Basically throw them out the &&^&^$^ window and get a new pair…. No im joking i have encountered an isssue in which the case is determined to be at a status of being dead, and even when put on charge there is no way the case is turning back on. Honestly will consider returning item. I will try fix tonight and if i do i will update you guys. Its just pretty $@$*!& that after 3 months, £200 bluetooth headphones can &&^&^$^ go through so many errors. Tbf it well feels like i have been &&^&@@ over by Apple but will find solution and update Yours truly, Callum Add snapchat @ziegcal if you can update me on a solution.
