The two, one armed with a gun, went into a Radio Shack on Rockaway Avenue Saturday afternoon in the Canarsie section.
Police say they forced the staff into the back room and ordered them to lie on the floor.
The suspects then took Apple and Samsung products and fled the store.
No one was hurt.
Investigators describe the suspects as two black men in their 20's. Anyone with information about the robbery is asked to call the NYPD's Crime Stoppers Hotline at 800-577-TIPS.
