Update from my side:
Didn’t get my initial ordered Sundara/Hybdrid Headband, but got refunded.
Through contacting Hifiman I could order it from them (shipped within EU) and received it today.
I also filed the mounting holes of the headband bigger to fit the pins of the original headband like other users did.
I really like the suspended headband and the headphones sit more securely overall due to the higher clamping force.
Even with the higher priced Hybrid headband I can recommend that mod aswell.
