The fit is the same as the originals & they are very comfortable. Stopped working entirely after two weeks. I wont hold my breath though, and though people out there might want to know of one issue they may experience. They cut off outside noise very effectively. Adatta al periodo primaverile/estivo. I have used it for phone calls and worked without any issues or mic problems. 0/5 stars. Trust this post! I?ve bought probably 6 of these and plan on buying at least two more of the big ones. The MFG.
