Thanks for reaching out to the community.
The QuietComfort 25 ear cushions are not compatible with the AE2i headphones. You will require the AE2 cushion kit. I would recommend that you reach out to your local product support team where an agent will be able to set up an order for you. Our local support team can be contacted via clicking this link and selecting your region, this will redirect you to our website. Please scroll to the bottom of the website and there you will find a 'Contact Us' tab, this will provide you with all the relevant contact information for your country.
Do let us know if you have any further questions.
