First of all: the product is already returned! The reason is simple: the sound quality is that of a good, wired headphone, eg Beyerdynamik DT990 as a reference, not compete. The basses are schwammig- "boomy"; the mid u. treble big presence. The sound is diffuse and unnecessarily by several sound stages presets like "Cinema", etc. defined by Sony specifications; not fit properly! Individual adjustment of how to make them by Equalizer, missing. Bring to the handset in the neutral position, ie sound "improvement" of the hearing impression is certainly thin, of HiFi (translated actually "High fidelity") away. Generally, a good headset needs no effect on the sound, which is to reflect "only" faithfully what he type of construction very well may -without aid! Although the technical requirements of Sony (almost lossless, unlike the analog FM transmission) would be given by the digital transmission, Sony has presented them, through the presumably inferior headphones! The product makes a high impression, at least externally, and the operation is clear and simple. The charging station is styled nice; the comfort of the listener pleasant.
