I received a new pair of Aeon 2 Open (A2O) late last week and burn-in is in progress. Avoiding detailed impressions, but here is my 20-hour take with a Schiit Hel and my ears - A very happy paring. Listening to La Nozze di Figaro (
Amazon Music link ) almost had me jumping out of my skin a couple of times. (Especially the whistle in No. 10) The stage is in my head but well defined. (Caveat - I am using 6' VIVO cables. Also, my ears have had a hard 66-years of live concerts, motorcycles, military weapons fire, and B-52 start-ups.)
Pretty early to claim which cans from my wall would I rather put on my head when I plant myself in the listening chair. I have something that offers better detail, another with objectively better FR, and the weight of the A2O has noticeably more heft than my E2s; but over my ears, with my gear, I quite like the A2O so far. No regrets.
I wouldn't hesitate to recommend a Hel and A2O pairing for an 'under $1k' setup. I'll move the cans over to the Jotunheim and Cavalli Liquid Platinum (re-capped) after the burn.
Like a few other cans I have, "better" doesn't mean 'better liked.' Nice job,
