He never seems happy with inears always tweaking the levels gets mad adjusting them etc. Iam sure Micky is a style/ technique to save his voice but sounds much worse out of pitch and time due to in ear monitors causing a slight delay and with respect to the hard of hearing makes him sound like hes deaf on occasion. Try blocking your own ears and talk/sing.
My man Liam Gallagher from Oasis sang with them in 2009 when they broke up terrible year for his vocals we call that his kermit the frog phase. 100% improvement since ditching them. Helped to feel more present in the moment just a thought
