Query: Inconvenient Design

I love the concept of this device, however the way they implement it is sloppy. There are no controls on the USB device and you can't plug your headphones directly into it. You must use a relatively large strap as a control device that the headphones plug into. By the time you have it hooked up properly there is more bulk than with other MP3 players with controls on the device.
