Range was as good as any similar style earbuds without dropping out over a room away. Got half a size bigger and fit perfectly (usually have size 8. However, warning, it is ridiculouslyyyyyy hard to hang up. ) or replace them. However, the pair sent to me seemed slightly worn already. She did complain about the rubbery material picking up fuzz and lint. however the more power you throw at it the better it sounds. A good buy and a good price! No pongo 5 estrellas por que creo que falta informacion para configurarla con algunos dispositivos; con una tv lg nunca funcionó por el puero hdmi que indicaba el manualmde bose pero con samsung sin ningun problema. I mean this in the best possible way.
