I order these on Dec 22 , and on Feb 15th the right side quit work . I have only ever use these lightly sit at my desk in my office . I try to get assistance from Jlabs but they wont provide support without a serial number , which be on the manual instead of the product . -lrb- why would I keep the manual for a set of earbud ? -rrb- I even do the proper recommend burn in . they sound a bit better than the stock ipod earbud -lrb- but not dramatically so -rrb- , but I do like that they noise cancel do work really well . it be nice to have in my busy office . the fact that I cant get assistance for the way these just give out because of not have keep all of the paperwork seem like a way for the manufacturer to use a loophole and avoid stand behind they product . bottom line : while I like they when they be work properly , they be extremely fragile -lrb- or poorly make -rrb- and the company 's product support be lack .
