I have the V1 of these
They are great for music, providing you remember the final twist to fix them in your ears.
Connectivity slighty iffy sometimes but I'm 99% sure thats the iffy Huawei bluetooth stack on my Honor 10 as they are fine on my Ipad.
Nice to hear the Mic quality has improved - the V1's are friggin lousy for this - almost guaranteed to break up at some point during a 1hr Conf call. Although some reviewers claimed the V1's were ok for call too....
Getting more bang for the same buck - as the V1's were the same price - albeit slightly eye watering.
I also have a set of Jabra 65t's that I use for calls which are amazing, but absolutely lousy for music - sound like the bottom of the well.
