Sennheiser  RS-65 Wireless RF Circumaural Headphones with SRS Surround Sound Processor (Black)
Bad receiption, can't move your head, high pitch noises
I read the review, still thought to give a try as it was cheap. However after using it I returned it in a week. Amazon was good to take back the product without the shipping charge.  <br /> <br />This product gives lots of noise, it will be worse if you move your head even one inch. Sometime those noise are high pitch noise, which really annoy someone, who want to concentrate for work, while avoiding outside noise. <br /> <br />I actually took this product for my work place, where I want to do coding without outside disturbance by putting some slow instrumental song. It didn't work out, I was sitting only 3-4 feet away from the transmitter, I even tried retuning many many times.  <br /> <br />They have given one extra battery for headphone, that sits in the base station, behind the antenna.
