So Rich sent these for a listen and checkup. These are my impressions:
These are a little lean. But then I do tend to like IEMs that others consider bassy. I was honestly expecting quite a bit worse given what I've heard about them. I was expecting an analog phone line. These are not that bad, but they do lack dynamics, and have a somewhat recessed/weird mid-range. I feel there is some glare to these as well. Channel balance seems off in this particular set. Again, to me bass does not satisfy, but others might disagree.
Versus the Tenores, I definitively prefer the Tenores which have more impact and IMO much better mid range.
Anyhow. Here are some measurements.
I did measure the Tenores that Rich send along with these and they measured very close to the Tenores that I measured in the past.
Here is a comparo:
The channel balance might be a defect of this particular set.
Many thanks to Rich for supplying this set!
