We have an iTrip for every iPod – including the iPod U2 Special Edition iPods. Click the [ Buy Now ] button to pre-order yours now. Shipping in November.
The coolest iPod accessory in the world is now available for the coolest iPod in the world – the jet black iPod U2 Special Edition. The iTrip FM transmitter for the iPod can play your music through any FM radio – in your car, at a party – anywhere the mood strikes you and there’s a radio.
iTrip is made specifically for the iPod. This gives iTrip advantages over similar devices. For example, with the iTrip, you can have the cleanest possible signal, because you can choose any radio station on the FM dial to tune for the best performance. You do this by ‘playing’ special station codes directly from the iPod itself. Simple.
Another advantage of the iTrip is that it needs no batteries – it receives its tiny amount of power from the iPod. No more batteries ever again. There’s not even a power switch – just plug it in and go. It shuts off automatically after 60 seconds of silence, just like the iPod.
The iTrip is the ultimate accessory for the iPod because it allows you to share the music and share the fun beyond your headphones. Don’t leave home without it.
