All in all, after several months of using it, I can strongly recommend the B & W Zeppelin Air. It’s a truly great iPod/iPhone speaker, filling even larger rooms with quite impressive depths and crisp heights. And in contrast to its competitors (e.g. think of the lousy hardware of the otherwise innovative Sonos speakers – what a pity!), you can see, feel and hear its excellent build quality. It’s been engineered by the guys who equip the famous Abbey Road Studios, supply the audio system for Jaguars and invented extravagant speakers like the Nautilus, after all.
The only thing which wasn’t satisfying so far, is the Zeppelin Air’s buggy default (software) implementation of Airplay, i.e. that the Zeppelin Air lost the Wifi connection after a while in stand-by mode. As I finally found out, all that’s needed to fix this is a firmware upgrade to version 2.00.24 [updated 20120930]. At least, my Zeppelin Air hasn’t ever lost its Wifi connection anymore since. So, if you experience Wifi connectivity issues with your Zeppelin Air (likely), don’t hesitate and upgrade the Zeppelin’s firmware now, although it’s somewhat cumbersome (you need a suitable USB cable, e.g. from an external hard drive or printer, as this isn’t included in spite of the Zeppelin’s upmarket price). It’s well worth it!
