It was before i started looking properly into headphones, i was ignorant and thought Sennheiser + high price = good, wanted something wireless and went for those, biggest mistake ever, was about 2 years ago now.
If someone made a wireless planar with absolutely zero interference or hissing i *might* consider it, but it's unlikely given how power hungry they are.
Senn. does make some great corded...
Sounds like you didn't research in great depth at the time, there were solutions 2yrs ago.
Re wireless, try out the newest ones on the market that use kleer or apt-x (less impressive).
May be better options now, haven't looked closely for 18mth+.
There's been "big" improvements in the 4yr+ (?) since the RS140's.
