Help with over the ear headphones

I’m looking for a set of over the ear headphones for my day to day use and traveling. My Sennheiser Momentum Bluetooth just kicked the bucket on me. I was deciding between the Sennheiser Momentum 2/hd1 or the B&w px. Both have pretty decent reviews but I can’t seem to find many user reviews besides those from Amazon. Was wondering what you guys thought about either of them and if there was anything else you’d suggest?

Before I can really give any opinions, what do you want out of your headphones? Sound signature, size, open/closed, price, wire/wireless, et cetera?
