In this video, I’m testing the NextSense Smartbuds—basically “sleep earbuds” that are designed to track what’s going on in your brain while you sleep—and I’m comparing the experience and the results to my Oura Ring. I walk through what sleep earbuds are, what makes the NextSense approach different, and how I actually used them night to night. This isn’t a specs-only breakdown; it’s about whether the data feels believable and useful in real life, and whether the product fits into a normal bedtime routine. I also dig into the sleep tracking analysis: what the Smartbuds report, how that lines up (or doesn’t) with what I’m used to seeing from Oura, and what surprised me when I compared the two. Finally, I wrap with who these are really for—because this kind of wearable isn’t a “one size fits all” purchase. If you’re curious about brain-based sleep tracking, want to know what it’s like sleeping with earbuds in, or you’re trying to decide between something like Oura versus a more specialized sleep device, this video will help you buy with confidence.
