Galaxy Buds4 Pro Analysis: Advanced AI and Premium Features with Ecosystem Limitations

Samsung's Galaxy Buds4 Pro feature sophisticated capabilities, including robust artificial intelligence, efficient noise cancellation, and high-quality audio, promising top-tier functionality in a compact design. However, a detailed analysis reveals certain significant restrictions regarding the use of these earbuds.

Design and Durability

In terms of appearance, the Galaxy Buds4 Pro maintain a stem form factor, designed for a secure fit in the ear, and feature a plastic body with a discreet finish. They are certified with IP57, which ensures protection against dust and resistance to water immersion, making them suitable for use in the rain or during intense exercise. Users can replace the silicone tips, which come in three distinct sizes, to ensure the best personal fit.

The earbuds are controlled via the sides, allowing functions such as play, pause, or skip tracks to be activated by taps. These actions can be customized through the Samsung mobile device application.

Audio Quality and AI Features

Internally, the device uses two independent speakers—one dedicated to bass and another to treble—aiming to provide more balanced sound. If the standard sound is not satisfactory, the app provides a nine-band equalizer, giving the user complete control over frequency adjustment.

For phone calls, the microphone system works to filter background noise and clarify the voice. However, the effectiveness of this processing depends on the environment; in extremely noisy places, such as busy streets, perfect speech isolation can be challenging.

A central highlight of the Galaxy Buds4 Pro is the integration with Samsung's Galaxy AI. This AI enables features such as real-time translation and the ability to detect head movements to accept or reject calls. Furthermore, voice commands allow for music control without needing keywords, optimizing the user experience. Additional features, such as spatial audio and high-fidelity transmission, only operate when the earbuds are connected to other Samsung devices.

Samsung Ecosystem Limitations

It is crucial to note that many of these advanced functionalities are conditional upon having specific software on the smartphone, being restricted to users of Samsung Galaxy phones. This limits the appeal of the earbuds to consumers of other brands.

Connectivity also presents a limitation: the Galaxy Buds4 Pro establish a special link with Samsung devices, enabling automatic switching between a brand's laptop, phone, or tablet. This feature reinforces ecosystem dependency. On devices from other manufacturers, performance remains functional but is limited to the basic capabilities expected of a high-end pair of earbuds.

Support for the Auracast standard allows audio transmission to other compatible equipment in the same space, maintaining a stable connection over moderate distances.

Battery and Overall Performance

When removed from the charging case, the earbuds offer approximately six hours of playback with active noise cancellation on, or about seven hours with the function disabled. The charging case provides additional charges, extending the total usage time to around thirty hours. This autonomy is considered adequate for daily use, supporting daily commutes and long periods of work without the immediate need for recharging.

For charging, the device accepts both the standard USB-C port and wireless charging pads.

The positive points include the delivery of high-quality audio, the ability to customize equalization via the app, powerful noise cancellation, and proven resistance to dust and water, allowing for use in various contexts. However, the main caveat is that a large part of the advanced features is tied to the Samsung device ecosystem. While owners of Galaxy laptops, tablets, or smartphones will have seamless integration, users of other brands will find difficulties, as outside the Galaxy universe, the earbuds offer functionalities comparable to more affordable models.
