These Ethers were the original Ether C's. Diagonal weave on the fiberglass cups. They were sent back to Mr. Speakers for the upgrade. They came back sounding like a new headphone. There was immediately a deeper, richer Bass and sub Bass that was missing before. A much fuller overall sound throughout the spectrum. The overall balance sounds great to my ears, the treble even more scintillating, than before. I listen to more Jazz and Classical than Rock and EDM style, so my tastes go to a more balanced sound and accurate reproduction. I use minimal EQ with most recordings. At the home set up they are paired w/ the Cavalli Liquid Carbon through a Mojo Audio DAC. But, what I find, is I actually love to listen to these portably. I live in a rural area, where it's relatively quiet, and I love listening to these through the Oppo H2 amp/DAC and played through the iBasso DX50. The DX50 is bit perfect, so with HiRes files, and the Oppo's HiGain, It's amazing all that you can hear out of doors! It's a great pairing and a wonderful treat to be able to be mobile and still hear music like you would late at night, on your home system. That's one of the nice things about the closed cups. Wind, external noise is minimized so you get more music and less outside interference. Very happy with this upgrade. I can highly recommend it to those Ether and Ether C owners who might still be on the upgrade fence.
For those who prefer EDM, rap, et.al these will rock your world w/o sounding distorted, bloated or Bass thin. I believe you'll hear "through" alot of the din and into the lyrics with these cans. Certainly worth a demo. Remember the C's do travel, maybe w/ a hoodie over in populated areas.

Ether C Flow has a mysterious distortion! A 'U' shape / 'V' Shape coloration that is bizarre i notice. It feels like a Punchy and Neutral and Bright headphone. But theres a strange warmness and upper midness happens out of nowhere i notice, that gets shadow by the brightness to cover the V/U shape. It is bright. not as bright as the HD800 but a spike dose happen here and there. This must be due to the mysterious distortion. Almost everything you said is kind of the opposite of what i am writing. It has a distortion problem, it is bloated. BUT because its punchy and clear and neutral and a little bright here and there it overshadows those other areas i mention but its still there. It seems we are still 5 to 10 to 20 years away from making a HD800 or Utopia closed back headphone!!!!
