sorry to hear this, it can be very frustrating, I've read many times in headfi forum of those ears that are not compatible with ciems... But why not instead of selling them, you exchange them for the universal version?
Its always a small percentage of users, it doesnt matter what brand but, dont be dissuaded by this. If you are in the UK, try going directly to ACS or ask them for recommendations on where to get your impressions, this is perhaps the most important part of the process. The majority of people that try ciems will stay with them, they are more comfortable than anything because they are molded to your ears and the sound, especially from TOTL is magical.
Go to your bathroom with the zx2 and the screen protector, close the door and turn the hot water for enough time that there is vapor covering the mirror(s), turn the water off, wait until the mirrors start to clear and enjoy your dust free room by putting the protector without a single speck!
Go for the encores if you prefer a more analogue sound with natural soundstage (a bit warm), and for the adels if you like it a bit brighter more punchier and open. Both are excellent choices, but just considering the price difference I would have a difficulty justifying the adels....
I must also stress the fact that you have to put ~150 hours before you make any conclusions, if you check older posts there are some descriptions of the sound changing dramatically and it was not my brain adjusting as I hardly used the while breaking them in. Good luck with solving the issues, all the effort will be worth it
