Volume and mute fuctions on cord. My Sony headphones are model #MDR-RF985R and they do fit this model. And i normally use one at a time. Right now a full remodel of a small bathroom. Personally speaking I would prefer it didn?t have the hook on the side for a lanyard. Nice sound, and all is good. Audio is better for me with a wired than with bluethoot. not true to size El color tal cual la pagina, lo pedi medio numero mas por el precio y me quedo bien, el modelo es para empeine alto, puesto se ve un poco tosco, pero de buena calidad, la plantilla trae memory foam que lo hace muy muy comodo Color is sort of more mustard than I thought it would be.
