Can someine point me to an upgraded silver cable that is compatible with these?

I believe these would work as they're dual pin and silver plated copper 8-core feed however, to be honest, the wire that comes with it is great this pair is amazing for the price. Better than my Mackie and Shure 215s by a long stretch. https://www.amazon.com/KINBOOFI-Earphone-Upgrade-Braided-Replacement/dp/B07GQV52BG/ref=sr_1_5?keywords=in+ear+wires&qid=1555336039&s=gateway&sr=8-5

Are these wireless? i have an iphone 7plus. will these work on it?

They can be if you also purchase a .75mm 2-pin bluetooth adapter(s). I purchase the TRN true wireless bluetooth adapters. They plug in to each IEM independently and sound very good with a device that is bluetooth 5.0 compatible.

Where could I get cable conector?

you can by it with 2pin cable in Amazon，search for Replacement Cable

Considering that this item is supposed to arrive today, and it's still showing that it hasn't shipped, can I assume that you are next door to me?

Wait. what? OK, so I will address part of you inquiry then answer your question. If you are promised a specific delivery date along with who the courier is, check that couriers website for tracking infomaion. Without knowing who promised you these details and where are you seeing that this hasn't yet shipped. That would be my initial schpeel on this. Now with your assumption of where I live in vacinity to you, assume that you had heard the elementary school phrase to - never assume... it just makes an ass of you and me. OK, good luck.
