That's great! I have always enjoyed reading your reviews, I seem to look for the same things you look for in an IEM, so eagerly waiting for your review. Bought M1 and PL50 reading your reviews and I wasn't disappointed at all.
Did you select "Europe" as your region? That will set the volume to low. If you don't have Volume setting in settings(which should be set to high, if it's there) changing you region should fix it.
