I work the night shift on the floor of a manufacturing facility where I be surround by modern machinery , electric panel , computer , a wi-fi network , row of fluorescent lighting and concrete block wall , so I be hesitant to try a wireless headset . my main listen interest be sport talk , ballgame , news program , and talk show . the headphone be hook into my satellite radio boom-box via the headphone jack -lrb- with the volume on the boom-box turn up all the way -rrb- . well let I tell you , I receive great reception and quality at 90 yard -lrb- and that be with about 50 machine between myself and the transmitter -rrb- . only the slightest crackling and minor hiss can be hear at that distance . be about 60 yard away from the transmitter with a concrete block wall and 30 machine between , the audio be sufficient enough with some crackling , hissing and breakup . while in my main work area -lrb- about 2000 sq. ft -rrb- and in direct line of the transmitter , the audio be spot on with absolutely no crackling , no hiss and no interference . I can not `` accurately '' comment on the music quality b\/c I do not have `` a ear '' for it , but it be as good as any ` wire ' headset or ear bud that I have own . the placement of the dial do not present a problem for I . I have no difficulty adjust the volume , tuner or on-off switch , even with work glove on . these headphone be worn daily for a minimum of 8 hr . a day , and do not lose a charge . you can tell when the battery be die when the audio quality start to diminish . they be plenty comfortable -lrb- even w \/ safety glass on -rrb- with ample padding . my only complaint -lrb- and it may be genuine to I -rrb- be the fit . I have a good size melon -lrb- 7 5\/8 -rrb- and these seem to wiggle a bit while I be work . I do some lifting and reach at work and while do so , I sometimes have to try to keep my head level so the headphone do not slide down or back . again , this may be unique to I as I may have stretch these beyond they capacity . = -rrb- I highly recommend these headphone and would have give they a 5-star review have I just use they in a `` idle '' position .
