retiring my Shipsound iphone adapter, any good bluetooth adapters out there?
 

I bought this adapter a few years back from ShipSound.com (great company to deal with btw):
USA SPEC PA11-TOY Toyota Auxiliary Input and iPod Adapter

It's worked great for quite a while now, but the cord is about shot from years of abuse... My question is: is there something better available out there these days, maybe a cordless option? I know there's Bluetooth adapters available now, but I'm concerned about the sound quality. Any thoughts on whether the sound quality is dramatically worse with Bluetooth?

Thanks!
