  For my purposes, how are the Sennheiser RS 170 and 180 compared to for example the DT770s? I'm buying my first good set of headphones and started to wonder about wireless headphones as I'm a bit unsure how inconvenient or difficult the wires would be in a living room (would they be long enough, would they be in the way etc). 

not much experience with wireless headphones but I think that wired ones are more versatile personally.
