends on four things: your source file, your playback software, your headphones, and your device’s DAC. Here’s how to optimize each one.

Start With the Source File

The most important rule: you can’t fix bad source material. A 128kbps MP3 will always sound compressed and muffled no matter what you do.

What I use for my personal collection:

Format	Use Case
FLAC (16-bit/44.1kHz)	Permanent archive, home listening
AAC 256kbps	Phone storage, commuting
MP3 320kbps	Compatibility with older devices

FLAC files are 5-10MB per minute, so they add up fast. I keep FLAC for albums I love and AAC for casual listening.

Configure Your Player Properly

A good music player matters more than most people think. The default Android audio mixer resamples everything to 48kHz, which can degrade quality if your source is 44.1kHz (which most music is).

Musiqly has a “direct output” mode that bypasses Android’s audio processing chain. This matters most when:

Playing high-resolution files (24-bit/96kHz)
Using an external USB DAC
Listening through wired headphones

Equalizer Settings That Actually Work

I’ve tested dozens of EQ presets across many headphone pairs. Here are the ones that consistently sound good:

For most pop/rock music:

Leave the EQ flat (all bands at 0dB)
Only cut frequencies that sound harsh, don’t boost

For bass-heavy music (EDM, hip-hop):

Boost 62Hz by +3dB
Boost 125Hz by +2dB
Leave everything else flat
Reduce pre-amp by -2dB to prevent clipping

For podcasts and audiobooks:

Cut 62Hz and 125Hz by -4dB (reduces rumble)
Boost 2kHz-4kHz by +3dB (improves vocal clarity)

The key insight I learned while building Musiqly’s EQ: cutting is better than boosting. Boosting increases noise floor and can cause distortion. Cut the frequencies you don’t want instead.

Invest in Good Headphones

This matters more than any software setting. A $100 pair of IEMs (in-ear monitors) with a $9 Apple USB-C dongle will sound better than $500 headphones running through a phone’s built-in headphone jack.

Budget options that sound great:

7Hz Zero 2 (~$25) — Amazing for the price
Moondrop Chu II (~$20) — Balanced sound signature
Truthear Hola (~$35) — Warm, easy listening

If you’re using wireless earbuds, enable LDAC in Android’s developer options. It’s the highest quality Bluetooth codec available. Go to Settings → Developer Options → Bluetooth Audio Codec → LDAC.

Turn Off Android’s Audio Processing

Many Android phones ship with audio “enhancements” enabled by default that actually degrade quality:

Dolby Atmos — Adds spatial processing that smears stereo imaging
Adaptive Sound — Adjusts EQ based on your environment
Volume Leveler — Compresses dynamic range

Turn all of these off in your device’s sound settings. They’re fine for phone speakers and cheap earbuds, but they reduce quality with good headphones.

FAQ

Does Bluetooth reduce audio quality?

Yes. All Bluetooth audio uses lossy compression. LDAC at 990kbps comes closest to wired quality. For critical listening, use wired headphones or a USB DAC.

What sample rate should I use?

Most music is 44.1kHz. Set your player to output at the file’s native sample rate rather than resampling. Musiqly’s direct output mode does this automatically.

Can I use a USB DAC with Musiqly?

Yes. Musiqly supports USB DAC output on Android. Connect the DAC, go to Settings → Audio → High-Resolution Output, and enable it.

Does a 10-band EQ really sound better than 5-band?

Yes, because it gives you control over narrower frequency ranges. A 5-band EQ adjusts broad swaths of the spectrum, which can affect frequencies you didn’t intend to change.

What’s the best audio format for Android?

AAC 256kbps offers the best balance of quality and file size. FLAC for archival. MP3 320kbps for maximum compatibility.
