this product be just terrible . they be confuse to set up and once you set they up they hardly work . I have spend copious amount of time look for good headphone and when I get these i have hope this would have be my lucky break , it be not . they have terrible connection , and they do not hug the ear . the constant static noise be unbearable . I think i have spend more time try to tune they than I have be use they . I wish that these headphone be wire there be actually more wire and less freedom involve with this than wire headphone . let I get to the pro and con pro : comfortable Wireless Battery life con : constant static noise more wire involve do not hug the ear hard to set up short range Ambiguous and even incomprehensible instruction battery must be replace tune it be a hassle the major problem be that even if you get the perfect tune there be still a static noise in the backaround
