I just gave a few away to family, so I'm down to 4 pairs now. I've been using Focal Bathys a lot lately. Best BT headphones I've ever owned. My Beyerdynamic DT 1990 pros have been solid for many years. 

 I like my Sennheiser ones but always interested to know of others. I know of the Beyerdynamic range but Focal Bathys, I’ve not heard of them to be honest. Will look them up.
