True..I think control is key here as I love my acoustics and phones with less control will add bass to a sound that isn't supposed to be there..Those are the phones that I have issue with..Most cheapo bass heavy iems for example. Now as for the X1 the pads are excellent to begin with so not a real big deal for me. If you want an idea of how they sound you could try out the Fidelio S2 instead which are excellent as well.
Couldn't agree more... Control is key. Why I like the basso. Right amount of fun but still remaining technical. Not the best in any category but has a good balance of fun and technicality to be a great mid tier all a rounder for me.
