I spent many hours researching the latest and greatest of blue tooth headsets and chose this one based on perceived quality. Price was not a big issue. It is very lightweight which was great. Easy to use as well. The biggest problem was the sound level. You can hear the caller if you are in a quiet place. However, as soon as the level of noise increased in the area you are calling it becomes very difficult to hear. I think the problem is the ear piece. It does not go into the ear, but rather sits on the outside. I have a Plantronics 510 and it worked with my older phone very well. it has an earpiece that goes into the ear and you can set the volume much higher. I only switched because I was getting a lot of static in the headset with the new phone (3G technology may be the issue...I dont know). I would not recommend this headset to anyone working in a potentially noisy environement (driving with the windows open, walking outside, etc)
