No problem. I also recommend taking out the foam, and putting it back in but not all the way so that there will remain some space between the foam and the driver. That will let the driver move more air and will improve bass response and soundstage as well. Also, the treble can sound a bit overly pronounced for some people and with some music, especially while the RE0 are still not fully burned in. To tame the treble a little, just put a bit of cotton inside the nozzle.
