As for me, this headset is used about three hours a day with a silent piano "Magic Star") (for the uninitiated, a digital piano installed inside of an acoustic piano and to play without disturbing its entourage). Comfort is essential for this type of use which also requires a certain freedom of movement. Very flexible materials used by the manufacturer (including wireless) enable not realize that we have a helmet on his head, which is essential for comfort. A second quality of this type of helmet is the purity and spatial effect of music listened. The piano (in my case a sampled Steinway) gives the impression to be at side of the helmet and not inside; the spatial effect is so perfectly rendered. This is an essential difference compared to other headsets, particularly that provided by the system manufacturer piano silent, yet very honorable quality. The use of stereo also has the same qualities. It is ideal for listening to classical music especially opera where the voice of the soloist must be returned pure and without saturation. I tested it with the voice of Roberto Alagnas is very impressive! I recommend the HD 598 to all music fans (s).
