The first BT8010 had very bad microphone pickup quality. (people who I spoke to on the phone could not understand me), had no volume, and the sound quality of the Blue Tooth Stereo speakers was worse than an AM Radio station. So, I sent it back to Jabra for an exchange. The replacement had much better microphone sound pickup quality but the Stereo Headset sound was again, no good at all. I have a Nokia 6265i.I also paired it with a Motorolla Razor phone and heard no music at all.Unfortunately, the earpiece is very awkward to put on, because the plastic "over the ear piece" keeps falling out or is hard to get into position. Once I had it on, the circumference of the ear bud that fits into the ear is so large that it causes pain if wearing it for more than 10 minutes. It is great for people with extra large ears though.To summarize, I am very dissapointed with this particular headset but I am eager to try another kind if they make one that has good, strong stereo sound, is easy to put on, and does not hurt the ears.
