I did try the Zenith set. It was ‘fine’ bordering on good. I have an extreme anti KZ bias and probably can’t overcome it. I wasted way way too much money in the early days when they were making the first cheap multi-ba sets. I also do not like how they have like 80 models for sale… clearly they are not doing a lot of R and D and I can’t deal.
As far as the bypass vent, it actually doesn’t affect treble, only lows. I can either use it as just a vent or a tuning thing.
I did manage to finally match the DM itself and then added a bit more subs due to my tuning features.
DM in Purple, im in Brown.
Thing is i’ve done this before. I have never found an IEM that actually measures differently at different volumes. I was just messing around graphing stuff and accidentially set my volume super low… realized the graph wasn’t the same.
