All you need is a pair of ear buds and a smartphone. Then you can change the way your ear’s listen surrounding voices. These wireless ear buds fits in your ear and then it will change the nature sound.
And here it is how it works, these ear buds connect to the smartphone and an in build app holds the key for functioning of the ear buds. App provides you with different options like equalizer , volume ( Here volume doesn’t mean just an option, where you will increase OR decrease. But this is a different option where you will be able to see it in decibels and also noise cancellation included by default). Sound effects, Filter modes.
If you think this options are just like the which your smartphone currently persist, then you are wrong. Here Sound effects means you can add a Baby voice or your friend’s voice. Just assume when you went to a concert and they play a slow & melody music, but your interest is in Rock music. Then just change the sound effect’s like bass and other effect’s, then you can listen the same Live song in Rock.
Now with this New Gadget remove the Noise from your life and fill it will pleasant Music……….
