Great all around product! Seem very durable and are super comfortable! Yeah, the DT 990 are no slouches, but they dont transmit the emotion that the DT 880 do. It is so silky and comfortable to wear. They have a comfortable, fully customizable velcro closure that allows for someone with a sensitive foot to adjust as needed. Go grab one. If you get these furry "flip-flop slippers," make sure to tell your child not to run in them. I have tried all the different sizes of buds you can put on them and these just keep falling out of my ears. And they are surprisingly spacious! They promptly sent another.
