Everyday wireless earbuds

Samsung Galaxy Buds3 FE SM-R420NZAAXAR are true-wireless in-ear headphones built for daily listening and calls. Active noise cancelling reduces ambient sound while a binaural design delivers stereo audio. Integrated microphones support voice assistants including Gemini, Alexa and Cortana. The grey finish and water-resistant rating suit commute, office and light exercise use.

Pairing and fit guidance

Automatic pairing connects the buds to a compatible device once the case lid opens. Select the included ear-tip size that creates a secure seal; a loose fit degrades noise cancelling and bass response. Clean the charging contacts on both buds and case weekly to prevent intermittent charging. Touch controls handle playback, calls and voice-assistant activation without removing the phone from your pocket.

Compatibility and power checks

Verify your phone or tablet supports Bluetooth audio and the SmartThings app for firmware updates and feature settings. The case charges via USB-C; ensure you have a suitable cable and power source. Each bud weighs approximately 0.18 oz (5 g) and provides up to 4 hrs of continuous communication time, with the case extending total operating time to 30 hrs.
