Following earlier news from Griffith, Lee Sherman tips us off to additional Bluetooth audio devices at Macworld, but don't get too excited: iPod-only, reduced audio quality versus wired systems (though much better than FM transmitters), and high prices (expect around $150-200+ based on what we've seen from previous products).

Of these companies, TEN appears to have the broadest plans with other stereo equipment promised soon. Ironically, one of the killer apps for wireless connectivity — musical instruments — remains without Bluetooth connections, including the obvious, low-bandwidth choice of MIDI. Stay tuned for the NAMM show next week, though, and maybe we'll see some news.
