Your deepest, most restorative sleep happens during slow wave sleep—the stage linked to memory consolidation, physical recovery, and feeling refreshed the next day. But many people don’t get enough of it.
Smartbuds include a feature called Slow Wave Boost. Using EEG sensors, the buds detect when your brain naturally enters deep sleep. At just the right moment, they play a soft burst of pink noise—a sound similar to steady rainfall. Research shows this subtle stimulation helps your brain strengthen and extend slow waves, making deep sleep last longer.
The result: more restorative sleep, without you ever noticing it’s happening. The sounds are gentle enough that they won’t wake you, but precise enough to give your brain a boost when it matters most.
