While I think the 009's are amazing sounding headphones, the one problem I have with them is with some of the songs I listen to, at certain parts of the songs I have to turn the volume down because it becomes uncomfortable. I could listen with the volume low with such songs all way through, but then I wouldn't feel as involved with other parts of those songs. I do have my BHSE's volume knob at arms length when listening to music but I'd sooner not have to alter it when needed. I did hear IanG's 007's with no such problem so it's not the BHSE.
Totally agree, it's not the BHSE. That would be the last piece to replace. I'm just saying at normal listening levels, the 009's don't sound bright to me. When I try to push them, and depending on the source material, they start to become too transparent.
