The Hexa is indeed really well tuned. I do not find it necessary to use EQ with it.

I use more than a dozen headphones and IEMs regularly, another dozen or so occasionally, and the rest are nice to look at (except for the ones in a big box in the back of my closet - those I could probably do without).

Sennheiser Amperior , blue version. Worn backwards - the cable should be on the right side.

amazon music has an interface that was designed by people who hate its customers. It appears to be tested by monkeys. Spotfy has its issues, but at least some thought went into the interface. Still tested by monkeys, though.
