I had the same idea before I bought my rs180. But I don't think about it now,because as you aware of it, hdr180 is an open headphone. Secondly once I bought it, and see how beautiful it is :P, I don't really want toss around this expensive big headphone. But still I think it will work, in manual it says you can bind mxw1 to the tx180, why not a hdr180 to the tx160? I don't see why sennheiser would limit their kleer technology. Your best bet is call a major sennheiser dealer and ask them to test. Also you can buy the tx160 alone as a spare from that major dealer. Please right back, if it works. Maybe I will do it too, when my hdr180 gets old.
