It's an MX300 that someone was recently talking about on the forums, his cat broke the cable and the owner was willing to sell it at an insanely good price rather than get it repaired himself. I... THINK it was a 2013? Maybe end of 2012, the guy said it was pretty new but we don't know the serial number.
I wish I could find a serial number or some other identifying mark on this thing, because I can't.
What I can say is that I definitely didn't get that hard case with padded foam interior like in this review. Would've been nice to have, but the carrying bag alone should suffice.
In other news:
-They weren't kidding when they said the MMX300 feels like a solid, durable piece of kit. If this is an example of typical Beyerdynamic construction, it definitely feels trustworthy.
-The cable quality, on the other hand...let's just say it's that cheap, thin-gauge wire I expect to see on budget headsets. I notice that part, of course, because of the spliced replacement connector I got with it that needed some work...and speaking of which, THAT tripped me up for a moment because the outer ring that you'd solder the tip/left channel connection to...wasn't actually connected to the jack's tip conductor, isolated from any actual conductive bits! Fortunately, I found a part that was conductive, made a solder bridge, and that sorted it out.
This is why you keep a multimeter handy if you're gonna do any soldering work. Check those connections!
In any case, now I've got a secure, solid connection so the channels aren't cutting out and making static noises of any sort. Mission accomplished!
-I just noticed some thin black plastic bits in the headband breaking off and coming loose when I extended the earcups from the main headband. I'm guessing they help hold the tension so the earcups don't slide too easily. Still, that's another point off from Beyerdynamic's construction score...
-This thing's a lot more comfortable than I was expecting. The velour pads are nice and cushy, the cups are deep enough that nothing's really pressing against my ears and the parts that touch rest on soft foam, and big enough to be truly circumaural, and it doesn't feel like I've got a vice on my head.
-Sound isolation is moderate, for a closed set. You wouldn't wear these as earmuffs...then again, earmuffs of the sort I've been given while test-taking are insanely uncomfortable, something I'd never want in a headphone, especially a gaming headset that's going to be worn for extended periods.
-I'm not finding anything immediately offensive about the sound presentation. Vocals don't sound extremely recessed, there's some sparkle, and the bass has punch. I still don't know if this is a "bass-light" or "bass-heavy" set, given that nobody says that with a clear reference point, but these are certainly bassier than the AD700.
-The soundstage is surprisingly large for a closed set, at least enough for headphone virtual surround to do its thing. CMSS-3D Headphone frontal cues sound a bit weird and not as prominent compared to my usual open sets, though maybe I just need some time to get used to it. Mental burn-in, if you will. Rear cues are fine, and pretty exact to boot.
EDIT: I found some distinguishing features, comparing to this eBay auction listing.
-The box looks noticeably different. Less colorful, and the MMX300 is pictured at a different angle.
-The connectors are different! They don't look so cheap this time, whereas my MMX300's mic jack (still the original, unlike the headphone jack) looks like the same kind you'd find on a cheap Logitech headset.
-The earcups have black rims on that one. My set has silver rims.
