This misunderstands the purpose of both target curves and headphone measurements in general - and I completely understand why this mistake often gets made, and I see it quite commonly. I'm doing my best to try and counteract the narrative that seems to emerge when people see graphs, targets, and EQs, that "all headphones should be tuned to the Harman target". No, that's not at all the purpose of what I'm doing, even if certain other reviewers treat it that way. What's more important than adherence to a target is that the balance between fundamental and resonant harmonic tones is intact. Harman's ear gain region (the area where our physical ear amplifies certain frequencies) is based on the in-room target derived from flat-measuring speakers, and it happens to achieve that balance (which flat-measuring speakers will also achieve), it's just shown at the eardrum reference point instead. The FR can be over or under the target in various places, as long as that balance is reasonably well-achieved. This is something that the Liric seems to do well for the upper mids and lower treble - the most challenging part to get right.
But beyond that, I'm going to echo the wise words of a friend of mine here by saying that headphones shouldn't be tuned to the Harman target, rather they should be evaluated in relation to it. That is to say, we understand what X sounds like, here's how this sounds relative to X. You don't need to like X, but X is a known reference point - a datapoint that allows us to better understand how the headphone is going to sound in relation to it, and this happens to be the one that uses the best publicly available and most widely adopted research on the subject. The purpose of the target is not to say "this is what everyone should like", but rather what people do like, as opposed to any other reference point.
Now when it comes to EQ, the reason to do it is to adjust to your preference. I personally prefer a kind of sound that's more similar to 'reference', and as we know, most listeners also prefer this. Does that mean you do? Not in the least. Maybe you like more bass, maybe you like more treble... this is where you need to understand your own preferences, and adjust accordingly. In other words, I don't tune my EQs to match Harman and call it a day, and that's also why you see some deviations in my results as well.
