Yeah they have that valley of trap as well, but actually they are not that crap, they have good technicalities as great layering and imaging despite smooth trebles. It is one of the cheapest EST you can try, and have ok EST implementation on treble extension, but they lack of bite because of the valley of trap. They should boost 6khz properly and the dip is too much also. THe bass raise also good, but driver capability is just OK for me, thus lead the bass isn't great of midfi class. They need decent source to be shine, and pair it with pure silver cable does the job right to make it more sparkling and and bitey. I still can't recommended it per se, they are just what they are on their price. But if someone want to hear EST on budget, the mofasest trio is one of the cheapest that you can grab, and only you like smooth presentation.
