Right ear in Sennheiser 461G is completely silent. Help?
Tripped over the wire of my Sennheiser 461G over-ear headphones (it only goes in to the left ear and is connected through the headband) rushing out of the house and when I got back only the left ear plays audio. I was really in love with these headphones and since they just went out of manufacturing the price to replace is high.
