Hello Clyde and welcome to the Cow Audio Forum.
Size does matter, but not in the way discussed here so far.
Larger diaphragms move more than smaller diaphragms. In doing so, they generate more voltage; more signal. As a result, you don’t need as much gain to get a usable signal. Smaller diaphragms suffer from increased self-noise simply because they aren’t big enough to generate the same voltage of larger diaphragmed mics.
Best thing you can do is try another lav and see. Everything folks have said before this are true. Azden is not known for their quality of sound. The best wireless lav system I’ve every heard is the Audio Ltd. 2040. At $5000.00 a set, it better be. Here’s a link to a voice and a music track I recorded with the 2040 back in 2007 while the 2040 was here for review.

As mentioned, wide frequency response is not always your friend. I found that my countryman mics, combined with Audio Technica U100 wireless resulted in some problems. WHen I was in an environment with low frequency ambient noise, that noise would modulate the compander and I could hear that.
I had some lectrosonics here and compared them to the Audio Technica U100. I clipped both lavs on my chest and without looking at meters, adjusted levels to be even in each ear. Each mic was panned to a separate ear. After I got them “balanced” I looked at the meters. The Lectro level was about 4-6 dB below the Audio Technica.
I think Lectro was using an approach similar to that used by AM radio engineers; cut the low and highs and compress or limit the remaining signal a bit. In doing so, you get a track that is more persistent, even though it’s lower.
Then too, mounting any lav has a dramatic effect on how it sounds due to body resonance.
Hope this helps,
