He asked me to compare the V6 to the DT880's............
The V6 is used professionally for MONITORING work, not for mixing, mastering, effects, or any critical listening other than live monitoring.
The 880 is not marketed as a studio headphone but it does a better job of it than the V6 and when comparing the two to each other the V6 might as well not have any highs at all next to the 880's soaring clean sound.
Take a look at their frequency response and my observation holds up graphically. The V6 loses up to -25 db from 10khz to 20khz compared to the 880.
In practice I didn't find the V6 to sound nearly as veiled in the highs as the graph suggests, but compared to the DT880's highs, like I said its like throwing a 90lb weaking into the ring with a heavyweight boxer.
Also, can you site your source as to their professional use?
