I am pondering to upgrade my Sennheiser RS180 to RS195U. I have use 3 so far and latest was RS170 and present RS180 which I have 2 located at different devices.

 

I cant find any review on it so like to know its attributes as regards SQ, Comfort (RS180 is 240 grams while RS195U is 340) , 4/5 hours of wearing, coverage distance as RS180 30 round corner loses connection.

 

I am used to Sennheiser and will it will be sticking to the brand for use in the night will watching TV/DVD etc.
