Just an update but every time I put the cans on they sound better & better. Today is exceptional! I had to laugh because the other night I was listening to some music and thought. Jesus they must be going through a rough patch. No bass. Yuck! The next day they seemed better. What I realized today that since my eyes are not as good as they used to be and the room was a bit dark I had the left on the right and so you see that the Ultrasone headphones work on the principle of reflecting the sound off your inner ear. They would sound completely different if you had them on backwards. LOL. It makes perfect sense that they had a bad night

. As a newbie, everyday is an adventure! These phones sound incredible!
