A listening course which is recorded by excellent native speakers in foreign recording studios. All the introductory speeches are narrated in your language, so you will know how to work with the individual parts.
You don’t need a computer or internet connection for listening. Any mp3 player or mobile phone is enough. You can therefore study while riding public transport, in a car, during various sports, while doing household chores, on vacation, or during your leisure time, thus using it even more effectively.
