I just got my custom ER-25's today. They are fantastic. The only problem I'm having is that they seem to move around in my ear canal just a little bit, but enough that it seems like sound is getting around them when they loosen up. There is a very noticeable difference between when I have them in tight and when they loosen up a bit (which is within minutes). Are they supposed to be worn tight? As in, if I'm holding them tight to my ear, but not blocking the filter, is that how they are supposed to sound? Or is it actually the natural position for them to be a little bit loose? I am wearing them with the dots pointing downwards and in the correct ears. Thanks for any help you can give.
