Symfony2 when listeners are preferable than services?

I know, that in most cases services preferable, because they are initiated directly at the call site and this approach making code more clear.

While harder to reason, what a system doing, when things are spread out over events.

  1. When using listeners is better than using services?
  2. How to use listeners and keep code clear?

Please, give some examples. Any help would be appreciated! Thanks a lot!

Listeners make sense when you create a reusable bundle/component that should not be modified by its clients but still be extensible.

Listeners don't make much sense for application code because they add a level of indirection that makes it harder to figure out what's going on.
