I said realistic...did I said it? Yeah the voices of the singers are close to reality. Currently listening to my old CDs---Boy Bands---Westlife, N'Snyc, Boyzone, etc. I never heard this singers sounded like real. Yeah, I think what separate reference headphones like K701 from non-reference is simply--reference headphones sounded real. Not only the voices are realistic, the instruments like guitar, drums, cymbals etc. are also realistic.
I'm a happy headphiler.

The voices of the singers are soulful. It's alive with emotions. Yes, some says K701 is a cold headphone, not warm, but the realistic sound will balance it out. If you love the voices of the singers heard close to its reality, I suggest you pick up any reference headphone---you will be paid for its price. There are a lot of reference headphones out there--it's your choice. Now, I know why is K701 costs around $300 just after 2 years of using this headphones.
Currently, I'm amazed really by the voices---the singers' voice could be husky, thin, thick, soft, hard, etc. You will able to describe it by listening to K701. If you are a singer, I think it's a requirement for you to have a K701 or any reference headphone. You will be able to listen to the lyrics well as the singer deliver it from the first to the last note.

Amazing K701.
Another good update:I inserted the Celine Dion CD. Wow! Smooth-sounding headphone with lots of sparkles. About 10x better from the first day of my K701. Really, after 2 years, this K701 matured already. I can't imagine how many times will it be better if I have already reference amp and reference source. I am just using a cheap Fiio E9 + Philips VCD Player!

I can say now that with around $100 for an amp and maybe also around $100 for a source, you can experience "
initially" what is meant by a reference sounding headphone.
