That is Rudy Giuliani sporting a pair of Sony MDR-V6 headphone, "V6". One of Sony's most popular headphone debuted in 1984. Complimented by the pro audio version MDR-7506 (has a gold plug and blue label). Arguably very similar otherwise.

"V6" ends the model number of this fine headphone. As does "V6" end Q's trip code. is this something or nothing?
