You generally should not swim with Samsung earbuds, even if they have some level of water resistance. Most Samsung earbuds—like the Galaxy Buds series—come with an IP rating (such as IPX2, IPX4, or IPX7), which means they can handle splashes, sweat, or brief exposure to water. However, water resistance is not the same as waterproofing. Swimming involves prolonged submersion, pressure, and movement in water, all of which can force moisture into sensitive internal components and permanently damage the earbuds.
Even in cases where earbuds have a higher rating like IPX7 (which technically allows short submersion), manufacturers still don’t recommend using them for swimming. Chlorinated pool water or saltwater can also corrode internal parts over time. If you want audio while swimming, it’s better to invest in earbuds specifically designed for underwater use, as they are built to handle continuous immersion and harsher conditions safely.
