The peak at 5000 is the serious killer, it ruins vocals and pushes then into uncanny valley. Luckily they EQ very very well.

Try this EQ https://i.imgur.com/ELAEvJU.jpg and don't even bother with the bass mod, it's a bad mod. Once I found this EQ I have not been able to listen to them stock. Fixes the weird voicing issue and gets the bass to be present and fun.

My T1 can't handle EQ for shit whereas this one never clips or sounds stressed.
