In my experience K6/ME66 are very nice on Phantom Power; with battery
power I have some problems:
on battery power the noise increases noticeably (by hearing too)
starting at 8 kHz and 2 strong peaks appear in the ultrasonic range.
See spectra on http://www.unipv.it/cibra/res_techtest_uk.html (at the end).
Sennheiser repaired them with little results.
A 15 years old K6/ME66 does not increase noise when operating on
internal battery, but shows a narrower and lower peak around 35 kHz.
