DT 880s on sale or Something Else?

I am thinking about getting another pair of headphones. I currently own and use Audio Technica M50s. I like my M50s, but I am curious about open back headphones and what they have to offer to the table of audio. I will use the headphones for entertainment such as music, gaming, and maybe some light video editing here and there. I have been researching the Beyerdynamic DT 880s and they sound very appealing to me. I find the DT 880 Pro 250ohm on sale for $170. Should I jump on this? Or is there another open/semi-open pair of headphones that I should maybe consider as well. My budget is around $200.
