    I have a jar 600 incoming, but I think I may have a jar 650 in my future based on fr on your graph (that bass extension!). Excited to get the jar 600, though.

    Got the 600 today and gave it a listen for about 30 minutes. Wow, brilliant. The control over the drivers is really great, so clean and precise. I'm more impressed than I thought I would be (new toy and quick impressions caveat of course)

    I never much liked the HD600 to begin with, so never pursued a JAR650 w/@ext1. Interesting to read these brief but positive comments about it...hope to read more impressions about your JAR600.

    I can tell you the JAR650 is also brilliant (IMHO)--building upon the pleasing basic voicing of the stock HD650, w/everything that's good getting even better.

    Thanks to @Hands, I got to try the latest iteration of the JAR HD650. TL;DR, my impressions roughly coincide with @Hands' opinion on them.

    To me, these sound like a HD650+. The sound tightens up a bit and it sounds more controlled. The most noticeable thing was the bass; these do go some way into fixing the looseness in the bass. This also affects the bass-to-mids transition; the headphone sounds more cohesive in this region to my ears. However, it's still a HD650, so they're not going to deliver phat planar bass or anything like that. Secondarily, the mids-to-treble is smoothed out a bit; anyone slightly bothered by a little heat in the lower treble of the stock HD650 may find these a bit smoother.

    I'm unsure whether these are more resolving than the HD650 stock, but the details are a bit more obvious with this headphone. The stopping behavior is where the JAR HD650 sounds more controlled, and possibly why it seems to sound a bit blacker in background, making the aforementioned details stand out a bit more.

    I should mention build quality; these do feel pretty solid. For those worried these might feel like a grade school project, they don't. Also, interestingly, I find myself turning the pot on the Starlett up with these; they don't seem to play as loudly as my ZMF stuff, or the stock HD650.

    Speaking of Starlett, amp synergies carry over from the stock one. I thoroughly enjoyed these out of both Euforia and Starlett.

    I like these, but it's important to bear in mind that these are still a HD650. Any complaints about the stock HD 650 is likely going to carry over to these.

    Yes to both. I haven't touched the earlier version yet.
