Sennheiser MKE 600 only recording left ear

just purchased a Sennheiser MKE 600 with hopes of improving my audio and it hasn’t made much of a difference… the sound is not that much better than the previous LAV mic and the Sennheiser only records audio on the left ear when using my DSLR camera…
Any pointers on how to ammend this and improve post audio would be appreciated

How have you connected it to the camera?

Could it be the camera is expecting a stereo input and you’re using a mono input?
