Hi freediver, thanks for the input and what you suggest are the very ones I was thinking of from HiFiMan. Even though I have had much in very, very good audio gear ..I have not had any headphones since from Audio Technica Eletret Condenser and Stax models around 30+ years ago.
I am fairly focused on what I listen to, mainly classic acoustic Jazz and female vocals that lean towards the Jazz and Standards family of music. I do not have a concern for open back designs where I will do most of my listening. My main system is in a room where I am free to listen, but in my bedroom I am mainly interested in more casual.....heading off to sleep listening. In my main system I have had tube and solid state components and my speakers for many years have been from Magnepan, Martin Logan and back when I started it was the original large Advent and Dahlquist DQ-10. My favorite piece of amplification/pre-amplification ever is the original Conrad Johnson ART pre. ..just to give you an idea of what my choices have been. Take care and Happy Holidays to you and your loved ones.
