Customise Bose earbuds

I've never been able to get these to fit comfortably in my ear, no matter the size of the issued cushion I use. I took the inner part of the headphone off, moulded the sugru to fit the hook of the headphone, then applied a bit more to the top. I let it sit in my ear for an hour. I carefully took it out - and voila! A custom made, detachable headphone cushion. Axel.
