NextSense Smartbuds vs Elemind
Smartbuds vs Elemind
Both use EEG and precisely-timed sound to change your sleep. The difference is what they change — and what you can stand to wear all night.
Try Smartbuds →The honest verdict
Elemind is real neurotechnology, not wellness theater: its headband reads your EEG and plays phase-locked pink noise to suppress the alpha waves that keep you awake, and the company reports that in its clinical trial 76% of subjects fell asleep faster. Respect. But Elemind's design centers on one moment — sleep onset. Smartbuds address the whole night: brain-guided audio to help you drift off, slow-wave support for deeper sleep once you're there, real EEG sleep staging you can review, plus nap, focus and meditation modes for the day. And they're earbuds, not a band strapped across your head.
| NextSense Smartbuds | Elemind | |
|---|---|---|
| Form factor | In-ear earbuds with soft tips + wings | Headband with bone-conduction speaker |
| Brain sensing | Clinical-grade in-ear EEG | EEG (forehead) |
| What it improves | Sleep onset + deep-sleep support through the night | Primarily sleep onset (alpha-wave suppression) |
| Sleep tracking | Full EEG-based sleep staging in the app | Limited — designed as an intervention device |
| Daytime uses | Naps, focus, meditation, calm | Sleep-focused |
| Audio | Built in; masks snoring and noise | Bone conduction tones |
| Price | From $199 | $349 |
Falling asleep is half the battle
If your only problem is the 40 minutes you spend staring at the ceiling, both devices attack it with the same underlying science — EEG-timed audio. But most people with hard nights also wake at 3 a.m., get too little deep sleep, or want to see what actually happened. That requires a device comfortable enough to stay on all night and smart enough to keep working after you're under — which is why we built the sensing, the stimulation and the sound into an earbud instead of a band.
Don't take our word for it
NYT Wirecutter's 2026 review of brain-wave sleep wearables called Smartbuds "the only in-ear EEG device for sleep assistance currently available" (read the review). Our in-ear EEG platform is built on peer-reviewed, clinically validated research — including a 2026 study in Bioelectronic Medicine conducted with Emory University. See the full clinical evidence.
Choose Elemind if…
- Sleep onset is your single, specific problem
- You cannot tolerate anything in your ear
- You prefer bone-conduction over in-ear audio
Choose Smartbuds if…
- You want the full night improved — onset, depth, and morning data
- You want to fall asleep to actual audio (and mask a snoring partner)
- You want one device that also handles naps, focus and meditation
- Headbands slide off or bother you
Frequently asked questions
Do Smartbuds and Elemind use the same science?
They share a foundation — reading EEG in real time and delivering precisely-timed audio to shift brain activity. Elemind concentrates on suppressing alpha waves at sleep onset; Smartbuds use brain-guided audio across the night, including slow-wave sleep support, and provide full EEG sleep staging.
Which is more comfortable to sleep in?
Comfort is personal. Smartbuds come with three tip and wing sizes and were designed for sleep, including side sleeping; most people adapt within one to two weeks. Headbands avoid the ear but must stay snug across your head all night to keep sensor contact.
Does either replace a sleep study?
No. Both are consumer wellness devices. Smartbuds' in-ear EEG platform is built on peer-reviewed research validated against clinical polysomnography, and can give you unprecedented nightly insight — but diagnosis of sleep disorders belongs with a clinician.
