Maybe it updated your firmware as well, so you would think you heard better quality.That's why I still have the old one. It's showing no signs of its age, except for dents, missing paint, and things like that. It sounds and acts exactly like it ever did. I used the new transmitter as an experiment at band practice last night. If anything, the updated code or whatever it is, sounds just a little clearer. That's true of both the old transmitter and the new one. Not that it sounded blurry or muddy before. There's also the possibility that I'm imagining things.
