NextSense Launches EEG Smartbuds
NextSense has announced the official launch of the NextSense Smartbuds, a sleep device that uses six EEG sensors to measure brain activity in real time — then respond with timed audio stimulation to guide the brain into deeper, more restorative sleep.
Unlike trackers that infer sleep from motion or heart rate, Smartbuds use EEG sensors to detect when users are entering light sleep, deep sleep, or drifting awake. Over time, Smartbuds learn individual patterns, allowing nightly optimization and personalization based on a user’s own neural rhythms.
According to NextSense, early data shows Smartbuds deliver meaningful improvements in sleep quality for everyday users. In a controlled beta testing period over 106 nights, Smartbuds were shown to increase slow-wave activity. Additionally, nearly 50% of participants reported having “better” or “much better” sleep and improved morning recovery. Users also rated Smartbuds highly for comfort and audio quality, with 69% of those familiar with earbuds calling the sound superior. Across multiple beta cohorts, NextSense has collected over 1,000 nights of real-world EEG data, making it one of the largest in-ear sleep datasets outside a controlled study.
NextSense Smartbuds retail for $399.99 with a limited-time Early Bird launch price of $249. Smartbuds require an iPhone 12 or newer running iOS 17 or later. NextSense Smartbuds are now available for purchase on the NextSense website.
