Rated 5 out of 5 by from The bass is unmatched I really wish it didn't have to be plugged in to function, but if you can get over that downside, this speaker is amazing. It looks classy and sounds classier.

Why hasn't Harmon/Kardon added support for Apple Music subscriptions for play over wifi? I can play them directly from the Apple Music app over wifi, but not through the controller app.. which keeps me from being able to control multiple speakers in home.

Asked by: J__lee
Unfortunately,&nbsp;Apple did not provide the added support to add Apple Music to the HK Controller App.
