DNA by monster or sol republic tracks v8
Neither. My money would go to sennheiser Amperior or sennheiser hd25-II or V-Moda M80. If you are so keen on spending money on overrated/highly marketed product like the ones you mentioned, then go with soul Republic. They are slightly better than monster.
Sol republics are orrery nice for the money. Don't ever buy a monster product.
