There are times that I will really have to make calls inside a public place. That cannot be avoided. It's just fine, anyway, but what I really hate when talking over the phone inside a place, such as a mall, is the background noise that hinders you from properly communicating with the person on the other side of the line. While talking, the person on the other side cannot hear you well because hundreds, if not thousands, of people in the background are buzzing. 
It's really irritating since I am not the type of person who likes to shout a lot, so raising my voice on the phone is something that takes too much effort for me. Good luck if the one I am talking to understands me well. So, if it's really an important call, I will have to go somewhere quieter, if I can ever find such a place inside a mall.
That is why I am glad that there are products like the Aliph Jawbone Bluetooth Headset. How does this help me? Well, the Bluetooth headset features a Noise Shield system that eliminates all kinds of background noise during a call while increasing the volume of your voice. This will ensure that calls, especially those very urgent and highly important ones, are better and clearer. And since it is a Bluetooth headset, you could wirelessly make calls within 30 feet (at most) from your mobile phone. The jawbone style also makes the headset non-obstructive.
So the next time you go to some public place, remember to buy the Jawbone Bluetooth Headset. You'll never know when will that mobile phone ring.
