What is the difference between these hifiman sundaras?

I’m looking at getting some new headphones. I have hifiman he560 v1, but the left driver cuts in and out intermittently. I see two listings for sundaras both sold from the hifiman store. One is $179 and the other is $292. They look identical. Maybe different versions? Which should I spring for?

Any other recommendations for open back headphones around the same price point? I’ve looked at the hd6xx also, but from what I’ve read they aren’t as “warm” or bassy as the sundaras. I like more bass than your average hifi listener but still want nice clear audio all around. Thanks in advance!
