The tonal balance from any speaker is affected by its surroundings, and MP3 player speakers are no different. It will have more bass when placed next to walls than it will out in the open.
So that it will sound good in any situation - on an open table, back to the wall or even in a corner - Zeppelin incorporates custom tone shaping to adapt to them all. It’s easily accessed through the iPod's own menu system, where a new menu option called ‘Speakers’ is created when it is docked.


It is made for iPod, but a variety of other devices can play sound through Zeppelin and the bass level settings described in the Sound section are also applied to these devices. Both analogue and optical digital connectivity is supported by a common (AUX) socket on the back of Zeppelin.
Examples of other sources are:
- Other MP3 players, including early iPods without click wheel
- CD players - portable or static
- Portable radios with headphone or digital outputs.
- Computer direct
- Computer wirelessly using Apple Airport Express™
