I had this headset for about 5 months, I mean I had 3 of them. All of them had one same problem - super low volume. And it cannot be increased. First one I got I thought it was broken, but when got the replacement, same problem with volume... Two months down the road of very low usage, the main button went bad. Anytime I wanted to start using it, it would redial the same exact number, no matter which number I dialed last. I sent for replacement, got my third one and had same problem with volume. Decided to sell it on eBay. Got myself a brand new model of Jabra - BT500 and love it. Volume is perfect, sits comfortably on my ear, 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.
