QC35
The kit whose title names QC35 and whose clip is that version's mount.
Bose QuietComfort ear cushions fit one version at a time. QC35, QC45, and QuietComfort Ultra do not share a mount. Name the model on the headphone, check that mount, and buy the cushion for that version only. A QuietComfort label without the version is not a match.
Read the model: QC35, QC45, or QuietComfort Ultra. Buy the cushion whose mount is for that version. Do not cross them. Check the fit note on the listing before you pay.
Each version's cup and clip differ. A cushion that fits QC35 is not the QC45 part, and Ultra is its own mount. Start with the name printed on the headphone.
Bose QuietComfort replacement ear cushions are a Bose ear cushion kit for one QC version. Compatible Bose ear cushions for your QC model follow that printed name: QC35 ear cushions, QC45 replacement ear cushions, and QuietComfort Ultra ear cushions are three parts.
Protein leather ear cushions for one Bose QuietComfort version and velour ear cushions for one QuietComfort version both wait on the clip. Soft foam ear cushions matched to your exact QuietComfort version are the same kind of match. Replace Bose ear cushions after you check that model's mount. OEM vs aftermarket Bose ear cushions for your QC version is a material choice after the clip agrees.
QC35 cushions use the clip for that version only. Do not order them from a QC45 title. Match the QC35 mount, then stop.
A QC35 ear cushion replacement is how you buy Bose QuietComfort ear cushions for this headphone. Compatible Bose ear cushions for your QC model still have to name QC35. QC45 replacement ear cushions and QuietComfort Ultra ear cushions are other mounts.
Choose QC35 ear cushions with the clip mount for that version only. QC45 ear cushions that are not the same as QC35 will not click on. Black protein leather QC ear cushions on the stock clips work when those clips are the QC35 pair. Protein leather ear cushions for one Bose QuietComfort version are the usual surface. Replace Bose ear cushions after you check that model's mount.
The mounts differ. A QC45 pair that looks similar will not clip onto QC35, and the reverse fails the same way. The title of the product has to name QC45 if that is the headphone.
QC45 ear cushions are the Bose QuietComfort replacement ear cushions for this version. Aftermarket Bose QC ear cushions are acceptable when the listing names QC45 and the clip matches. QC35 ear cushions and QuietComfort Ultra ear cushions do not take that place.
QC45 ear cushions that are not the same as QC35 stay on their own path. OEM vs aftermarket Bose ear cushions for your QC version can both be right. Protein leather Bose cushions thicker than the stock pair are a second choice, after the mount. Soft foam ear cushions matched to your exact QuietComfort version and black protein leather QC ear cushions on the stock clips follow that order: clip first, thickness second.
Ultra uses that model's mount only. Do not substitute QC35 or QC45 pads. This page does not link another QuietComfort cushion in their place. If the catalog has no Ultra cushion, there is no product link here.
QuietComfort Ultra ear cushions belong in a Bose ear cushion kit for one QC version, and that version is Ultra. Buy Bose QuietComfort ear cushions from a title that names QuietComfort Ultra. QC35 ear cushions and QC45 replacement ear cushions are the wrong clips.
Soft foam ear cushions matched to your exact QuietComfort version, velour ear cushions for one QuietComfort version, and OEM vs aftermarket Bose ear cushions for your QC version come after the Ultra mount is confirmed. Replace Bose ear cushions after you check that model's mount.
Compare the listing mount to the cushion you took off: clip shape, not just oval size. OEM and aftermarket are both valid after that check. Thickness is a second choice, not the fit.
Compatible Bose ear cushions for your QC model, aftermarket Bose QC ear cushions, and Bose QuietComfort replacement ear cushions pass or fail on that clip. Bose QuietComfort ear cushions cover QC35 ear cushions, QC45 replacement ear cushions, and QuietComfort Ultra ear cushions, and only one of those mounts is yours.
Replace Bose ear cushions after you check that model's mount. OEM vs aftermarket Bose ear cushions for your QC version can wait. Protein leather Bose cushions thicker than the stock pair, black protein leather QC ear cushions on the stock clips, and velour ear cushions for one QuietComfort version are surface and depth choices on the matching version.
Hold the cushion you removed next to the mount in the listing. The clip has to belong to the version printed on the headphone.
Does not decide fit
Size alone is not the check. A similar oval still fails when the mount belongs to another version.
A cushion for Sony, Jabra, or Samsung is its own part, even when it is also a round noise-cancelling pad. QuietComfort versions already differ from each other. Match the version you own, and keep those other cushions on their own mounts.
Buy the cushion kit for the one version you own. Leave QC35, QC45, and Ultra on separate paths. A product link is published only after the cushion fits that one QuietComfort version and the item is in the catalog. Nothing is linked from this page until then.
The kit whose title names QC35 and whose clip is that version's mount.
The kit whose title names QC45. A look-alike oval from QC35 stays on the other path.
The kit whose title names QuietComfort Ultra. QC35 and QC45 cushions are not linked here in its place.
No. Each version has its own mount. Buy the cushion for the model printed on the headphone.
Name the version, match that mount, then pick protein leather or velour and thickness.
Yes, when they use that version's mount. OEM is not automatically the better pad.
The clip or mount in the listing against the cushion you removed. Size alone is not the check.
Only on the matching version. Thickness does not make a QC35 pad fit a QC45.
The linked cushion fits that one QuietComfort version and is in the catalog.
