    NOTE: Each earbud is marked with either an R (right) or L (left).Bose QuietComfort Ultra Earbuds User Manual-fig 8
  2. Slightly rotate the earbud back until the ear tip creates a comfortable seal at your ear canal and the stability band rests against your ear ridge.
    NOTE: You may need to rotate the earbud back and forth for the ear tip to create a comfortable seal. However, rotating it too far back or forward may impact audio and microphone sound quality.Bose QuietComfort Ultra Earbuds User Manual-fig 9
  1. Check the fit (see page 15).

CHECK YOUR FIT

For the best fit, audio performance, and noise cancellation, use a mirror to make sure you’re using the correct size ear tips and stability bands. You may need to try a  different size ear tip or stability band for each ear.

Stability bandsBose QuietComfort Ultra Earbuds User Manual-fig 11

TRY ANOTHER SIZE

Wear the earbuds for an extended period. If the earbuds don’t feel comfortable or secure, or noise cancellation or sound quality isn’t as expected, try another size ear tip or stability band. You may need to try all three ear tips or band sizes or use a different size ear tip or band for each ear.

Eartips

Three sizes of ear tips are included with the earbuds: small, medium, and large.Bose QuietComfort Ultra Earbuds User Manual-fig 12

Medium ear tips come attached to the earbuds. If they feel too small, try large ear tips. If they feel too big, try small ear tips.

  3. Gently stretch the band over the ear tip, making sure the dots align and the tab on the band fits in the notch on the top of the earbud.
    NOTE: Aligning the band correctly makes sure that the hole on the side of the band is over the earbud microphone so the microphone isn’t blocked.

It feels like the sound is coming from outside the earbuds, resulting in a more natural listening experience. Immersive audio works on any streaming content from any source, taking it to new heights with better sound clarity and richer sound quality.
