Query: Disappointed!

I am disappointed at the headset that I have owned for 4 months.First, the headset does not work anymore. I paired up the bluetooth again, thinking that it was my phone (Blackberry). It turned out to be my speaker on my headset does not work anymore.Secondly, I bought it because I travel extensively and it had some noise cancellation to it. I did not notice this feature on my end of the line nor could my customers, as they could hear road noises.Thirdly, and a very important feature, I could not increase the volume enough to hear when driving!! I am now looking to replace this unit with one that fits IN the ear, rather than on top. My counterparts with this headset also agree, and are looking for new ones that fit in the ear a bit more.My opinion, and I hope you value it, is that you could save some money, and buy one of the other designs that fit in the ear rather than just on top, which should help hearing your conversation when you travel.
