Great to fall asleep to

These buds have some of my favorite fall asleep sounds that let me drift off consistently. EEG features are great! I love that I don’t lose my spot if I watch a show or listen to a book. I do feel more refreshed when using them, though they are so from traditional trackers. Pair well with Apple Watch or other low lift device to get intricacies of sleep.

Better rest days before busy days

I use NextSense buds a few times a week, particularly before stressful deadlines, important meetings, travel, or short nights. The soundscapes help me relax, and I appreciate being able to track my sleep afterward.

Phenomenal

Boosted my sleep, was able to sleep 3 hrs less and have same deep sleep. Great for meditation, love the soundscapes and really enjoy tracking my naps as well

Way too loud for sleeping

Unable to lower the volume, too noisy to sleep with. Seems to be a software bug when you launch sleep, the volume gets locked. Not comfortable as a side sleeper. Prefer the hatch even if it plays to the room. Really wanted to like this and was so curious about the metrics. Ugh, returning.

Doesn’t connect

the connection feature is buggy and doesn’t work so I can’t even use them. the small strips have been removed as instructed. case open. it doesn’t reliably flash for connection, and when it does, it still can’t connect. I’m fairly good with hardware and trying different approaches. don’t buy until they fix this. I will update my review when/if they do.
