Published specification
What is true of this model and changes how you fix it
- Official specificationsBluetooth 5.4 with LE Audio — newer than the over-ear QC Ultra Headphones' 5.3. IPX4 rated. Battery up to 6 hours (Immersive Audio off) / 4 hours (on) per charge, much shorter than any over-ear model since it's earbuds; 20-minute quick charge gives about 2 hours. Wireless charging case supported.
- Type — ANC Bluetooth earbuds (battery)Bose's flagship earbuds with top ANC and Immersive Audio, in a charging case. Battery/ANC/Bluetooth and earbud-specific symptoms (fit, ear tips, case contacts) apply.
- Fit is criticalBose uses fit bands plus ear tips; ANC and bass depend on a proper seal. A CustomTune calibration runs at each insertion. Thin sound or weak ANC is usually the wrong tip/band size — try the other sizes.
- Case & batteryThe buds charge in the case; if a bud starts a session low, its case contacts may be dirty. Immersive Audio shortens runtime when on.
- FirmwareUpdated by connecting the charging case to a computer over USB and going to BTU.Bose.com. Bose says updates can fix minor bugs and improve device compatibility.

Exact questions
Questions that only have an answer for the Bose QuietComfort Ultra Earbuds
My Bose QC Ultra Earbuds have weak bass or the noise cancelling seems poor.+
Almost always the seal. ANC and bass depend on the ear tips and stability bands fitting your ears well — try the other supplied tip and band sizes until you get a snug seal, and let the CustomTune calibration run (the tone you hear when you insert them). A poor seal lets noise in and bass out. Clean the nozzles of wax too, since a blocked mesh muffles sound. Immersive Audio also uses more battery when enabled.
