Unable to hear back of the head sound effects

I suggest trying a surround sound system.  Once you do you’ll love how immersive a good mix is.  My old man ears have never been happier.  2 channel is still great but Dark Side of the Moon in atmos is amazing.  

In 1978, I built the KEF R104 speakers. (MOODY BLUES) There was a track on "searching for the lost chord."It was titled "House of four doors." There was a break that sent the sound in the perfect circle of not just stereo, but a full circle in front of you. It amazed my mates no end. Now, It takes a circle from front to rear, like it is surrounding me. On H-phones, it does not work at all. It just goes back and fore.

Please try it, it will not take more than a few minutes.

All the best IAN.

CORRECTION, Just played it and

I drink too much, The track I was referring to was "Thinking is the best way to travel"

The phrase only lasts for 40 seconds.

I believe it has to do with loudspeaker setup, the room, and of course the recording. I can clearly hear percussion to the right rear in Euge Groove's song "Twelfth Night". Of course there are others but this song stands out for me.

For those who have never heard the surround effect on a stereo system, try listening to Roger Waters "Amused to Death". There are a few others but this comes to mind.
