I have not seen nor heard of any B&O bluetooth speakers. I was for years a fan of their higher end turntables and phono cartridges; I'm showing my age, I guess. Will have to see if they have something out there. Otherwise, the Logitech is probably a good way to go. I once had a Logitech dock with the 30-pin connector that, for its sound quality, was qiute a good deal.
