Great, thank you for the answer.Hello,
The slim transport case (in the middle of the table between the two big boxes) will look similar like the standard packing. The difference is mainly the height and that the headphone parts (drivers and bow) are placed dismantled into to allow the slim form factor.
A picture taken at Berlin Can-Jam is attached. Better pictures with details will follow on the www.Mysphere.at homepage soon.
The variant 3.2. is using an impedance of 110 ohms instead 15 ohms as 3.1. All relevant other spec. details remain the same.
And the sound of the 110 ohms version is going to be the exactly the same? As far as I know the impedance is largely determined by the driver's voice coil and usually the higher impedance means that the voice coil is thinner and there are more windings (layers of wire) and so the better the sound, at least for the same Beyerdynamic headphones (like DT880).
