Jabra's guide is explicitly for the Elite 85h and demonstrates that its ear cushions can be detached. It supports replaceability of the target headset's cushions, but does not independently certify the Brainwavz product.
Brainwavz explicitly identifies Jabra Elite 85H as the compatible model and says the pads are direct replacements that fit the existing clips. Its product listing also gives the stated dimensions and product code BWAVZ-EP-JAB85H-PU-BLK.
