Thank you for viewing this item. Unused noise cancellers, set of 2 (Factory Direct). I purchased these about 4 years ago, but they have been stored long-term without ever being used. The packaging has some scratches, dirt, and folds, but the items themselves are in good condition. Since they are unused and have been stored for a long time, I have not checked their operation. I have checked them carefully, but there may be oversights. Basically, returns are not accepted, so please check the images carefully before purchasing. #NoiseCanceller #CarParts #ElectronicComponents #Automobile #AutomotiveParts #AutomotiveElectronicComponents #CarElectronicComponents
