The smartbuds for better sleep

Smartbuds are scheduled to ship in Q3 2025. Pre-orders can be refunded at any time, and all purchases include a 90-day return policy starting from the date of delivery.

Smartbuds use Tecticoat™, an innovative dry electrode technology that eliminates the need for gels in EEG monitoring. Over time, the conductivity of this material naturally decreases. With your subscription, you’ll receive new sleeves periodically to maintain peak performance and ensure accurate brainwave readings.

We are currently accepting pre-orders for Smartbuds, available for shipping exclusively to the United States and Canada.

Yes, Smartbuds are designed for 24/7 use. During the day, they provide premium sound for music, podcasts, ambient noise, or any other audio experience of your choosing. Just make sure to charge them before bed for uninterrupted sleep.

Unlike traditional devices that passively track, Smartbuds actively respond to your brain state to improve your sleep in the moment. Moreover, most trackers rely on heart rate and movement sensors, which measure sleep indirectly and imprecisely. By contrast, NextSense Smartbuds use EEG, measuring your brainwaves directly for a more accurate picture of your sleep.

Without the NextSense App, Smartbuds will operate like most standard Bluetooth earbuds, allowing you to use them for calls and listening to music. To unlock all of the smart features of your Smartbuds, however, the NextSense App is essential.

 Yes, Smartbuds are built with medical-grade EEG sensors and are safe for daily wear. They’ve been rigorously tested to meet high safety standards, making them suitable for long-term use both day and night.

No. EEG measures the brain’s electrical activity, which can be used to determine sleep stage, but doesn’t capture or interpret thoughts. Still, we understand that brain data is highly sensitive and follow strict privacy standards. We never sell, share, or use your data without your explicit and enthusiastic consent.
