Received my Massdrop Plus Universal IEMs last Friday and I am very happy with them. Been listening to music every chance I get since. With good isolation, I am experiencing listening at low volumes once again. The superb drivers deliver every audible note through out the entire sound spectrum. I also ordered the balanced cables and have an amplifier on the way. I really don't think the sound could get any better, but hey, life is about treading into ever deeper waters!
