Well it's been a long time coming, but it's finally available. AspenMics listed an HQ-SE Locking TRS Lav microphone on their website sometime last summer, but it was never available for purchase. The hold up apparently was wireless interference issues which required better insulation (since it's primary use is on a wireless system).
Grabbing another inexpensive aftermarket lav mic (JK mics), I did a quick interference test holding it close to the power supply of a few electronics. Sure enough the cheaper JK microphone was extremely prone to interference.
The JK microphone had a physically smaller capsule compared to the AspenMics HQ-SE (not sure if there's any sound difference due to the size).

The cheaper JK mic also had a thinner cable at 1.6mm possibly less shielding from interference. The AspenMics HQ-SE cabling was measured around 2.04mm barely a difference, but I guess it's enough to prevent wireless interference issues.

Obviously the best thing you can do for your Evolution Wireless Kits is to purchase the OEM Sennheiser ME-2 LAV microphone. But at normal retail $139 Dollars, that's gets pretty expensive each time you have to replace one or carry a spare for backup.

The AspenMics HQ-SE to my ears can sound just as good especially if you want to spend a little time EQ'ing it in post and currently lists for under $45 dollars (that's like 3 for the price of 1 sennheiser). Even cheaper if you go for the 2 pack or 3 pack bundles!
