There is no problem with the tablet Lenovo created a fantastic product. I thought Tevas were a bit better quality than this. I am going to try it a few more time to see it the issue comes up again. Overall not my favourite wireless speaker but will keep it for going to the beach etc instead of using it at home for listening to music! It never occurred to me that buying replacement rubber earbud tips was even possible! As an IT consultant I need fast switching. These are simply brilliant and the sound quality is what I?ve wanted for so long , even better than any big headsets . Truly for the price. Real birks that came quickly! It protects my Audio Technica ATH-M50 headphones.
