Narrative:

I was being vectored for downwind to 27L (atl) heading 090. Captain was late calling 'in range' to company and was on another frequency. (Although company provides headsets, captain preferred not to wear.) I was having trouble hearing the controller with both company and ATC on speakers. I apparently heard a similar call sign's directive to turn on a base leg north. The controller vectored me back around to downwind with a left turn. I continued and landed without further events. (ATC commented that we had mistakenly picked up on a turn for other traffic.)
