Your first question is what other headsets am I comparing this to. See my reviews of the Motorola HS850, Jabra BT250v, Plantronics 320 Explorer for reference. Now let's consider this headset in terms of the four key performance categories: pairing, sound quality, ease of use, and comfort.Pairing - I was able to pair this headset with my LG VX-9800 on the first try. The instructions in the manual are straightforward so I will not repeat them hear. The experience is similar to what I had with the BT250v.Sound Quality - This is really the top area to question with a headset. I'm happy to report that this headset delivers nicely in this area. I am able to use less than the max volume setting in most cases which is definite progress over the other headsets I have used. On the other end, it is important that you don't have the volume louder than you need it because otherwise people hear an echo of themselves due to the close proximity of the speaker to the microphone. However, I have found the echo to be less of an issue than it is on the HS850.Ease of Use - The key to a Jabra headset is holding the multifunction button down until it flashes. This turns the headset on and off after pairing. You will hear reports of people winding up redialing the last number called when trying to turn the headset off. If you don't wait for the flash, this will happen. I've also heard this reported during pairing, but that shouldn't be the case because you start pairing with the headset turned off. Finally, the volume buttons are easy to use. I only use the headset on my right ear so I can't speak to what it is like when the headset is flipped over and the buttons are on top.Comfort - I also found this headset to be the clear winner in the area over the other three that I have used. I wear glasses so the over the ear hook is a necessity. I think that they have also hit the sweet spot on placement of the speaker. The speaker is raised from the surface of the headset as opposed to the HS850 which is flush with the main body of the headset. However, it does not go into your ear like the BT250v or the Plantronics 320. I guess another way to put it is it rests just outside of the ear canal so the speaker is as close to being inside your ear without actually being so. I think that this maximizes comfort and contributes to the better sound quality. Finally, the vibrate feature is very disturbing if you are not used to it. Don't let that stop you though because it is something that you can turn off if you so desire.
