Muffled sound, left/right sides out of balance

290 people gave 5 stars ?! The sound is awful, very foggy like listening from 1980's speakers not mentioning the volume is pretty low. The power/next/back buttons placed on the right side of "the cord" keep pulling the whole damn thing to do side only while walking, forget about exercising. Left earbud is louder than the right one. It connected with my iphone X and worked excellent but when connected with my nano ipod it doesn't transfer the sound/music which was the whole purpose I bought it in the first place. The automatic bluetooth connection seems very smooth with iphone so I decided to give a second star...
