Griffin Technology has finally released an update for their iTrip transmitter that works with iTunes. Until now you had to use MusicMatch to get an iTrip to work, and it was a pain because — although it is a great player — MusicMatch bites it when it comes to synching your iPod.
BTW…just got my Shure E2C earphones for my iPod. Takes a bit of getting used to the feeling of waering them but the sound quality is great. You really ought to try them.
