Xboxic points X360F to this Amazon UK listing for the much vaunted Datel Bluetooth
headset. Amazon currently has the item available for pre-order, with a release date of June 30th. I'd take this release with a grain of salt though: the original date from Datel was March 17th. Datel's awful website still makes no mention of the product at all.
Of course, let's not forget that it's still awfully pricey at about $105 US for the adapter/headset package. Hopefully, Datel will get a clue and realize that some people already have a headset and just need the Bluetooth adapter.
I mean, it's not like people have been making adapters themselves...
