  1. Los auriculares se me han desemparejado, ahora aparecen los dos por separado cuando busco dispositivos por bluethooth. Necesito saber si hay forma de emparejarlos de nuevo, Gracias.

    1. Me paso lo mismo y lo solucione pulsando los botones de los auriculares 5 veces seguidas para reiniciarlos, los volví a meter en la caja, los saque y ya no salían por separado dos dispositivos bluetooth en el movil

  2. Volume dropped first in an earbud then in the second, and now is hardly audible, seems like internally lowered the volume but I see no way to rise it again:

        1. i had the same problem.
          you try. unpair from any device. close the headset and open. again. without to conect to a device pres the headset button until you hear pairing. then connect again with bluethout. it will work
