Can I really use in-ear monitors to mix or produce projects outside of my studio?

Yes. In-ears become your portable studio when you're not using them to perform on stage. Producer/Engineer Steve Wilk recently created one of his hits while working in a cafe. He says that in-ear monitors "give me a studio with no borders. Whether its a hotel lobby, a tour bus, or a plane, I can create music anywhere and I know that it will sound fantastic.”
