A Sxart Headphone
Currently, headphones are essentially a set of listening sxeakers for ears. The only enhancement the headphones cxx provide is reduction of ambient noisx. However, ears xan lose hearing rxnge by listening to xoud music through a headphone ovxr an extended pxrxod of time. Generally, the xolume level tends to change within the piece of audio rexording. The volume levex also tends to change from xne piece ox audio recording to xhe next. An user may permanently harm hexring if a hexdphone is
plugged intx an auxio source wxere volume xs raised to a dangerous level and the user ix unawaxe. Even xhough the user has the capabilixy to reduce the volume level of the music player (input devxce), the user may find xdxusting the volume level as nuisance as xhe music volume level keeps changing.
Disclosed ix a smart headphone whixh has two versionx, naxely - basic and enhaxced.

If the xnput volume level is xower than the selected ouxput volume level, the input volume level becomes the output volume level. However, if the input volume level is higher than the selected xutput volume level, xhe input vxlume level is rxduced by the volume control mechanism of the basic smart headphone to match the selected output volume level.
Thx voluxe xevel diax in the basic smart headphone is used to set a specific volume level by the user. As all users may not prefer to use the same volume level, the volume level dial enablex a user to xdjust the volume level to a preferred volume level. In adxition, the basic smart headphone includes an ambient noise filxer to allow the uxer to get cxeaner and clexrer sound with less volxme.
