How to Improve Earbud Sound Quality | Fix Fit, Settings & More

The fastest path to better audio isn’t new hardware — it’s undoing the small things that quietly degrade what you already own. A poor seal from the wrong ear tip makes music sound thin and weak. A layer of earwax muffles detail and drops volume. Outdated firmware can introduce audio bugs. And most earbuds ship with a flat, neutral tuning that sounds dull until you adjust it.

Before you spend money on a new pair, work through the steps below. You’ll likely fix most of what’s wrong in under ten minutes. If you’re still left wanting afterward, see our tested picks for the best sound quality earphones to find a pair that truly fits your ears and budget.

Start With Fit: The Difference Between Thin and Punchy Sound

If your earbuds sound quiet, tinny, or short on bass, the ear tips probably aren’t sealing properly. A secure seal traps the sound waves in your ear canal, which is what produces full bass and consistent volume.

Try every tip size included in the box. The right size should feel snug but not painful, and it should stay put when you shake your head. Foam tips are worth trying if silicone doesn’t seal well for you — they expand to fill the ear canal, which often fixes both fit and bass response. For earbuds with wing tips or fins, test different sizes to make sure the bud sits evenly in your ear.

Samsung’s support guidance for its Galaxy Buds line specifically recommends trying different ear tips and wing tips to get a snug fit, and notes this is one of the first things to check when audio sounds off. Google’s Pixel Buds documentation says the same: a loose or uncomfortable fit changes what you hear.

Clean Your Earbuds: Earwax Is the Quiet Killer

A layer of earwax or debris over the speaker mesh is one of the most common reasons earbuds suddenly sound muffled, quiet, or unbalanced — usually with one side worse than the other.

Clean them the safe way:

• Use a soft, dry, lint-free cloth to wipe the exterior.
• Gently brush the speaker mesh with a dry, soft-bristled toothbrush or a dedicated cleaning tool — never poke anything into the nozzle.
• Remove and rinse silicone ear tips in warm water, let them dry completely, then reattach them.
• Keep earbuds away from moisture — Samsung explicitly warns against getting them wet during cleaning.

Both Samsung and Google include regular cleaning in their official audio-troubleshooting steps. If you notice volume dropping over time, a clean is the first thing to try before assuming the drivers have failed.

Update Firmware and Check Sources of Interference

Firmware updates are a recurring official fix for audio problems. Manufacturers regularly ship updates that correct Bluetooth bugs, improve codec behavior, and change tuning. Check your earbuds’ companion app — the Galaxy Wearable app for Samsung Buds, or the Pixel Buds settings — for a pending update at least once every few months.

Bluetooth audio degrades with distance and physical interference. Samsung’s own troubleshooting list includes moving your phone closer to the earbuds and reducing exposure to metals, walls, other Bluetooth devices, microwaves, and wireless routers. If your audio stutters or drops, walk closer to your phone and away from the router.

Use Your Phone’s Sound Controls to Tune the Audio

Most earbuds pair with a companion app that includes an equalizer. These presets change the sound signature dramatically.

Samsung’s Galaxy Wearable app offers six equalizer presets: Normal, Bass boost, Soft, Dynamic, Clear, and Treble boost. If music sounds flat, switch to Dynamic or Bass boost for more energy; if vocals sound buried, try Clear.

Pixel Buds users on Pixel phones (Android 10 or newer) can adjust sound by going to Settings > Connected Devices > your Pixel Buds > Sound. On other Android devices, use the Google Pixel Buds app. There you can adjust the bass level and turn on Volume EQ, which boosts bass and treble at lower listening volumes for a fuller sound.

A note on Bluetooth codecs: the audio quality your earbuds deliver depends on the codec both the phone and the earbuds support. SBC is the mandatory default that all Bluetooth devices support; AAC, aptX, LDAC, and LC3 are higher-spec options that only work when both ends support them. LDAC is common on Sony and many Android phones; AAC is standard on Apple devices. You can sometimes force a higher-quality codec in Android’s Developer options, but only if your earbuds support it — check the manufacturer’s product page before relying on it.

If you’ve tried the steps above and your current pair still doesn’t deliver, the hardware itself may be the limit. Our roundup of top-rated earphones for sound quality compares models that handle bass, detail, and codec support better.
