Had Earpads replaced on 2 pairs of bose. The ear pads are great! And are like new. The 2 negitive things - my wired headphones, the wire plug in the headphone came back loose causing sound to drop out of both headphones. (Does the same with multiple different cables, and it is the same and not the cables) - my noise cancelling ones were having an issue with canceling the noise beforehand, they said there was nothing wrong with them. But there is a difference between my set and a set that does cancel noise properly. It shouldnt amplify small sounds like scratching frabic.
