Put my liberty Neo headphones in the washing machine by accident - please help

Hi there. I stupidly left my headphones in their case in my jogging bottoms and put them through a wash cycle in my washing machine!

When I realised, I left everything to dry for a few days before seeing if anything still works. The case still charges or at least the three lights go on and when I put the headphones in the case, a white light comes on with each one. However, when I remove them from the case - nothing, no lights or pairing.

Can anyone recommend anything else to try or am I just going to have to bin them? Such a shame as they were great headphones
