I have an in-ear mic, which does wonders for reducing surrounding noises and also for letting me use a phone normally, but my main issue is with the software itself; I've had issues with it since implantation and they've always been pooh-poohed by audiologists at Hopkins, Tokyo University, and Toranomon. The biggest problem is that it seems to operate on some kind of averaging system -- when there's a noise that's louder than the recent average, everything just cuts out for a few seconds. This is especially noticeable in the morning, where I've just woken up and am trying to get to work, but there are cars and trains etc. making noise and making my hearing cut in and out constantly, which not only drives me up the wall but gives me a terrible headache.
