Now how to listen to the Koran offline without an internet connection to listen.
Just open the Quran and choose the Surah of the Quran.
An mp3 file will be played and you can listen to the Qur'an for a long time.

Each letter will be played back to back automatically. There is no need to tab again and again on each Surah and in this way you can listen to the Complete Quran offline.
