Question is, what kind of music you listen?
There are headphones with sound signature generally suitable for rock, (Grado products. Fun and tight, but brightness might turn some people away)
headphones with sound signature generally suitable for classical. (Smooth and soothing. Most Sennheisers and some Beyerdynamics)
And there are headphones that have no coloring to direction or other whatsoever so they are basically suitable for everything (and play music with sound it is recorded) but might be boring with their analytic attidute. (Generally AKG and some Beyerdynamic)
Then there are Bass heavy products for bassy music. (Another head of fun-sound. Some Koss, some AKG, some Beyerdynamics, some Sennheisers)
Alessandro's are modified Grado products. They have bright Rock signature of Grados, but are more balanced so they are suitable for practically everything without being boring when you want to rock your socks off. Soundstage is very small though, just like Grados.
Again, what music you generally listen to?
