It has got 3 mics out of which one is used for the noise cancellation and the other one if used for the Wind cancelation (when are running or when you are driving a two-wheeler). So the voice transferred through these headsets on the other end will be noise free. While you have put on these headsets you will be able to operate it through the voice commands which will announce the caller which call you and if you want to ignore the call then just say the word. Similarly when a call gets disconnected then you can actually inquire from the headsets about the network strength on your smartphone through these headsets. Moreover you can also keep an eye on the battery level with the same voice commands. One of the best features which this phone has is lack of buttons on its body as they mention that the Smart Sensors available on these headsets are smart enough to work as per the intuition of the users. The nano-coating on this device tells us that the these headsets will put themselves away from the wear and tear of the headphones. They will not be working all the time but the moment you connect with your smartphone they will be activated. One of the most popular Bluetooth headsets are Nokia in-ear headsets which are available at the price of 3000 INR I will definitely recommend the users to spend little more and get these headsets as they are much more better than these Nokia headsets in terms of features and technology both. They are available at the price of 5,250 INR and you can order this from the Flipkart.
