the DualShock 4 Back Button Attachment.The device adds two new buttons to the controller by clipping onto the rear of the DualShock 4, plugging into the jack traditionally used for headphones.These buttons can be assigned to replicate the function of any other button on the controller. So, for example, if you’d rather tap the harder-to-reach Triangle with your grip fingers rather than your thumb, then you can assign triangle to one of the back buttons.
This means the Back Button Attachment works akin to the paddles on the back of the Xbox One Elite Controller, or the variety of third-party ‘pro’ controllers from companies such as Scuf.
Between the two buttons themselves is an OLED screen that provides real-time information about the commands the buttons are currently programmed to.

Sony explains on the PlayStation Blog that the buttons can be reassigned on the fly using a dedicated remap button.
The device will be available in the US and Canada on January 23, and in Europe on February 14, retailing at $29.99 US / $39.99 CAD / €29.99.
