If you’re rocking a pair of OnePlus Buds 4, you’re already halfway to enjoying some truly impressive wireless audio. But if you really want to unlock their full sonic potential, diving into the world of custom EQ (Equalizer) settings is a game-changer. Whether you’re a bass head, a podcast lover, or someone who craves crystal-clear vocals, adjusting the EQ can personalize your audio experience far beyond the default presets.
This guide will walk you through everything you need to know to get the best sound from OnePlus Buds 4 using custom EQ settings, so your music sounds exactly how you like it.
Why Custom EQ Settings Matter for OnePlus Buds 4
Out of the box, the OnePlus Buds 4 already deliver solid audio performance with powerful bass and decent mids. But everyone’s ears—and tastes—are different. The default sound profile might not always match your preferred genre or use case.
By tweaking the EQ settings manually, you can:
- Boost clarity for podcasts or calls
- Enhance thumping bass for EDM or hip-hop
- Soften highs for smoother treble in classical or jazz
- Tailor a soundstage for immersive gaming or movie experiences
In short: custom EQ = customized listening bliss.
Step-by-Step: How to Access and Use Custom EQ Settings
1. Connect Your OnePlus Buds 4 to Your Phone
Make sure your OnePlus Buds 4 are connected via Bluetooth to your smartphone (preferably a OnePlus phone or any Android with HeyMelody support).
2. Download or Open the HeyMelody App
For users not using a OnePlus device, download the HeyMelody app from the Google Play Store or Apple App Store. This app gives you access to advanced settings and firmware updates for your earbuds.
Note: OnePlus phone users may find these options directly in the Bluetooth device settings under “Earbud Functions.”
3. Navigate to Sound Settings
Once your Buds 4 are detected:
- Tap on the earbuds from the connected device list.
- Look for “Sound Settings” or “Equalizer.”
4. Choose ‘Custom’ or ‘Personalized’ EQ
OnePlus usually offers a few preset EQ profiles like Balanced, Bold, Serenade, or Bass. Select the “Custom” or “Personalized EQ” option to begin manual tuning.
Recommended Custom EQ Settings for Different Audio Preferences
While tuning EQ is subjective, here are some helpful starting points based on your favorite audio style:
🎧 For Bass Lovers (EDM, Hip-Hop, Pop)
| Frequency | Recommended Adjustment |
|---|---|
| 60Hz (Bass) | +4 to +6 dB |
| 250Hz (Lower Mids) | +2 dB |
| 1kHz (Mids) | 0 dB |
| 4kHz (Upper Mids) | -1 dB |
| 8kHz (Treble) | +2 dB |
🔊 Tip: Don’t overdo the bass or you’ll lose clarity in vocals.
🎤 For Vocal Clarity (Podcasts, Acoustic, Pop Rock)
| Frequency | Recommended Adjustment |
|---|---|
| 60Hz (Bass) | -2 dB |
| 250Hz (Lower Mids) | 0 dB |
| 1kHz (Mids) | +4 dB |
| 4kHz (Upper Mids) | +3 dB |
| 8kHz (Treble) | +1 dB |
🗣 Emphasizing mids ensures speech and vocals come through cleanly.
🎼 For Balanced & Natural Sound (Classical, Jazz, General Listening)
| Frequency | Recommended Adjustment |
|---|---|
| 60Hz (Bass) | +1 dB |
| 250Hz (Lower Mids) | 0 dB |
| 1kHz (Mids) | +1 dB |
| 4kHz (Upper Mids) | +1 dB |
| 8kHz (Treble) | +1 to +2 dB |
🎶 This setting maintains audio fidelity across a wide range of genres.
Pro Tips to Get Even Better Sound
✅ Enable Dolby Atmos (If Available)
On supported OnePlus devices, Dolby Atmos can dramatically enhance spatial sound and audio depth. Toggle it on under Settings > Sound & Vibration > Dolby Atmos.
✅ Use High-Quality Audio Codecs
Check that your earbuds are using LHDC (Low Latency High-Definition Audio Codec) or AAC, if supported by your device. This ensures less compression and better sound detail.
✅ Update Firmware Regularly
The HeyMelody app often pushes firmware updates that fine-tune audio performance or add new features. Keep your earbuds updated for the best experience.
What to Avoid When Customizing EQ
- Overboosting multiple frequencies: This can create distortion and listening fatigue.
- Cranking treble too high: While it adds sparkle, too much treble can cause harshness.
- Setting all sliders equally high: This defeats the purpose of EQ—it’s not just about “louder.”
Final Thoughts
Customizing EQ settings on the OnePlus Buds 4 is one of the easiest and most impactful ways to elevate your audio experience. Whether you’re deep into bass-driven beats or want that podcast host to sound like they’re right next to you, EQ tuning puts you in control.
Take a few minutes to experiment with these settings—your ears will thank you.
