If you don’t consider that a sign of a fake product, I don’t think you’re being objective. Fake products put significant effort into looking like real products, many times you need to take them apart to find the differences.
To be fair though it's not as clear as I was expecting, but I'm no expert so not really set up to do any proper testing, the room its in is probably acoustically awful anyway, etc. It's certainly not awful even if it isn't what it says it is, it's several steps up from the dirt cheap 'Tonor' branded and unashemedly 'Chinesium' thing I used before it.
The great thing about Amazon though is that after this thread I contacted support (way out of return period) and they've shipped a replacement. I'll see if it's the same; if it is, of course that doesn't prove anything, but I'll be very interested if it does seem (more - still wouldn't know for sure of course) real to see what the differences are in packaging/construction/printing etc.
Both of these two are identical inside too, same board revision even. (And not every penny pinched like you would if you were faking - gloss black solder mask, as well as on a second PCB whose only job is keeping wires tidy and displaying a silk screened revision number.)
[edit: Further to edit above, it's actually 'C-Media Electronics, Inc. Blue Snowball', and the main chip is this one: https://www.cmedia.com.tw/applications/microphone/CM6327A so presumably both microphones use it and the same assembly house (whether the same design or not) and the EEPROMs' manufacturer/product strings are either getting mixed up or all Blue, whether by mistake or assembler realised they could get paid double to flash once.]
That... yeah, good point. I don't know why that didn't occur to me before. (I was previously thinking they probably just genuninely use some same chips, or even both brands farm it out to the same shop, and both genuine microphones are the exactly same, just differently packaged.)
For computer equipment, I shop NewEgg because their search rules. I wish there was a NewEgg for other stuff. I'm more than happy to pay more and wait a few days extra to have a search that doesn't suck.
What I have found though is that the quality of search results, the experience of using the site, has seriously deteriorated in the last two or three years. It's like AliExpress or eBay now.
I used to read other countries' Amazon users (e.g. .com) complain about this and think what are you talking about it's great, but yeah, now... I still get as good stuff from Amazon because that's what I buy, I just have to wade through a lot of crap to get it.
