After being completely disappointed with Motorola HS850 (see my review), got myself a brand new model of Jabra - BT500 and love it. I use is with Motorola V620 (V600 European model). Volume is perfect, sits comfortably on my ear, and does not fall even if I shake my head, people hear me without any problems and distance is good as well. Charges fast and battery last long. Have no problems with echoes or anything else. Buttons are very easy to access and respond right away. I would recommend this one to anyone.
