If the device cannot play stereo sound, the headphones will not replicate stereo sound. This is due to the specification of the device and is not a failure. Test this by connecting the headphones to a device equipped with a stereo output (e.g. digital music player) and check if sound can be heard from both channels.

NOTE: This can be checked by turning up the volume of the playback device or by connecting a different pair of headphones to the playback device.
