In bass part maybe yes but otherwise don`t agree. Look at X1 frequency graph. To get bass & kick tight with X1 it needs 1) better low-impedance cable 2) amping (FiiO not recommended but will do ok)
Of course they are not dead-flat and neutral but will do ok. Though, for studio purposes there are many better cans.
X1 is something You should use with final music product.
