Summary:
When I purchased the RS40 two years ago, wireless headphones had not reached the availability that they have now. I am still completely satisfied with my headphones and continue to use them each day.

Strengths:
The wireless ability allows free motion within and out of a room where the base is located.

Summary:
A very nice set of Headphones which sound great. I originally had the model below these which I believe was the HDR30's. I took them back and spent the extra money for a better frequency response and also the convenience of having them recharge whenever they rest in the cradle. I dont have to remove the battery to recharge these.

Strengths:
Good bass response. Portability !!

Weaknesses:
Not crystal clear as with corded headphones. A little bit of noise due to interference that is unnoticeable when playing music.
