Stop tracking bad sleep.Start improving it.
Your tracker tells you what's wrong. NextSense actually helps you sleep deeper — with brain-sensing technology and adaptive audio designed to slow your mind down and keep it down.
- Brain-sensing tech, not wrist guesses
- Adaptive audio that slows your brain down
- Sleep on it 30 nights — risk-free

Knowing you slept badly doesn't help you sleep better.
Wrist trackers and rings score your night based on movement and heart rate — then leave you with a red number and no plan. You wake up tired, see another bad score, and start the day worse than you ended it. Tracking isn't a solution. It's just a receipt.

Reads your brain — not your wrist.
NextSense uses in-ear sensors that pick up signals directly from your brain. That's how sleep is measured in actual clinical studies — not estimated from wrist movement. The result: you get real data about your sleep, and the buds use that data to actually help you sleep better.

Sleep audio that responds to you.
Because NextSense reads your brain in real time, the audio adjusts to where you are in your sleep cycle — slowing your mind down when you're trying to fall asleep, masking disruptions when you're drifting off, going quiet when you're already deep. Most trackers tell you when you woke up. NextSense helps keep you from waking up in the first place.

Built to improve sleep — not just measure it.
Other devices track. NextSense intervenes. Brain-sensing tells the buds when you're drifting off, when you're restless, when you're deep. The audio adapts in real time to keep you asleep longer and deeper. Wake up with data that actually means something — and a night that actually felt better.
My Oura ring told me I had bad sleep every morning for two years. NextSense is the first thing that's actually changed the score. Deep sleep up nearly 40% in three weeks.

Built by the team behind Google's most ambitious sleep research.
NextSense started as a moonshot inside Alphabet's X. After years of brain-sensing research and clinical sleep studies, the founding team spun out to bring the technology directly to people who'd been tracking bad sleep for years without anything actually changing.
I've been a Whoop subscriber for three years. Every recovery score told me I needed more sleep. None of them helped me actually get it. NextSense did, in the first week.
