Including the triple flange eartips but excluding the cable connector it's roughly 25mm (1 inch)

How do these deal with noisy/loud environments?

These are perfect for noisy environments, you won't be able to hear any outside noise. I was at an indoor Netball games and could not hear any of the high pitched whistles being blown at all. These IEMS are really good.

Are these geared more towards professionals? Im a casual listener, but I'm looking to upgrade to something more serious than regular cheap earbuds.

Speaking as a professional, yeah they have a pretty neutral and accurate sound with very good isolation, which I greatly appreciate because I can't stand exaggerated consumer-oriented sound signatures. It sounds better than anything else remotely close to this price. However, to achieve this great isolation and accuracy, you have to use those 3-flange tips and insert them properly (very deeply-as deep as they'll go). It takes a bit getting used to and may present a comfort issue for some, but for me, it wasn't a big deal and I got used to it quickly with no discomfort.

Are the foam or silicone flange tips more effective at noise isolation?

I find the triple flange silicone tips better in my ears. But I have narrower than normal ear canals so the foam does not fit very well.
