Bring wireless personal audio to a phone, tablet or computer with Samsung Galaxy Buds4 in white. This configuration is an in-ear headphone set for Bluetooth audio, placing left and right listening channels at the user without requiring a wired headphone connection. Its compact two-earbud format suits everyday music, spoken audio and personal call use where a portable listening device is required. SM-R540NZWAXAR identifies the white Galaxy Buds4 configuration. Pair the earbuds with a Bluetooth-equipped source and use the pair as personal stereo headphones for individual listening. Selecting the stated color configuration matters where a white finish is required. The product belongs in the Galaxy Buds4 headphone range rather than a speaker, cable or mounting-accessory category. Galaxy Buds4 is the consumer-facing model designation, while the full Samsung code identifies the specific ordered configuration. Use the model name when recognizing the product family and the complete code when matching the requested white version. The unspaced searchable form, SMR540NZWAXAR, supports searches in systems that omit punctuation from Samsung ordering identifiers.
