Review: Headphones work great - A really great set of headphones. Very durable and long-lasting. Have owned for 9 months and still have not broken. And they are exclusively worn by 6-year-old. Sound is nice and clear. They connect well to any device. The price for the unit is decent given the longevity of the unit itself.
