How to Clean Bose QuietComfort Ultra Headphones
Bose QuietComfort Ultra Headphones collect skin oil on their ear cushions and headband while dust settles around microphone openings, controls, hinges, and the USB-C port. Bose's headphone-care guidance permits carefully removing ear pads and cleaning them with a lightly dampened soapy cloth, but the electronics and openings should not be saturated. Cushion attachment also matters: an incompletely seated pad can change comfort, acoustic sealing, and noise-cancellation performance.

Step-by-step instructions
Step 1: Power off and unplug everything
Turn the QuietComfort Ultra Headphones off, disconnect USB-C and audio cables, and remove them from their case. Fold or rotate the ear cups only through their normal range. Do not clean while charging. Keep free liquid away from microphones, speaker openings, controls, status lights, hinges, cable jacks, and the charging port.
Step 2: Remove loose exterior dust
Use a soft dry lint-free cloth across the ear cups, yokes, headband, and controls. Brush dust outward from seams and hinge edges without driving it into an opening. This dry first pass prevents grit from scratching finishes during damp wiping. Do not use an abrasive pad, household polish, solvent, or aerosol cleaner on the headphones.
Step 3: Remove each ear cushion carefully
Follow the QuietComfort Ultra manual and Bose guidance, beginning at the indicated edge and gently pulling the cushion mounting lip or clips away from the ear cup. Work around gradually instead of yanking one point. Do not insert a screwdriver or bend the cup flange. Note the cushion orientation and do not disturb internal acoustic fabric.
Step 4: Clean the ear cushions
Lightly dampen a clean cloth with mild soapy water and wring it thoroughly. Wipe the cushion surfaces and mounting edge without saturating the foam or allowing water inside. Use multiple gentle passes on skin oil rather than scrubbing the coating. Follow with a second cloth barely dampened with clean water, then blot dry.
Step 5: Wipe the headband
Use a dry cloth first. For residue on a compatible headband surface, use a lightly dampened soapy cloth following Bose's material-care guidance and prevent moisture from reaching sliders and hinges. Wipe away soap with a fresh barely damp cloth and dry. Do not soak, twist, or machine-wash any attached headband padding.
Step 6: Clean ear cups and controls conservatively
Wipe the outer cups and button surfaces with a soft dry cloth. For a persistent exterior mark, use minimal moisture on the cloth rather than spraying the device, then dry at once. Keep liquid off the inner driver fabric and electronic openings. Do not attempt to remove fixed internal screens or push a cloth into the ear cup.
Step 7: Clear microphone and port edges dry
Use a dry soft brush or cotton swab around accessible microphone openings and port entrances. Move debris outward and avoid inserting anything into a hole. Do not use compressed air, putty, a pin, or liquid. If a microphone remains muffled after exterior debris is gone, use Bose troubleshooting rather than probing deeper.
Step 8: Dry cushions completely
Leave removed cushions and the disconnected headphones in a ventilated room until every cleaned surface and foam layer is dry. Do not use a hair dryer, radiator, direct sun, clothes dryer, or oven. A cushion can feel dry outside while its mounting seam retains moisture, so inspect the entire edge before reinstallation.
Step 9: Reinstall and test the seal
Align each dry cushion correctly and press around the complete perimeter until every clip or mounting section seats evenly. Run a finger around the rim to find gaps. Power on and test both channels, controls, microphones, and noise cancellation. An uneven sound or weak seal after cleaning often indicates a cushion edge that has not fully engaged.
