會考收音機耳筒一問

請問會考收音機耳筒係唔係一定要用放耳仔入面個d呀..得係細細個個塞住耳仔個d
例如http://hk.search.yahoo.com/search/images?view=detailed&p=%E8%80%B3%E7%AD%92&b=65&pstart=1&curr_index=7&imgsz=&imgc=&ei=UTF-8
定係咩耳筒都得..
我問下大耳筒個d得唔得...得係唔得..得係唔使塞住耳仔..有條野連住兩個耳筒例如http://hk.search.yahoo.com/search/images?view=detailed&p=%E8%80%B3%E7%AD%92&b=9&pstart=1&curr_index=1&imgsz=&imgc=&ei=UTF-8
