Tested the S7 Edge here in singapore with the W60. First thing i noticed was a higher quantity of sub-bass than my s6 edge and xperia z3 compact. IMO the Mids are kind of thin sounding and Highs are less detailed when compared to my Z3 compact. I compared all 3 devices while listening to taylor swift's fearless flac. The most noticeable thing to me was with the snare drums, the xperia z3 compact had more detail and air while the s7 edge sounded rushed and artificial. But preferred the S7 edge when it came to the bass which is definitely a step up from my s6 edge and Z3 compact. That said, i think that the sound is an improvement over the s6 edge
