sorry I was at work so couldnt get into much detail.
dt1350 is much more transparent than 1r, and has much higher resolution which leads to a more vivid sound. In these two regards 1r is below average. Some people may like it for rock and hip/hop, but to my ears its sound is muffled and veiled.
The problem of dt1350 is more inherent with most beyer phones which being having a rough treble texture and thin bass. It could sound atrociously horrible with some female vocals.
For the price of 1R, I would look at esw9 or es10.
