I've only been listening for 5 days or so, but I haven't stopped listening. I haven't even done any critical test track listening, although that probably won't come for a while since I am having too much fun at the moment. A Note About the Tips: So, the provided silicone single flange tips are garbage for me, no good seal at any size. The andros I got (used, from @PoochZag, at a helluva price thankyouverymuch) did not include spinfits; I have some coming this week, and will have to see how those go. The comply's are ... ok, they give good seal, and the listening is nice and easy, but I hate getting comply's in and out of the ear. It feels like a production, and I am lazy / too often interrupted at home. For the moment, I have some spare double-flanges lying around for my rockets, and tried those out. The fit is awesome for me, and I notice a little more top-end presence, but not that big of a deal, which is nice since I feared it would turn me off. I will do some proper comparing of the spinfits/double-flanges/comply's once the spinfits arrive. Sort of Compared to UERM, also the Bass: The things that impress me the most are the air at the top end and the bass. Both are almost impossibly natural feeling, they easily top my UERM in this aspect. Also, and maybe this is just me getting older, but I am secretly liking the shallower insertion, and find them to be less of a nuisance to don and doff than the UERM. I used to crave that deep penetration (har har) after years of using old barrel-type shures and the venerable er4; I used to think that good seal/bass/everything was only possible once you got past the second bend. No more. Sort of Compared to HD800, also, again, the Bass: The andro reminds me a lot of the HD800, but I do not get the long-session fatigue that made me ultimately sell the 800s. I have said before that I am not the most susceptible to treble issues (except in extreme cases, typically involving closed cans), but I presume the milder treble compared to the HD800 is what lets me listen for longer. Also the bass is WAY better than the HD800. On that note, I find myself liking it more out of low z-out source (currently the GOV2+∞). I think it is not so much that I am a basshead, but that the bass is really freaking good. However, other likely factors include: I listen at lower volume when I am just grinding through a records review at work; and I have recently been giving a lot of time to my TH-X00, which also has tha sexy bass. I was worried, based on reviews, that they would be too like the HD800, and I would find myself pinned between a desire to just listen and an overly clinical presentation. This has not been the case. Ah, but the Hiss: The drawback has, of course, been the hiss. It is awful. I am currently using my UE attenuator until I calculate a more permanent solution. The attenuator kills the air at the top for me, and muddies the bass a bit. Not too bad, but disappointing nonetheless. This makes me worry that any solution will carry these same effects. If anyone has thoughts on this, I am open to suggestions. And, a Note About the General Fit: It's great! I have previously HATED the shure SE535 fit, (don't get me started on the bulbasaur that is the SE846), and was skeptical about the andro. Somehow, they are weightless once they are in, and I have had no issues with the metal edges rubbing or digging in against my concha. it helps they are really light, and for me the cable angle is enough right that I have no issues. I can see this being very person-specific.
