Dan Clark Audio AEON 2 Noire

I have this can for a while now, burn in is complete and this is a good one. I switched about 10 years from Dynamic headphones to Planar ones and had previously a.o. a Dan Clark - then called Mr. Speakers- Alpha Prime. A good solid headphone with fantastic, yet darker, sound. I recently purchased this one, much more modern look, and what a sound. Crystal clear highs and mids, tight (but not overwhelming) bass. And no fatigue at all, I can listen for hours without congestion. Real "Aural Heaven"!

Had this little bastard for exactly a year now. Mostly used it for production and mixing (on the pro side). Once your brain gets adjusted to its slightly sub-elevated sound it has proven to be an extremely analytical pair of cans. In case you want to use it for the same purpose, please note that there is a smear on the mid low, essentially turning the mud into a smoother brown puddle. For this and the coloring I would say is more of an audiophile piece.

The carry case and fact that it collapses is by far the most useless feature on this pair. This is NOT a portable product. I mean it would be, but you need to haul around a PA system to drive these (a competent amp is definitely required). It does, however, sound great on almost anything that can feed it with "kilowattses". The sound quality, oh boy, is more than worth it.

The headband and way is fixed to the wires is a very bad design choice. It came loose on me and fell off multiple times. The wires, if you touch them, are a very long sustain musical instrument playing only G#. The paint is already rubbed off on some corners and the foam tends to turn out of place inside the cushions. But they are extremely comfortable.

Can you find open back earphones better and cheaper than this one? Sure. ... Like almost all of them at this price.

Can you find closed backs better than this? No, probably not.

These headphones a tuned very nicely (I prefer them with the black felt inlays). Very comfortable. Planar magnetic usually tend to be on the heavier side (magnets) but these are very light due to the materials used.
I use them in the office and can wear them for hours. Noise isolation is pretty good.
They are closed back but feel a bit like a open back by the sound. It is very wide. They also respond well to EQ, so give them that bass shelf and feel the rumble.
The only small negative I'd say is that the earpads deform very quickly (There are threads about it), you can bring them back to form by pulling a bit on the skin, but still..
