For Huddy, performing wouldn't be the same without his Ultimate Ears in-ear monitors. He calls his particular set "irreplaceable," explaining that they're more than just equipment — they're what hold every performance together.
"You hear everything that goes into the show," he says. "Things are moving at a million miles an hour, so your in-ears are what keep you focused." Whether he's rehearsing or performing live, his in-ears are the key to staying connected with his band, his music and the crowd.
