Input:
They are just the standard to which other headphones should live up to. Sadly, they beat out my $300 Shure in-ears in ease of use and a wider range of sound and I wish I bought these first. I recommended these to two different friends and both rave on this model. One of which returned his $300+ "Beats" ear cans in lust over the MDR-V6.

-Excellent response and tone.
-Great at high levels of volume without becoming unpleasant.
-A best-buy for the sub-$100 price!
-I don't imagine a better headphone for under $400 compared to these, outside of Grado Labs line of open-air design headphones for open sound quality)
