I've owned several pairs of neck-worn earbuds. I'm convinced that this style (versus the individual earbuds) are the best. Although the sound quality of these is fine, I get complaints from people that I'm on the phone with that they can't hear me well.

They work all the time, which is saying a lot for Bluetooth headphones. A little awkward with the wires but still okay.
