This is the second time that the headphones have a problem where one headphone starts to sound worse than the other. The cable is in perfect condition, the connection is normal, the problem is inside. The headphones have not been used outdoors and have not been exposed to water. The photo shows $2,000 headphones, Dan Clark E3, after a year of use. As soon as loud music is played, contact is temporarily restored. The first time Dan Clark Aeon worked for a couple of months and was returned to the store after several attempts at repair by the store that led to nothing.
