I own 2 RS210 II units. Both cradles are not working. No lights and no recharging of headphones. Possible for both power cords defective?
Hi @gabriele88 , If there is no green light on the cradle then there may be a problem with the adapter or the charger base (or the power outlet) If there is a green light but no red light then this link may be of some help. stopped working no sound no red light
