A mobile device having first and second opposing sides comprising: a processor; a first speaker positioned at the first side; a second speaker positioned at the second side; a first microphone positioned at the first side; a second microphone positioned at the second side; and an orientation component configured to detect an orientation of the mobile device; and when the detected orientation is indeterminate: in response to a phone call being received or initiated: said processor is arranged to activate said first microphone, said second microphone, said first speaker and said second speaker; said processor is further arranged to play an audio received during said phone call through both speakers (214, 216), and said orientation component is configured to process audio signals received from both said first and second microphones; and in response to said processor determining that the second microphone is receiving an audio signal level greater than the first microphone, said processor is configured to activate the first speaker and second microphone and to deactivate the first microphone and the second speaker; wherein for the processor to determine that the second microphone is receiving an audio signal level greater than the first microphone the processor is configured to subtract a signal substantially equivalent to the audio produced by the speakers (214, 216) and received by the microphones (218, 220) from an audio signal from the user received via the microphones (218, 220). a first speaker positioned at the first side; a second speaker positioned at the second side; a first microphone positioned at the first side; a second microphone positioned at the second side; and an orientation component configured to detect an orientation of the mobile device; and when the detected orientation is indeterminate: in response to a phone call being received or initiated: said processor is arranged to activate said first microphone, said second microphone, said first speaker and said second speaker; said processor is further arranged to play an audio received during said phone call through both speakers (214, 216), and said orientation component is configured to process audio signals received from both said first and second microphones; and in response to said processor determining that the second microphone is receiving an audio signal level greater than the first microphone, said processor is configured to activate the first speaker and second microphone and to deactivate the first microphone and the second speaker; wherein for the processor to determine that the second microphone is receiving an audio signal level greater than the first microphone the processor is configured to subtract a signal substantially equivalent to the audio produced by the speakers (214, 216) and received by the microphones (218, 220) from an audio signal from the user received via the microphones (218, 220). said processor is arranged to activate said first microphone, said second microphone, said first speaker and said second speaker; said processor is further arranged to play an audio received during said phone call through both speakers (214, 216), and said orientation component is configured to process audio signals received from both said first and second microphones; and in response to said processor determining that the second microphone is receiving an audio signal level greater than the first microphone, said processor is configured to activate the first speaker and second microphone and to deactivate the first microphone and the second speaker; wherein for the processor to determine that the second microphone is receiving an audio signal level greater than the first microphone the processor is configured to subtract a signal substantially equivalent to the audio produced by the speakers (214, 216) and received by the microphones (218, 220) from an audio signal from the user received via the microphones (218, 220).
