I recently picked up the Para II headphones, and—no surprise—they sound amazing after a bit of EQ.
After using them for a while, I noticed an interesting phenomenon: when I place the palm of my hand near the outside of the earcup, the sound changes. With my hand positioned roughly 0–15 cm from the grille, it seems to reflect sound waves and create a noticeable resonance. I was genuinely surprised, as none of my open-back Sennheiser headphones behave this way.
Even more intriguing, at around a 10 cm distance it creates a sense of a wider soundstage, or some kind of lateral layering around the sides of my head. For me, this reinforces the idea that perceived soundstage is closely related to resonances in the mid-frequency range.
Has anyone else noticed something similar with open-back designs?
