Thanks,I had the same problem last week. Before coming blu, the purple light took longer (even to 20 minutes) and some times switched from blu to purple during listenining. Then I put it sounding with a cheap headphone the whole weekend 4-6 hours working, 1 hour pause. Now is working like before, and when I switch it ON and Off I do it always with the cheap headphone plugged. I Hope it will continue to work as it is doing. "It was dependent on which outlet I had it...
Some people is asking me things such this:
"Ok, I would like to write a report card but I do not own Dt880 or HD600, how can I do?"
Referring to this "rule":
- For reference we think about HD600 and DT880 headphones, they can have an average about 6.5 to 7.5.
It is not mandatory! It's not so strict. It's just to give an example.
I consider 10 to be the best, not necessary perfection.
Till now I've haven't received a lot of report-cards containing a lot of 10 inside.
Also the low judgments are rare. Not a great amount of 4 and 5.
We are trying to collect data to build Headphone report (report card) If you want, please help with your contribute:
Judge the headphones !!!
IMHO after 3 minutes, and may be less, is always based on memory
I think a good use of common sense is needed, I think I know pretty well some of the headphone I do not own anymore. So I will evaluate them. We haven't put any rule about this.
