Yes, I ordered a pair.....


So, on May 24th, I received my HIFIMAN HE-R9 through Amazon. I had watched and read every video / review on these, and when they went on sale for a ridiculously low price (another poster here alerted me of this), I figured I had nothing to lose. If I did not like them, I would return them. I have always been a headphone guy, but only about 10% of my listening time were through headphones. I have owned many headphones over the years, including electrostatic phones by Koss and Stax. I owned for a short time, AKG K1000 (on permanent loan from a buddy of mine who was the rep in my area), which were a very interesting sound, but did not excite me (I might be the only one). Just like speakers, amps, dacs, etc., headphones are a personal choice. Choices from open back, closed back, dynamic, planar, on ear, over ear, in ear and so on. Shielding against outside noise, or not, for home / studio use, or portability for travel / on the go. What diversity. And the pricing? All over the place. Not to mention, the pairing of a source / amp to integrate with them, and the listener...in this case, me. Anyway, listening to the HE-R9 for the 1st time, using a highly modified cd player through my Headroom THE MAX, I was very disappointed. With a professional price accommodation, I received my MAX around the same time my comrade Wes Phillips (RIP) completed his Stereophile review, as I trusted his ears, although we were both very different types of listeners. HE-R9 : Bass was in excess....muddy, no detail, and seemed to display this characteristic throughout the midrange. Vocals were hollow sounding and subdued, and the treble.....harsh. Not a performance I wanted. Living alone and owning ss gear makes it possible to have my main system, 24/7, playing recorded music. My Creek OBH-11 is routed through a record out of my preamp, always on. The HIFIMAN were put into "break-in" mode through the Creek, again, 24/7.......until last night. What I can say after a month of waiting, these are a very FUN and enjoyable headphone... using THE MAX....I have listened to several cds I am very familiar with and enjoy "immensely", since my new re-introduction to the R9. As discussed by many, including Paul M., headphones do not give you that visceral feeling in your midsection as when listening through loudspeakers. I love my system for that, a lot. As I was listening to "A Tribute To Jack Johnson", my personal favorite Miles and of which there are many, through the HE-R9, I was hearing details that were not there before, that I did not hear before. There is a spatiality to the HE-R9, that I feel is remarkable. Keep in mind, (1) I listen loud (2) Headphones eliminate the room and its interactions, and I greatly appreciate that (3) I listen for the musicianship, the composition, and of course, hear "everything" involved, for the final take (mic placement, eq, etc). I am enjoying this headphone system, but with anything, I will need more time with them, before I open them up and do a few mods (or just buy a 2nd pair). BTW I am being paid as a seller affiliate for every pair sold through my link (and I have a bridge to sell’ya!). lol     My best, MrD.

@mrdecibel Thank you for clarifying the timeline.  I agree about a week or so (approx 150 hours) for my amps to settle in but I find it fascinating that we could be looking at 750 hours for the R9.  Excellent insight for those of us considering acquiring these in the future.

750 hours for burn in?  Geez. I might be dead before that. I’m serious. I’m approaching 70 at warp speed and not in the greatest of health. 
I want to buy a HP setup but I’ll need things that are at their best a lot quicker!
