Currently my 2 beloved closed back HPs are Aeon 2C and AudioTechnica W1000Z. They have many differences signatures but I love them both.
* Aeon 2C are just great for electronic/soundtracks/rock, general very univeral with great amount of micro and macro details, greatly extended bass, clean pure sound with power on slightly warm side.
*ATH W1000Z - eterical like experience with analog coating. One thing describe may describe them - they make yours songs like you would listen to unplugged music performance. They are perfect for Jazz and Female Vocals, but Yello also sounds interesting and catchy with these

They have poorer bass extension than A2C or Nightowls but all in all they are now replacing my Nightowls and I will have to sell them.
