Samsung Galaxy Buds4 and Buds4 Pro: Computational Design and Two-Way Audio 🎧

Published on February 27, 2026 | Translated from Spanish

Samsung renews its bet on wireless earbuds with the Galaxy Buds4 and Buds4 Pro. The strategy focuses on ergonomics, with a design based on studies of ear shape and simulations to achieve a stable fit. The series introduces a blade-type profile to improve grip and tactile controls, and a case with a transparent window. They are offered in two philosophies: in-ear (Pro) for isolation, and open (Buds4) for prolonged listening.

Two wireless earbuds with ergonomic 'blade' design. The Pro model (in-ear) and the standard (open) along with their case with transparent window.

Driver redesign and two-way architecture in the Buds4 Pro 🔊

The Pro model features advances in its audio system. It incorporates a larger woofer, whose internal redesign increases the effective diaphragm area by nearly 20% compared to its predecessor. This driver works in a two-way configuration, complemented by an independent tweeter. This separation seeks more defined reproduction, where bass and treble frequencies are managed by dedicated components, a technical approach uncommon in compact earbuds.

The universal ear: a dream made (simulation) reality 🤖

After thousands of simulations and a global ear study, Samsung seems to have found the definitive average shape. It's comforting to know that our ear pavilion is now data in an algorithm. The blade design promises a firm grip, almost as if the earbuds had decided to stay. All that's left is to hope that, among so many calculations, they haven't overlooked that small detail called sweat after a run.
