Summary: At CES 2025, NextSense debuted its new consumer brand, Tone, and introduced Tone Buds, brain-sensing earbuds designed to improve sleep quality and optimize brain health. Equipped with clinical-grade EEG technology, Tone Buds monitor brain activity during sleep and provide real-time enhancements, including pink noise stimulation during deep sleep to promote restoration. The earbuds aim to address widespread sleep disorders and improve overall well-being.
Key Takeaways:
- NextSense Introduces EEG-Enabled Tone Buds: Tone Buds, equipped with clinical-grade EEG technology, monitor brain activity during sleep to analyze sleep stages and depth, offering insights into sleep quality.
- Real-Time Sleep Support: The earbuds use AI-driven pink noise stimulation during deep sleep to enhance slow-wave activity, a feature linked to improved nightly restoration and brain health.
- Practical Design for Sleep Tracking: Designed for comfort throughout the night, Tone Buds combine traditional wireless earbud features with tools for sleep monitoring and enhancement.
NextSense, the neurotechnology company building biosensing wearables for improved sleep and brain health, debuted its consumer brand, Tone, at the Consumer Electronics Show (CES) 2025 in Las Vegas.
Event attendees experienced Tone Buds, brain-sensing earbuds engineered to improve sleep quality and optimize daytime alertness through the integration of clinical-grade electroencephalography (EEG) technology.
“As a breeding ground for innovation, CES is the perfect opportunity to introduce Tone and our inaugural product, Tone Buds,” says Jonathan Berent, CEO and founder of NextSense, in a release. “Exhibiting brands are not only bringing new products to market but providing real opportunities to improve the way we live and advance humanity in meaningful ways. This ethos is at the core of who we are as a company, and we’re excited to be a part of the future of consumer technology.”
A reported 65% of American adults have trouble falling asleep, and 70 million have chronic sleep disorders. As poor sleep is linked to an increased risk of heart disease, stroke, anxiety, depression, obesity, and cognitive decline, among other health concerns, Tone by NextSense aims to increase access to its technology to help people better understand and improve their sleep to enhance both short- and long-term well-being.
By continuously monitoring brain activity, Tone Buds are designed to go beyond tracking to actively improve sleep in real-time. In addition to providing the expected functionality of a wireless earbud, Tone Buds use clinical-grade EEG technology to assess sleep stage and depth with precision unprecedented in a consumer product. In addition, the product has been designed to support all-night comfort in any sleeping position.
The AI-powered, closed-loop audio system responds to the user’s brain waves to anticipate their needs throughout the night—providing both audio for falling asleep and sound-neutralizing tracks to help users stay asleep. When Tone Buds detect stage N3 sleep, the deepest stage of non-rapid eye movement (non-REM) sleep, they emit subtle pink noise stimulation to augment the brain’s slow-wave activity, a technique scientifically proven to enhance nightly restoration.
