returned a pair of beats fit pro TWICE

today i went to walmart & bought the black beats fit pro & when i charged it up only the right ear worked. i went back & replaced it for the white ones & now they won’t connect at all. am i doing something ? or are beats overall not a good quality product for earbuds…. or is it bc i went to walmart ? i saw a lot of good reviews on here so lmk where y’all got yours
