Hi Steve Tx for the reply. No the headphones are not equalised for my pinnae in fact not quite sure what you mean by that, iI am talking about using generic hrtfs. It is also possible to localise static objects. Something that close to the ear would probably fall firmly within what is called "the cone of confusion" but that's a location itself albeit blurry. Also important to remember I am asking about suitable headphones for monitoring not necessarily the best binaural experience. So the headphones that would translate best to whatever most people would listen on. In the studio that used to be ns10s but now is probably genelec. However the concept is the same, which headphones are best to produce binaural on yo successfully translate to the widest range of headphones, preferably without losing quality for those with hi end headphones. In the mastering world this is generally something like bowers and Wilkins speakers.
