1MORE Dual Driver In-ears @ TechPowerUp
 

1MORE's Dual Driver is the new younger brother to the critically acclaimed Triple Driver In-ears. It inherits the exterior design of the Triple Driver, which is great as it has proven both durable and comfortable. However, on the Inside, the Dual Driver is completely new, featuring one large dynamic driver with graphene coating and one balanced armature tweeter.
