Samsung Galaxy Buds4 SM-R540NZKAXAC Open-Ear Wireless Earbuds, Hi-Res Audio

Some listeners prefer earbuds with a sealed, tip-based fit, others want an open-ear feel for longer listening without frequent adjustments. The Samsung Galaxy Buds4 combine an open-ear fit with Hi-Res Audio and Adaptive Active Noise Cancellation, bringing detailed listening and adjustable noise control to music, calls, travel and everyday use.

Their redesigned fit is intended to sit comfortably for extended listening, while Adaptive ANC adjusts sound levels to suit your surroundings. That makes it easier to move between a quieter listening session and changing environments without relying on a fixed noise-control setting.

The open-ear design offers a different fit from earbuds that use ear tips, making fit preference an important part of the choice.

Compatibility

The Galaxy Buds4 connect wirelessly over Bluetooth and are listed as compatible with cell phones and tablets. Pair them with a Bluetooth-enabled device for listening to music or handling calls. Their touch controls provide a direct way to manage use without relying solely on the connected device.

Tips for day-to-day use

For a commute, a walk between appointments or an evening at home, the earbuds can move with you while Adaptive ANC adjusts to changes in the surrounding sound. Hi-Res Audio is a useful match for focused music listening, where fine details and layered textures matter. For calls and entertainment, the same Bluetooth connection works with compatible phones and tablets.

The open-ear fit is the key distinction to consider when choosing between this style and a design built around ear tips. If you value that fit and want noise control you can adapt to changing settings, the Galaxy Buds4 bring those priorities together. Touch controls keep common interactions close at hand, and the wireless charging case provides a place to store the earbuds between listening sessions.

Buyer feedback is mixed on overall quality, sound and value. Some listeners are satisfied with the sound, while others have different expectations, the Hi-Res Audio and adaptive noise-control features are useful points to weigh against your own fit and listening preferences.
