Editor’s take

In favor

  • Same Muse meditation experience as Muse 2 with double the battery life
  • Soft fabric headband actually wearable lying down
  • Adds gyroscope, breath sensing, and a thermistor on top of Muse 2's stack
  • Sleep-focused programs unique to the S line

Against

  • Still only 4 channels — same coverage as Muse 2
  • Sleep staging is consumer-grade, not validated against polysomnography
  • Premium content gated behind separate Muse Soft / Muse+ subscription
  • Doesn't sit comfortably over glasses
