How to Set Up Samsung Galaxy Buds4 Wireless Earbuds

Remove the Galaxy Buds4 earbuds and charging case from their packaging. Check that the charging contacts and protective films are clean and remove any transport film.
Place both earbuds in the case and connect the case to a USB-C charger. Allow the earbuds and case to charge before extended use.
Open the case near an unlocked Samsung Galaxy smartphone or tablet. Follow the on-screen pairing prompt when it appears.
If the prompt does not appear, open Bluetooth settings, select the Galaxy Buds4 from the available-device list, and confirm pairing.
For configuration, use the available Galaxy Buds settings to adjust noise control, Ambient Sound, equalizer preferences, touch or pinch controls, 360 Audio, voice detection, and notifications.
For another phone or computer, place the earbuds in the case, leave the lid open, and use the device’s Bluetooth menu to select the earbuds. If they do not appear, restart Bluetooth and try again.

Keep the earbuds dry while charging, and never charge them when the USB-C port or charging contacts are wet. Do not use excessive force when inserting the earbuds into the case. When pairing fails, close and reopen the case, restart Bluetooth, and remove an outdated Galaxy Buds4 entry before pairing again.

Samsung Galaxy Buds4 Troubleshooting Guide

Earbuds will not connect

Confirm that Bluetooth is enabled and that the earbuds are within a short range of the device. Place both earbuds in the case, close the lid briefly, reopen it, and try pairing again. If the earbuds remain unavailable, forget the existing Bluetooth entry and repeat setup.

Only one earbud produces sound

Check that both earbuds have battery power and are seated correctly in the charging case. Clean the speaker grille and charging contacts with a dry, soft brush. Confirm left and right audio balance in the connected device’s accessibility settings.

Audio cuts out or sounds distorted

Move away from heavy wireless interference, keep the connected device nearby, and pause downloads or other demanding Bluetooth connections. Clean the earbuds and verify that the selected audio codec and software are supported by the connected device.

Noise cancellation or Ambient Sound performs poorly

Reposition the earbuds securely and check that microphones are not blocked by dirt. A poor fit can reduce both noise isolation and call quality. Test the feature in a quieter environment after cleaning.

Charging problems

Clean the contacts, check the USB-C cable and charger, and ensure the case is dry. Avoid extreme temperatures. For persistent faults, contact Samsung support or an authorised service centre using the regional support information supplied with the product. Warranty coverage depends on the purchase region and the nature of the fault.

Limitations

Best features require compatible devices: Some high-resolution, spatial-audio, and ecosystem functions depend on Samsung hardware and software.
Battery life varies: ANC, call usage, codec selection, volume, and other settings can reduce the stated maximum playback time.
Not waterproof: IP54 protection does not make the earbuds suitable for swimming, showering, or submersion.
Fit remains personal: Users who prefer sealed in-ear tips or a different earbud shape may need another product category.
