Very cool. I have always been curious about binaural recordings. In fact, I started
this thread a while ago, hypothesizing that it would be a great way to hear other peoples listening spaces. It turns out the gear to make such a recording is not cheap, so it's not too feasible for most folks.
This is pretty interesting way to review and hear speakers though, and is probably the next best thing to actually being in the room. As shopping is done more and more online, and brick and mortar audio stores are becoming extinct, this could be an interesting thing. Kind of VR speaker shopping. As mentioned above, headphones are necessary to experience the full effect.
Put on your headphones and check out this short clip to get an idea what binaural recording can do.
