True about the battery life. But I can't fit the rendition one and a DAP into a pocket. I guess the term 'portability' has a much more generous usage among audio enthusiasts.
PS I believe the Heir 5.0 has a new rival on the market, in the form of the new Shure SE846! Let the battle commence. Anybody own both?
