It’s probably fine, but I recommend getting a headphone hanger meant for under the desk. I have one stuck onto the bottom of my Focusrite, and I just hang cables off of that (along with my headphones). I use this one: https://www.amazon.co.uk/dp/B01LL3WG1K
Im actually glad someone made a post like this. Im considering getting something to hold my headphones too and was wondering if this hanger would become an issue in the long run?
