Michael, your new microphone has no bass and very little mid range to it (for me).
I presently have three connected headphone I use to listen to Down Range Radio:
AKG K702 Audiophile - home audio
Plantronics Gamecon 777 - game pc
Shure SE530 Sound Isolating head phones - iPod
And all three are exhibiting the same audio. You sound clearer and slightly more open than the old microphone but I can't seam to compensate for the excess treble of your new one, there is to much high frequency for me.
Hope it helps.
