I used other models of wireless headphones, mainly Sony ones, but they all had issues with interference and unwanted white noise whenever I moved my head. With the RS 180, I have yet to hear any noise, even when I go to the other side of the apartment to get a drink. The sound is clear and precise, the headset isn't too heavy.
The controls take a few times to get used to, with the On/Off button being between Sound up and Sound down, weirdly enough, but I never got it wrong, so maybe it isn't that weird!
Battery life is FANTASTIC! I ran it for 18 hours straight once for a Breaking Bad marathon, it kept going, then I charged it for 6 hours while I slept and was able to get another 12 hours, without any sign of battery fatigue, so I have no idea when it would have shut down, but I certainly would have before them!
I have quite a big head and had no issue fitting it. I have to say, it feels a bit weird on my ears, because all the sides are touching them (the headphones go over the ears). It's not painful in any way, but a bit bizarre feeling.
It feels a lot less hot, being velour-covered, than leather ones, at least.
I'm very happy I treated myself to these headphones.
