I'm deaf, so I don't have quite the same needs in headphones that most people do. That said, I do sometimes like to listen to music and need isolating headphones (so they don't leak sound and annoy my coworkers) that fit comfortably over a behind the ear hearing aid. Accordingly, I've been using a set of Beyerdynamic DT-770 Pro over-the-ear headphones and I've been really happy with them. I have to adjust them a bit funny to fit over the hearing aid without causing feedback, but they're generally pretty comfortable. They're a bit more expensive at around $175 to $200 depending on where you shop, but might be worth a look.
