GRAS (RA0402): vs Harman IE (this is just because this IEM is particularly Harmanlike. For more information on why we don’t just use Harman IE and 711 at present, here’s some context)
Overall it’s a solid release, since this is basically a cheaper Moondrop Variations, which has been a popular IEM for quite some time now. With that said, I sincerely hope this is the last we see of this trend for IEMs. TruthEar’s very own Hexa is a more balanced sounding IEM, and doing that comparison right away reveals the issue with the lower mid dip that’s likely the result of the old 711 paradigm with in-ear headphones.
No issues with comfort
Subjective qualities are basically the same as on the Variations (unsurprisingly), which is to say… it’s really quite good for that.
One minor difference is that I do still feel the Variations has slightly more satisfying bass, but also there’s some measured difference among these units for the bass as well.
Recommended for those who like a particularly distinct sub-bass shelf, with a leaner midrange presentation. Not recommended for those sensitive to upper mids and treble.
I would have measured with a bunch of tips. Re the graph difference, I expect that’s because we went from 5128 DFHRTF to JM-1 (for 5128) DFHRTF for the calibration, which is a better indication of population average pinna effects. I’m hoping in future the tool we use for our database can better indicate that but currently it doesn’t get reflect that for in ears.
Not sure why all the forums said it measures better with foam tips (on 711). Maybe some weird interactions with 711 rigs that is not there with 5128. Maybe a resonance
The reason for using foams (at least in my case and that of many others) is that it is easier to get a good seal (silicone tips can have a habit of folding and not sealing correctly) and it is also easier to get a consistent insertion depth across multiple sets.
