RS 220 worth? or RS180

[SacredChili]

So, let me start off by saying that I currently have a Beyerdynamic dt 880 premium headphones + Fiio E10 combo. I LOVE the sound, its remarkable, clear, and very rich in all the right aspects without being to boomy. But, I honest to god hate wires, and it has gotten to the point where I am replacing them to get a wireless headphone. If I am going to go wireless I am gonna get a high quality brand like sennheiser to try and imitate the sound that I currently have. I am pretty much purging all the wires in my home office that I can do without and managing them to make my office look like a clean spacious/managed environment. My question is, are the RS 220 justified in the extra 100$ on Amazon? I cannot live without cloth so these are the only options wireless can offer me in this department. I plan to just buy a modmic whenever I want to VOIP with friends and play games etc. This is for PC mainly also. Thanks!
