foreword : I use these for my home computer . I be 23 and a very experienced computer user . there be a few thing about these headphone that make they seem as if they be design by someone who have never be tell what they would be use for . let 's start off with the fact that they be wireless headphone , but the charge base have two frustratingly short wire you need to accommodate . there be the obvious input jack that pull the sound from the computer . it be so short -lrb- 4 or 5 foot maybe ? -rrb- that it become a real pain to position in a convenient\/attractive way in the room . it create one of those taut , easy to accidentally snag hang wire situation that have end in my charge base startlingly slam to the floor on a few occasion . the charge base need to be plug into a wall jack with a equally short cord , however , this one end in a inexplicably large ac adapter that will require you to shuffle -lrb- if not completely unplug -rrb- some of you other gadget ac input . yes , you have hear I right . amount of wire to deal with on a regular , 2 dollar set of headphone from a 7-11 : 1 wire . amount of wire to deal with on a pair of 70 dollar sennheiser : 2 wire , both of which be too short and clunky . be I miss something here ? perhaps even worse be the auto-off feature of the headphone . if the headphone receive no audio information for about five minute -lrb- i.e. the CD you be listen to end , the movie you be watch be over and you have fall asleep in bed -rrb- , the headphone will shut off to preserve battery life . but rather than just go quiet , you get a earful of unending , louder than holy hell static . so every time you pc go quiet for more than five minute and you have those headphone on , get ready to crap yourself when they kick in with horror-movie-level , ear-splitting static . I know these have get great review , but most of those come from people who have own the product for about a week . over prolonged use , you learn to hate these thing . do yourself a favor and buy a cheapo , 1-wire , no static pair from anywhere else .
