A good BT antenna can get to 50+ meters in open air. (Source: Saw it happen during testing.) Best case scenario and all that. :) For something that is designed for a personal area network, the range suffices. The problem comes in with poorly designed products, cheap antenna designs, or just space limitations. BT Earbuds don't exactly have a lot of space in them.
