Got my open-box Atlas today too. I have Andromedas and Comets currently. I love the Andromedas and got the Comets for my commute / use with phone whereas Andromedas are for use with my AK SP1000m or Mojo. I never missed bass with the Andromedas but the Atlas is a whole different world. I've got a few hours on them so far and really liking them with hip-hop. I've only used the medium foam tips so far -- I use SpinFits on the Andromedas and Finals on the Comets.
