do they offer anything for compensation ?
Phew! I'm excited for you bro. Look forward to some impressions compared to your HD800.
I looked for UK stock but there isn't any, Germany is the source and it's sold by www.thomann.de - Shipping took a few days and there was no import tax for me to the UK either.
If I use the upper headband the cable jack tension section bends and touches the base, plus the elasticated headband doesn't go full back when stored this way too as it hits the bracket bits. As it is it doesn't put much stress on the band elastic at all. At best the band extends around 1cm which is way less than what I have extended when the headphone is on my head :p At least this way over time the band will slack and be less tight!
