I had mine for a couple of weeks now, so I thought I would add my bit to this thread. The pair I got from the Jersey company had the aforementioned markings for each ear piece and a cable which was 1.8m long. The cable length you get seems to be down to pot luck at the order picking stage at the warehouse, although the official line still says it should be 1m.
The sound coming out of these cans was chirpy at first but settled over time. I just left them to burn in for a few nights on a fairly varied play list (30+ hours or so), and could not be happier with the improved listening experience. I feed them off of a fiio e5, which appears to be just about enough to tackle the NS1000s once noise cancelling is on. It should last until the next time I upgrade my sound setup.
Speaking of noise cancelling - it works!

I got exactly what I wanted in this department - active attenuation sufficient to block out most background and computer related noise. It is pretty hard to reach me now, which can be a handy feature in a shared house.
The build quality is reasonable on these headphones, although it could be much improved for the money - original retail price - Goldring had in mind. A plastic headband in anything meant for travel is just asking for trouble. I will keep an eye on things here and will see if any cracks develop in future.
Now the quirks:
1) The left ear piece sounded a tad louder from the get go, but not always. After some detective work, I figured out it was the fiio causing this when bass boost feature on it was not enabled.
This particular balance issue with the e5 has been spotted by almost all credible reviewers, so it was easy enough to discover and address.
Fix: turn the bass boost on on the fiio e5 and adjust your sound controls to compensate; alternatively, use a different amp or plug the NS1000s directly into the source.
2) Cacophony bonanza when noise cancelling was on!
Fix: swap the stock battery; mine lasted only twenty odd hours and I did not see the flashing LED at the time. :C But hey, that's what rechargeables were made for! If you don't happen to have a spare battery at hand when chaos strikes, just turn ANR off - a non faulty set should be fine working in passive mode.
3) Their impedance goes up, when ANR is on, beyond the maximum specified for an Asus Xonar DG and my little fiio e5.
A non issue for me really, but technically they will be harder to drive and you may experience some clipping or general minor distortion of sound at medium-high to very high volumes. e5 is also known to play up at its maximum output.
Fix: adjust the volume to sensible levels when ANR is on or get a more powerful headphone amp, or a sound card with one integrated e.g. Xonar STX.
Hopefully, this little rant will give folks a few more troubleshooting avenues, if they come up against similar issues.
Overall, I can't fault Goldring NS1000s in the sound department for their current going price - good value, even with risks and possible returns factored in. I struggled to find an alternative with a similar sound signature, which I liked to begin with, and ANR, for the money. Your mileage and tastes may differ, of course.
I feel for people who got faulty goods and were messed about by the retailer - been there myself; however, such is the nature of the online bargain hunt - it is a gambler's paradise and who dares (or complains the loudest), wins. Don't give up people, stick to your guns and demand what you paid for.
