I have the 100ABN and i'm happy with the bass. I tried the WH-1000XM2 and wasn't happy with the bass. Are the sound and bass in the h.ear on 2/H900N similar to H.ear on/100ABN (their predecessor)? Just to give you an indication, I have the following headphones and I'm happy with their sound: Fostex TH-X00, Sony MDR-1A, Sony 100ABN. I mostly listen to pop, hip hop, R&B, rap, EDM, house etc.
