With these cables, the wires are practically wrestling with each other since I have so many plugged in & I hear no buzz. I called their help number, still optimistic, and there was no one there. Im over the moon with them. La R se ve en rojo abajo/centro/derecha. So if your going to order this I would suggest ordering 2 n doing the same as me. ???? So I remember when these came out. The sound quality is very close to the more expensive pair that I have and the case required a different charger than my more expensive pair, However, my kid cannot tell the difference. Bought these for my step-daughter for virtual school and she loves them! Its definitely the lights he likes the most, but he has a few pairs so I think he might just like the idea of having choices.
