Okay so I’ve spent a long time measuring these and trying to figure out the differences between the Clear MG, OG and Elex (Elear with Clear pads), and I feel more confident using in-ear mics to show this, mainly because they’re more readable and consistent in the treble - where the real differences show up among them.
Sample 1
In-ear mics: Clear vs Clear MG
GRAS 43AG: Clear vs Clear MG
Sample 2
All three compared with in-ear mics
GRAS 43AG: Elear with Clear pads vs Clear MG
While this shows some difference in the bass between the MG and OG, it could just be that the OG I’m using to measure here is a bit of an outlier in the bass (looking at Jude’s measurements at least). But regardless, the main differences here are in the treble as I mentioned.
The MG is noticeably pulled back in the mid-treble, making it somewhat smoother there. While this is a good thing, it also loses a bit of the balance that was created by the Clear and Elex’s three bumps, 6khz, 8khz and 10khz. Importantly, the MG elevates significantly in the upper treble above 10khz, imparting a kind of ‘shimmering’ character to it. While that slight shimmer worked on the OG Clear, due to the three bump balance, the contrast between mid treble and upper treble on the MG is a bit too intense for my liking. I think some may be fine with this though, and how much you notice it will likely depend on factors like age and sensitivity to upper treble.
So, in short, for tonal balance, I think the OG Clear is simply better, with a more even balance in the mid-treble, in spite of the fact that the MG is a bit more smooth there. The OG’s mid treble presence just gives it a bit better focus for cymbal hits, rather than the emphasis towards the upper edge of those tones.
For technical performance, they’re all very similar, but I’d rank them like this:
Clear MG > Clear OG > Elear/Elex
The difference in microdetail and microdynamics is significantly more noticeable between the Elear/Elex and that MG than it is between the MG and the Clear OG. So, I mentioned earlier that the difference in terms of detail isn’t as noticeable as the difference in treble tuning, and I think that’s still true. But the reason I think there’s actually a tangible difference here beyond simply the tuning changes (people often perceive more upper treble as ‘more detail’), is because the differences I hear for detail are primarily in the midrange.
In any case, they’re all great sounding headphones, but my personal preference is for the Clear OG’s treble tuning, even though it can occasionally be a bit ‘gritty’ at times (it’s a tradeoff I’ll take), and I do hear a slight detail advantage on the MG.
For anyone wondering about the MG vs MG Pro, the official word is that they’re supposed to be the same just with different accessories, but I can’t verify that at the moment.
