the audio quality of the ne 700 's be superior to every other set I have listen to ; dynamic range , image quality , sound isolation ... it be just a shame they keep break . the people at NuForce get a `` a '' for effort and ungrudging send 3 set of replacement before `` promising '' a full refund -lrb- still wait for the refund , its only be a couple of week so I be not worried yet -rrb- . each set have the same failure , death of a channel -lrb- usually the right -rrb- . unfortunately the failure can not be attribute to abuse , I have a cheap set of Jabra 's that I wear while do any type of physical activity that I have own for year . the ne 700 's be reserve for list around the house , air travel -lrb- which be where I appreciate they the most due to the great noise isolation -rrb- or while I be sit work on the computer . I would have give NuForce one star have it not be for the exceptional customer support effort and the audio quality but I would not recommend purchase this product until the durability issue be address . read through other review , my problem be not a anomaly . I hope anyone else that buy this product have better luck than I .
