OCIA.net has posted their review of the Logitech G35 Gaming Headphones
Each earmuff has an adjustable slider that ranges from 1-9. It makes a nice, satisfying click each time you change to a different number which I found handy with trying to make them even without taking them off your head. The earmuffs also swivel from side to side.Logitech G35 Gaming Headphones Review
