Today I got an UPS box with the following:
It went from St. Petersburg to the Netherlands in roughly 3 days. Inside I found
Ah yes the traveling case with the price inside:
A true beauty as far as I am concerned:
My cables have no left/right marking
But other 3.5mm cables can be used like those I use with my Beyerdynamic T5p.2 and T1.2
Out of the box I was scared crap! These sound like an utter piece of crap! Like an 8khz high-pass filter has been applied
No bass. No mids. Very soft and distant. Reminded me a bit of an incorrectly wired out-of-phase sound; but then with that 8khz high-pass filter.
Mailed Kennerton and they responded promptly, but the answer was of no use: "Do you have a proper seal? We cannot think of anything else at the moment.".
Since the headphones were send by airmail I thought of one more thing it could have been: sudden air pressure changes that deformed the membrane.
Kennerton responded that it indeed might have happened during the air transport of the headphones.
The headphones already sounded like crap and with a small test before sending them back I tested my hypothesis if I was able to 'fix' them by reverting the pressure build-up. What I did was that I put my hand on the ear cup and pressed down while letting the air escape easily. Once the ear pad was flat I "pulled" my hand up, creating under pressure in the cup: instantly the sound returned. All of it. Did the same for the other cup with the exact same result.
I'm letting them burn in for a bit now since they still sound a bit 'weird' to me but that might be the horn sound(?)
