It's Griffin's smallest iTrip yet: a dinky FM transmitter designed to fit the shape of Apple's iPod Nano but is as happy connected to any other dockable iPod.

Like all iTrips past and present, the iTrip Pocket sends out your songs on the FM band. Assuming you can find a clear space - not easy in Britain's crowded airwaves - you can transmit to you car radio or the transistor in the kitchen at a distance of up to 9m (30ft).

The new model adds a neat new touch: a trio of frequency pre-set buttons to allow you to quickly flip between stations should you move into an area where one of them is saturated by a stronger signal.

Available now, the iTrip Pocket retails for $50 (£25/€37).
