A 2nd headphone is useful for enjoying the Sony MDR-DS7500. It works well. Thaanks to he notice delivered on the web site, it is esasy to connect the headphone to the base. Unfortunately, no MDR-DS7500 AC Adapter is provided. Two headphones for the same adapter is not sufficient. An additional MDR-DS7500 AC Adapter would be useful.
