iPhone 15 Pro Speaker Tips: Getting the Best Sound

The iPhone 15 Pro features a refined dual-speaker system with improved bass response and a wider stereo field. To get the most out of it, you need to keep both the bottom speaker and the earpiece speaker clean.

Use Earpiece Output mode

iPhones use the top earpiece speaker as the second stereo channel. SpeakerCleaner's Earpiece Output routes cleaning tones through this speaker too — most other apps only clean the bottom one.

Try the new Bass mode

The iPhone 15 Pro's improved low-end response means it benefits more from bass-frequency cleaning. Use Bass Mode monthly to clear out any deep debris.

Tune your custom presets

If you've upgraded from an older iPhone, you may need to recalibrate your custom presets. The 15 Pro's speaker is more sensitive — try lowering frequencies by 5–10% for the same effect.

Best case for sound

Cases that channel speaker output forward (rather than blocking it) make a noticeable difference. Look for cases with cutouts that match the iPhone 15 Pro's exact speaker positions.
