Koss Porta Pro.
Yes, makes you think Porta Potty.
These are the simple ones without remote or mic.
They have one cable to each speaker and they have an angle adjustment at the headband joint…
Wonder if I can dismount the headband and attach the speakers to the halo…?
Maybe I can bend the headband to form a clamp that allows it to slide along the halo?
Maybe cover it in heatshrink tube to avoid scratches on the halo plastic…
