I have been using them quite a lot the past week, because I'm making a few journeys to London a week. So have been using them for about 3-4 hours a day. They are so comfortable to wear for all that time, and I now get them in within about 5 seconds, and it doesn't take much longer to get them out. They are so good, on the train they do block a lot, even when listening to quiet ambient/classical music there is still a lot of ambient noise blocked out on the train. The only thing I find that is on the right ear, it slightly fits less deep in the ear (not the canal portion, but the bit near the plate). I don't notice any sound difference, or isolation (so I don't want to mess with adjustment etc). Because it only seems to be affected when I'm rushing around (but most the time I use them I'm sitting on the train, so not to worried), or eating lol (is when I notice it isn't such a deep fit). Also really nice to listen to louder/heavier music like nadja, they do sound great! Generally using the X5L at about half the volume (6-8) I was before with my e2c, and 1/3 of the volume I was with earbuds

Definately worth the money. Did you decide whether or not to send them for adjustment rav? I think it would just be an ongoing procedure if I decided to do that, ie having to send multiple times (because it's not like we can just go in, and let them do it for us to try on site lol) and I don't notice any difference in comfort or isolation so I'm happy
