Interesting! I am already in the HE-6 club, I sold all my other flagships once I really heard it well driven, for me it is just a total package. I was beginning to think the HE-1000 would be the same, only even better, but perhaps I had better audition them first!
I think this is also affecting non-Samsung devices, from what I have seen elsewhere. I guess some bug in the Lollipop implementation, rather than something Samsung-specific?UAPP still working though, correct?
I wouldn't describe the M2 as "boomy", I hate boomy myself. I think it's quite a step up from the originals. Much more comfortable for me than the PM-3, as I am also in the group who has discomfort due to the clamping force (alleviated a little by elongating them a bit more, less secure fit, but more comfortable).
