Transmission range is more than adequate. You can also switch the room and close the door. If necessary to get in a different floor, but it comes at movements then dropouts.
The comfort is very good. Unfortunately, the buttons for the volume and balance on the right earpiece can be distinguished only with difficulty by feel. But with a little sensitivity and familiarity that goes well.
The sound is at rock / pop but also excellent instrumental and vocal. The sound volume is full, without being intrusive. Vocals are clear and natural. As long as a signal is coming, no noise is heard. Only in gaps between tracks occurs a very quiet clocked noise.
The RS 180 is a total of a clear recommendation.
