Thank you guys for all your comments, for me I purchased today the gr07 BE and for my gf's i will probably get the Flux just hope they will get back in stock to amazon soon..
wanted to ask about the burn in process of the gr07, I have read quite a lot on this subject, just wanted to make sure I got it right about how is it done..
1) The gr07 BE burn in time is 250-300 hours ( 7 hours at night X 40 days ? )
2) I should use a sound like pink noise in loop like in this site: http://simplynoise.com/, whats the difference between pink white brown ?
3) The volume should be just a bit above my average volume sound.
4) The head phones should also rest, and so the best way to do it is just burn them all night each night and in the day just use them regularly.
any comments about 1-4 ? have I understood it correctly ? did I miss anything ?
