My audiologist reckons that you have an aid in each ear. Mind you, both of mine are shot, although the left is the worst.

With the ones I have, there is a choice of three switchable settings (that is three options can be set up from a wider choice) so I went for a meetings setting that cuts out out the rearwards facing mic, a music setting and one for picking up hearing loops.

I tried "in the ear" specifically the "songbird" but found that they occluded my hearing and everything sounded as if my head was in a bucket. So, I finished up with "behind the ear" but with open ear moulds so that I can pick up natural sound as well.
