Pros Crisp/Refined sound
Great with preset EQ or adjusted
Treble is top notch
Minimal distortion at higher volumes
Incredibly comfortable & warm on the ears during winter
look & sound better than the Beats Solos
Mic & play button
Cons The bass isn't overwhelming, whether that's a good thing or not is up to you.
The designs plastic.
Summary If you can live without overpowering bass and want headphones that deliver in other areas then I would recommend getting these, they stack-up well against headphones in the $150-$200 range and are definitely a worth while investment.
If you play around with an EQ player like Radsone then I would recommend buying the HD's, if you use itunes then you won't tell much of a difference compared to the original zoro's (besides the lack of noise isolation & mic/play button on cable)
