         5 . The hair drying device of  claim 1 , wherein the electric motor is a brushed DC motor. 
     
     
         6 . The hair drying device of  claim 1 , wherein the electric motor is capable of rotating the first fan and the second fan via a magnetic gear. 
     
     
         7 . The hair drying device of  claim 6 , wherein the magnetic gear comprises a right-angle drive. 
     
     
         8 . (canceled) 
     
     
         9 . The hair drying device of  claim 1 , wherein the handle comprises the sound dampening material. 
     
     
         10 . The hair drying device of  claim 1 , further comprising a cooling mechanism configured to cool the electric motor. 
     
     
         11 . The hair drying device of  claim 1 , wherein the first fan and the second fan are each configured to operate at below about 15,000 RPM. 
     
     
         12 . The hair drying device of  claim 1 , wherein the hair drying device comprises a computing device configured to control a plurality of hair drying parameters. 
     
     
         13 . The hair drying device of  claim 12 , wherein the hair drying device comprises a display communicatively connected to the computing device configured to present the plurality of hair drying parameters. 
     
     
         14 . A hair drying device, comprising:
 a housing comprising an inlet, an outlet, and a handle, wherein the housing is configured to house:
 an electric motor at least partially encased within a shroud; and; 
 a plurality of fans comprising a first fan and a second fan electrically connected to the electric motor, wherein each fan of the plurality of fans are configured to rotate in a bidirectional manner; 
 a heating element; and 
 a battery configured to provide electrical power the electric motor and the heating element; and 
   a display device located on the exterior of the housing, wherein the display device is configured to provide one or more alerts to a user related to a power level of the battery.   
     
     
         15 . The hair drying device of  claim 14 , wherein the heating element comprises one or more fins. 
     
     
         16 . The hair drying device of  claim 15 , wherein a length of the one or more fins extends parallel to the central axis of the housing. 
     
     
         17 . The hair drying device of  claim 14 , wherein the electric motor is a brushed DC motor. 
     
     
         18 . The hair drying device of  claim 14 , wherein the electric motor is capable of rotating the first fan and the second fan via one or more magnetic gears. 
     
     
         19 . (canceled) 
     
     
         20 . The hair drying device of  claim 14 , wherein the first fan and the second fan are each configured to operate at below about 15,000 RPM.
