Well I just bought the Target Just Wireless Adapter and it works fine. It may be mono sound, (I dont know) but it sounds good to me. I guess they only way for me to tell the difference is if I hear the sound on one of the true stereo adapters, with the three rings, instead of two, till then I'm pleased. $14 with the retractable cord and mic with no shipping cost, hey I'm happy. Guess I'm not hard to please.
I'm using the JBud headphones, bought on Amazon for $20. So with my case, headphones and adapter, I think I'm done spending money on my BB.
