I have compared the EX to the VTF3 mk3, I own two of each. The performance is close, but the VTF3 does tackle deep bass better. The VTF3 mk4, with the addition of its Q control, is just going to be that much better. Reportedly there have been some driver enhancements with the mk4 as well. I really like the EX, but if they are the same price, there is no reason not to go with the VTF3.
