Opening the box for the first time? Here's everything you'll find inside your QuietComfort Ultra Earbuds 2nd Gen.
The Main Stuff
The earbuds — Left and right, already set up with medium ear tips and size 2 stability bands (the wings that help them stay in your ears).
The charging case — Works with wireless chargers and USB-C. Has an LED on the front to show battery status.
The Fit Kit
Bose knows everyone's ears are different, so they include options:
Ear tips — Three sizes (small, medium, large). Mediums come pre-installed. These silicone tips include rubberized guards (new in the 2nd Gen) that help keep earwax from building up on the speakers.
Stability bands — Three sizes (1, 2, 3). Size 2 is pre-installed. These concha fins hook into your ear's curve for a secure fit.
The Cable Situation
You get a short USB-A to USB-C cable—about 12 inches. Enough to reach from a laptop USB port.
What you don't get: A wall adapter. Bose assumes you have one already (you probably do). Also no USB-C to USB-C cable, so if your laptop only has USB-C, you'll need your own.
Getting the Right Fit
This matters more than you might think. The wrong fit means weaker bass and less effective noise cancellation.
Start with pre-installed sizes. If the seal feels loose or bass sounds thin, try larger tips. If earbuds feel unstable during exercise, adjust stability bands. Many people find mixing sizes works best—like large tips with medium bands.
