Hi guys, so in my dabbling with speaker building, I think its good for me to have a reference. I do have my little Usher S520 bookshelf speakers but I'm thinking maybe a pair of good headphones might work out better. I'm looking for something not too skewed towards bass heavy or too bright. Something right in the middle. Something that I can listen to a song and kind of know what it really should be sounding like so when I go back to my speakers I'm working on, I can more easily spot flaws. This may not be necessary but I figure it cant hurt. I have an old Audiocontrol SA3050 meter which I use for rough measurements but I'd also like to use my ears 
So I dont know much about headphones but I've got some choices I narrowed down to so let me know if any of them are ones I should totally be striking off my list.... or if there is one that the majority of you have listened to and which sound pretty 'correct' or accurate if we can say that.
Sony MDR-7506
AKG 172 HD
AKG 171 MK II
AKG 240 MK II
Sure SRH840
Sennheiser HD518
Audio Technica AD700
Beyerdynamic Custom One Pro
Ultrasone HFI580
Grado SR125i
Any help is welcome. Want to go shopping soon LOL
