It seems to me that it uses the same drivers as the sporta pro, ksc35 and kph30i; which in turn are identical to the porta pro with the difference that the former are black and the porta pro are blue. The difference in sound between the kph and the porta is due to the small foam sheet behind the driver in the kph. If you remove that foam, they sound exactly the same. They are use the same driver.
So these seem to be just some porta pro drivers in a new headband with the cable thing.
That’s nice, they sound pretty unique and it’s more than just the the foam on them. Regardless, I’ll end up getting the kph40 just out of curiosity when it’s back in stock and I’ll pick up a dongle too JUST because why not?
If only they supported balanced cables with the utility series we’d be set.
Is the 2.5mm connection not trrs? I might be missing something but wouldn’t a 2.5 to 2.5 or 2.5 to 4.4 cable work to give these a balanced connection?
I don’t know what you’re talking about, the headphone does not have 2.5 anything, only 3.5 mm.
It’s a 2.5 to 3.5 cable. I believe the 2.5 end is what connects to the y-split coming from the phones.
probably worth a shot. What Zeos showed in the video was different. I’ll find out when mine gets here. Having koss headphones on the same gear as my Ab1266 is going to be amusing.
I will be interested to know how it works out
You can see that the 2.5mm part is only TRS, so single ended.
Maybe it would be easy to mod, just cutting the end of the y-split and re-wiring it? I don’t know. But then, what is the point of balancing this this? I don’t think it ever benefits of balanced connection, does it?
Anyway, what would be a REALLY good move from Koss would be making it a aula le for EU, not like the kph30i 
No you can clearly see that the connector has TRRS, so it’s either balanced or for microphone connection.
AS USUAL USA ONLY! Remember, there’s like 8 billion people are living outside the USA…
Personally, i don’t mind if its balanced or not, but having a detachable cable would be great for 2 main reason
PS i also agree that the US shipping only is BS
Just wait for the Drop version. I always bought my Koss headphones there and it took about 2 weeks
i doubt there will be one anytime soon, koss probably knows this will sell fairly well so why split the profit with drop when they can wait a few months (maybe more) till they sell a few to drop
I would just get the KSC75 or KPH30i in the meantime if you don’t have them already. Or are you in a rush to get those KPH40?
No rush, and ive got one of each so I’m set 
that’s why I didn’t bitch about in my own post just said that it was unlikely for drop to sell them as well
I recently got a headband for my KSC75 and a new set of yaxi pads which make them look very similar to the KPH40. I wonder if my Yaxi Pads would fit KPH40 too. I’ll definietly get a pair when they’re available
probablly, the KPH 40’s pad are smaller so makes sense that it would fit just fine, and if zeos is right, you don’t even need them
