i have not get mine yet , but i have be look for a way to listen to my 42 '' hdtv , that only have digital optical audio output , for some time , to just get a decoder that do not have 5.1 capability will run $ 30 or so , and a decoder that have 5.1 capability will run $ 100 more ??? and so that only leave headphone that come with a decoder , and after read up on what available , it be not look to promising , only if you want to go top end , $ 200 + even the one around $ 150 have not get better review than this one , the hissing noise and wireless interfearenc ? and some of those decoder will not do 5.1 ?? but for $ 20 wonderful dollar you can get that $ 130 5.1 decoder !!!! just use different headphone , and like i read in another review , that take care of any crappy sound , not too many decent and affordable option for the digital optical audio only output for the new hdtv 's , that still let you use you 5.1 sound ?? glad i do not opt out for the astro a40 , or tritton ax pro , which be not true 5.1 , or turtle beach x41 , those be mostly for game console , and a little pricey , so these should do nice for just t.v. useage ,
