Jammin’ to this on a set of Pioneer SE-MS7BT that was on clearance at JB
These headphones sound great, but personally I find them to have a poor fit. When worn "naturally", they leave a sizeable gap behind the ear because the ear cups don't swivel, and the ear pads aren't thick enough nor soft enough to form an adequate seal around the ear. Pioneer thought of this and tried to make up for it with the contoured ridge on the ear cup, but unless I wear the headphones such that the front of the pads cover most of my zygomatic arch, they leak sound in and out.
Thanks for the gut shots, always love to see the insides of audio gear. I've mostly sworn off any headphone with that oblong shape all the manufacturers seem to love, they never fit me well.
