    Travelers wanting an extra protective carry case.

  • First-generation Ozlo Sleepbuds

    Model: Ozlo Sleepbuds

    Earlier earbuds with up to 10 hours of use per charge, rather than the current generation’s longer battery life.
    Best for
    Buyers deliberately seeking the older generation.

Watch out

  • Sleepbuds 2 and first-generation Ozlo Sleepbuds are different generations. Check for the 2 in the listing.
  • The standalone set already has a charging case; a travel-case bundle adds a separate zippered case.
  • Ozlo Sleepbuds 2 is not Bose Sleepbuds II; the similar names do not identify the same product.

Why people pick it

  • 1.6 g buds with a low profile for side sleeping
  • Plays masking sounds or streams any Bluetooth audio
  • In-ear alarm wakes only the wearer

Know before you buy

  • No active noise cancelling: steady low rumble relies on the tips and masking sound
  • No microphone, so no calls
  • For streaming, keep the earbuds within 10 ft of the case and the case within 10 ft of the phone per the FAQ (less through walls); built-in sleep sounds and the alarm work without a connection
