I ordered this set of Sennheiser RS120 Wireless headphones to use in my new addition sun room. I tried them out when they came in just to see if they did, in fact, work. They did, but with some minor background hissing and popping noise.Just now when into my new sun room to watch a movie so not to disturb my wife. Nothing BUT hissing and popping sounds came from this headset!! So I used them for about 1 hour when they first arrived and for the second time I've had them on my head, NOTHING!! And yes, I did try to tune them by changing the setting on both the base and earphone, without any success!!The return window expired in October!!That'll learn me!! Maybe they'll make a good paper weight?? Sure not good for anything else!!Just get some long wires and plug in the 'Skull-Candies'!! ALOT cheaper, too!!Did I mention that these set on top of (outside)your ears and won't stay on your head if you look down??? Not well designed at all.
