I used to have Sony MDR-DS3000 but I could not stand the hiss! I bought these headphones after some claimed that there are no background hisses. Unfortunately there are slight hiss in the background when watching TV programming with mostly dialogues. otherwishe the hiss is unnoticeable. I love how the RF transmission allows me to walk around the house while listening to tv unlike the Infrared ones like Sony where you are limited to 90 degree angle in front of the base unit. The connectivity is very good with two toslink inputs, one RCA input, and one toslink output. I have my PS3, cable box, and the dvd player hooked up and its very convenient. I'm not much of audiophile, but as far as I ( an average joe who wants a surround sound for gaming/movies and doesn't want to wake up the neighbor in process) these headphones have great sound. I highly recommend it over any other wireless headphones with surround sound decoder.
Pros: CRYSTAL clear and jitter-free audio signal via highly-stable infrared link. Superb sound resolution throughout audible frequency range. Decodes Dolby Digital and DTS! Comfortable on head, you'll forget it's there. Headphones run off standard AA batteries (no risk of having to buy a proprietary company-supplied battery that is expensive to replace, and not guaranteed to be produced in the future). Headphones are sleek and stylish, and so is the base unit.
Cons: Limited line-of-sight range (inherent with IR signals); limited to about 30 ft. and must be free of obstacles in the Rcv path. Plastic construction of the headphones are a little brittle and not meant to be mistreated. Base station produces a generous amount of heat right near the input AC power receptacle. When starting audio, there is a half-second delay as the base unit synchronizes with the audio stream (minor nuissance, and this might only be a problem with digital audio signals).
