Query: Very, very frustrating

The product details claim that with very little charging time the battery lasts for 15 hours. In fact with 8 hours charging time the battery lasts for 5 minutes.The product claims in it compatible with audible. Not True!!!The menu two or three slots each time you try to move one and for some inexplicable reason when you want to listen to music, or audio it keeps jumping back to record voicenotes.I am NOT a satisfied customer!
