So if I understand correctly it's as though your drivers were put into a polyester bag covering them from dust. No idea what's TPU.
Then for relatively short listening sessions on a dry and fresh climate it'd be OK closing the ports. Will that be easy or needs some complex dismounting to be done?
I wish you provide some sort of dust protection for the membranes and the stator, that scared me a bit.
So on places of lower humidity than Mumbai it'd be OK to close the ports? I'm all in on great bass response. Not the quantity but the quality and depth.
I have a silver gray dial Longines that looks better on a dark gray strap than on a black one. Dark blue also combines pretty well, so take your poison. The tone in the pic looks like it'd be a good match to the OP dial. Good luck
I don't have the slightest chance to need one of those in the future, but I'd love having one. I've always liked all those buttons, knobs, switches and the tiny screen with grid and scales. Something's wrong in my brains since a kid.
