Title: Buyer beware...
Review: These are a waste of you're time. These headphones are by far the worst product that I've had the misfortune of procuring. They cut out during the first few minutes of operation, then stopped working completely. Nice. Without equal, the worst product i've ever purchased from Sennheiser. Most like it will be the last.
