BIOS Magazine published a review on U.S. Robotics' USB Skype Speakerphone

U.S. Robotics' USB Internet Speakerphone (USR9610) lets you make
Skype calls hands-free. With decent echo cancellation technology, hardware
volume and microphone mute buttons (small blue/red LED indicates the status of the microphone), and full-duplex operation, the USR9610 (28.99) works just like a traditional speakerphone, only without the costs of a long distance call. At the rear of the unit are two connectors for attaching the supplied USB cable and an optional pair of headphones for private conversations.
