One of my minor issues with it, is that although it does record decently through the builtin microphone, it's mono and of limited dynamic abilities. I found that I could get decent recordings by using the stereo mic I bought many moons ago for use with my DV camcorder. The Sony has a mic jack on it, which is perfect, but it only has two gain settings "High" and "Low". It's enough to get by, until I buy a real portable recorder.
The one problem I had with this setup though is that there was no way to easily carry it. I decided to make some sort of mounting adapter to attach the microphone to the voice recorder. The mic came with a clip with a hotshoe/tripod mount on it, as well as a little extension arm which also has the same abilities. I decided that the best way to take advantage of this was to mount a screw through the case of the voice recorder, and attach the mic to this.
I started by mapping out the best locations for screws. I decided to make two holes, so that I would be able to switch it around if I needed to. The screws I have, have heads that are a little too rounded, so they force the battery cover up a little bit, but it's good enough for now.
In the future, I'd like to try flatter-headed screws for this design. I'd also like to perhaps try a 3D-printed thing, which the voice recorder can be snapped into, and the microphone slid into the bottom, to make it more sleek.
