Wireless Upgrade from RS 120II ?

[Flappy]

I would appreciate some direction from the headphone gurus please!I  feel its time to do an upgrade on my trusty Sennheiser RS120's...I really enjoy the freedom of cordless and plan to stick with wireless! I'm thinking of the RS175 or 185 anyone with experience on these 2 and if the higher price on the 185 seems justified,any difference in sound or comfort?.....also is there anything else in this price range that I should be looking at? Thanks
