 I am looking to add another pair of headphones to my collection. Coming from Akg/Sennheiser what other headphones can people recommend. I was thinking Beyerdynamic dt 880 or something like that. I like open headphones only, and prefer clean neutral sound. I currently own a pair of AKG Q701 and love them. Also, i have owned a pair of HD600 in the past and really enjoyed them. So any recommendations would be greatly appreciated.
 
My current set up is Magni/Modi
 
Budget $200.00 maybe could go $225.00 
 
Thanks
