Question Boya mice stopped working on Iphone6

[GeorgevanderwaltSA]

I have a Boya microphone which was working fine with my IPhone 6, But now it has stopped working. Any help with trouble shooting, or must I assume the Mice has gone bust?

First step to checking it, try it on another phone/tablet/computer see if it works anywhere.
