The Bottom Line: The Griffin iTrip Universal isn't ideal as an in-car transmitter, but its USB power and small size make it well-suited for use around the home.
The Bottom Line: The Griffin iTrip Pocket wins points for its supersmall and stylish design, but its weak FM transmission can't hold water in urban areas.
The Bottom Line: If you want to bulk up the sound of your PSP without running cables to your stereo or a set of powered speakers, Griffin's iTrip for PSP is a nice--though slightly pricey--solution.
Editors' Take: Like a lot of other FM transmitters, the Griffin iTrip sometimes suffers from noticeable interference but operates beautifully overall.
