Tone Buds 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 monthly to maintain peak performance and ensure accurate brainwave readings.

Yes, Tone Buds 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, Tone Buds 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, Tone Buds use EEG, measuring your brainwaves directly for a more accurate picture of your sleep.

Without the Tone App, Tone Buds 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 Tone Buds, however, the Tone app is essential. It helps you monitor sleep pattern and provides personalized tips for better rest and alertness throughout the day.

 Yes, Tone Buds 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. You can learn about the safety of prolonged EEG exposure here.

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.
