Works great with SM57 as it is made to fit size 57 exactly. Use this item if you plan to do a lot of vocal work with the 57. Keep in mind that the clamp screw is very small and you will need a precision flathead or jeweler's screwdriver to install it. Other than that it works great and looks a lot better on the mic than the big bullet sized windshields on SM58 sized mics. Highly recommended. And by the way, if you're on a tight budget, I highly recommend the SM57 for vocals and voice acting too. I also have an EV RE20, a Shure SM7b and a Procaster and this mic can hold its own against any of them for a fraction of the cost! If you look online you will see many people agreeing with this, including some established mic tests.
