I'd also choose HE-500 over Elear. Elear was a huge disappointment for me.
I'd also say comfort is an issue for Elear too if talking about long time gaming. It's pretty heavy.
For gaming, you could even consider the cheaper HE-400 and save a lot. Used HE-400 is what $150, vs. a $800 elear? The HE-400 has an exciting sound signature that works well with games due to the elevated bass and treble.
I have both an HE-400 and an HE-500. HE-500 is balanced with a fantastic glorious midrange, HE-400 is better for EDM and exciting sound with a more V shaped tuning. I enjoy them both.
FWIW, the DT 1770 and 1990 are very comfortable and work well for gaming too. I know you liked them before, not sure if you sold the 1990 or still have them.
