Sonically, I am very confident. It sounds very warm-spatially, but not badewannig-blechig. Very fine resolution I recognize details in songs that I have not so clearly perceived by other listeners. In forums I read that the depths are particularly pronounced, which deterred me from buying anything. One of my first earphone was the Koss The Plug and the bass from Koss was very strong, too strong for my taste, as I hear mostly instrumental music. The Shure SE215 has for my taste a very pleasant round, not dominant bass. Everything sounds very balanced. I must also say that this' so far are my expensive earphones. Included with it is a storage wallet with zipper and a small carabiner. On an inner side a net bag is attached. In total 6 pairs (each in sizes S, M, L) of silicone and foam eartips and a cleaning swab are included. I have not regretted the purchase and would not hesitate to recommend.
