Left ear speaker not playing when using bluetooth

My Beats Solo 3 left ear speaker does not play when using bluetooth. When it is plugged in with the cable to my phone the speaker also does not play but when i plugged it in to my computer the left speaker did work but at only about half the volume of the right speaker. Is there any explanation for this?
