Recommend me some...

[6sAllTheWay]

...headphone music that is dream like, layered, mellow and atmospheric. Music that you can loose yourself in. I am imagining something purely instrumental but if it contains vocals on a few tracks, that is fine. Spacey electronic or slow psychedelic rock? That does not really matter as long as it is good. Maybe someone has some suggestions? 

[lateralus88]

Try this.

[AMindBesideItself]

Klaus Schulze and/or Tangerine Dream

[rogerdil]

Kemialliset Ystävät - Harmaa laguuni - described as psychedelic folk, although not sure about folk part.  Dream-like and dissonant.

[SystematicThought]

Any God Is An Astronaut song

[glaurung]

Alcest - Sur L'Océan Couleur De Fer

Alcest's sound is very dream like. There are occasional screams which you would think detract from that kind of sound but really don't.

[DebraKadabra]

Tangerine Dream

Just coming in here to post that.

[Onno]

Anathema's Falling Deeper.

[Lowdz]

Marty Friedman- Scenes or Introduction do it for me when I'm in a mellow mood. Great headphone music. It's not shreddy.

Or Deuter's Nada Himalaya- Tibetan singing bowl music. Great for meditation and leaving the real world behind.

This site is an excellent resource when selecting earphones: https://www.earphonesolutions.com/beeaforip.html

I have these and love 'em: https://www.earphonesolutions.com/um2dudrineaw.html (granted I have them in black, not clear.)

lol, nevermind.  Headphone Music....

[Heretic]

First question: How much do you know of post-rock? If very little:

This Will Destroy You
Sigur Ros
Hammock
Yndi Halda
sleepmakeswaves
Gregor Samsa

These bands have all made music that is deep, beautiful, and powerful. Lots of layers and dreamscapes at times.

[Big Hath]

Pete Namlook/Richie Hawtin - From Within

https://www.youtube.com/watch?v=7Mu7fKgcVx4

or

Dark Side of the Moog

[Ben_Jamin]

Hybrid - Morning Sci-Fi

[Scorpion]

Sigur Ros.

EDIT: Damn, Heretic beat me to it. Still, try them.

[Phoenix87x]

Try this.

Yes, definitely try that.

[FretMuppet]

If you're feeling depressed, listen to Low - I Could Live In Hope, I recommend the song "Lullaby," so tragic 

For something more jazzy, listen to Laughing Stock by Talk Talk

We're Here Because We're Here by Anathema for something full-on beautiful and climactic

Ghost by Devin Townsend (as was mentioned)

And my personal favourite... 55:12 by Gregor Samsa!!!!

[Zantera]

I second Laughing Stock by Talk Talk.
I would also like to name Godspeed You! Black Emperor, their music is really awesome in headphones. Instrumental, majestic.

[senecadawg2]

Sigur Ros ( ) is great headphone music, I think...

[6sAllTheWay]

Thanks everyone! Some I've heard before (Hammock, Low) but lots of stuff to dig into
