This is my first bluetooth headset which I decided to purchase because it is actually two products in one; a mono bluetooth headset that converts into a stereo headset. However I have been very dissapointed in this product. Call quality is terrible and the connection is downright unreliable. I attempted to do a firmware upgrade on my first headset and it would no longer work after that and had to be exchanged. Jabra customer service was a complete waste of time. After receiving my second BT8010, I wish I had just returned it for a different product all together. The caller ID doesn't work; it switches to music mode even when you don't won't it too and it is very bulky and uncomfortable. I unfortunately have heard that it takes several tries to find the right fit with bluetooth headsets. I will keep trying.
