I'm pretty sure it was never actually stated how many units have shipped out so far. Perhaps you're thinking of the previous update and simply that the first two tiers were indeed the first to ship out. It certainly was never posted here.
Would be kind of surprising if only 250 units shipped in over a week. Before the sticker issue and the halt. Unless they were waiting on monitoring the first shipment to see how quickly they were delivered.
They did confirm 2 batches and after that nothing more. During my research I only found very few people with higher order numbers than 2xx. In fact three people with supposed #1000 numbers didn't check their number correctly.
I thought they would be faster too, but I guess production is still ongoing and slower than expected?
Now regarding the whole hiss thing:
I actually don't get why some people are so riled up about others being discontend with the hiss. I'm someone who hates hiss with a passion since my mind ALWAYS focuses in on it.
Im sensitive to that crap and apparently at least one current owner is too.
It's also a fact that this is a 400$ headphone which shouldn't be held to standards from 15 years ago just because it's full of tech.
I don't have a problem with somebody lile MLE who doesn't mind the hiss and who (to his own accord) probably doesn't hear it as well as others because of constant fan noise that maybe even damaged his ears.
I don't have a problem that people don't mind or don't really notice the hiss.
I DO have a problem when those people suddenly jump on those of us that are not able to tune out noise that is not to mention reportedly louder than that of noise cancelling bluetooth headphones in lesser price ranges.
And it IS reasonable criticism when they advertise a 400 dollar headphone with distortion free drivers that are useless because the amplification creates more distortion than anything caused by drivers ever could.
Those are reasonable criticisms.
Granted, many of us go too overboard with wording and attitude, not having even heard the headphones yet.
